JBL 705i/708i (7 Series Master Reference Monitors): Jan 2015

For the eight-inch two-way 708i and five-inch two-way 705i installed monitors, JBL developed a new miniature high-frequency transducer, the 2409H, featuring the manufacturer’s low-mass, annular diaphragm design, which was built to allow very high output with low distortion and high frequency response to 35kHz. JBL also engineered two new high-excursion five-inch and eight-inch woofers, the 725G and 728G, enabling the speakers to deliver robust low-frequency output into the 30Hz range...

To reduce enclosure size and installation cost, the speakers are centrally powered by Crown DCi 8|300N eight- and four-channel power amplifiers. The 705i and 708i can be driven by a single amp channel or bi-amplified. For greater accuracy and room-to-room consistency, BSS Soundweb London's signal processor provides speaker tuning, room EQ, and bass management. The processor accepts 16 or more analogue and AES/EBU inputs, and networks with the power amps via CAT5. The entire system can be externally controlled with HiQnet Audio Architect software, a hardware controller, or wireless tablet.

I was excited for a quick moment until I found out that the 7 series would be passive and not active monitors.. Come on JBL, create a LSR 708p (p for powered)

Gooddoc 10-18-2014 01:45 PM

Aha. I think I will have to wait for these. It appears they are the first models designed to be a timbre match for the M2's. I was wondering when they would get these out the door - and here they are. I wonder what the waveguide dispersion is?

I just ordered some SCS8's, but I think I might return them.

Note that the 725G/728G refer to the low frequency drivers in the 705i and 708i respectively. They are not subs are mentioned in the thread title.

Gooddoc 10-18-2014 05:19 PM

I'm curious what the list price will be compared to the 305 and 308.

For those interested, @imagic posted an article on said amplifiers here: https://www.avsforum.com/forum/286-la...mplifiers.html

Looks like these can now be purchased:

www.performanceaudio.com/shop/JBL/LSR-7-Series-826/

It's interesting that they can be purchased individually rather than as a system.

Perhaps the most interesting new info, hearsay at this stage, is that they measure even better than the M2's :eek::eek::eek::eek: Not sure how that is possible :D Probably the differences are minor but it looks like these could indeed be a very nice option if you don't need the SPL produced by the M2's.

Very interesting. I thought these would only be available as part of a package with the crown amps. Looks like you can buy them individually?

A little titbit, Scott Wilkinson recently got to hear an Atmos setup consisting of 7 series speakers (see the 4th photo and accompanying info):

https://www.avsforum.com/forum/286-la...mmy-party.html


3 series monitors were also being used in another demo.

In Studio D, the Dolby Atmos system used JBL's new 2-way 7-series speakers in a 7.1.4 configuration, with pairs of left and right side surrounds playing the same signal.
That statement sounds like 5.1.4 with array of surrounds instead of 7.1.4 :confused:

Yeah, it's not completely clear. For me its just nice to see that these are already out and that presumably Dolby had the good taste to choose these monitors for their demo :)

Hifisound 02-10-2015 11:34 AM

I assume these have "normal" passive crossovers and can be used with usual AV Receivers...

Yes.

"The 705i and 708i can be driven by a single amp channel or bi-amplified. For greater accuracy and room-to-room consistency, HARMAN’s BSS Soundweb London signal processor provides speaker tuning, room EQ, and bass management."

The above however suggests that to get the most out of them, the Harmon processor would be required to tweak their anechoic response (like with the M2s). I don't know if that is the case or not. It depends on what exactly they mean by "speaker tuning." So far the info provided by JBL has been pretty limited.

No official measurements are available as yet but the rumor is that they measure extremely well:

Not really sure what you are getting at. Even if no third party measurements end up being published for these new monitors, there should be plenty of people giving their thoughts on them once they become available. If they sound anywhere as good as they apparently measure, then I would imagine they will be quite popular.

Hifisound 02-14-2015 08:27 PM

Just an observation . No offense intended :)

Zzzzz... 02-14-2015 10:39 PM

^^^ None taken :) Prior to the 7 series, the LSR6328Ps were one of the few speakers I'd seriously been interested in. Part of the lack of third party measurements could be down to the fact
1. they first came out quite a while ago - perhaps back then measuring gear was not as readily available / cheap as it is today
2. perhaps its not that unusual for a speaker not to have third party measurements made - to do a really worthwhile job of it you would need access to an anechoic chamber, which would be quite costly, and it would also be pretty time consuming

Swolephile 02-18-2015 02:30 AM

What will the price be for the 708i?

dan1210 02-18-2015 06:14 AM

Any more news on these chaps? Im in the uk and info is scarce to say the least, i reckon these could be perfect for home theatre (dedicated room)
Price and availability would be nice to know...

beastaudio 02-24-2015 12:12 PM

With the little 3 series priced at $250 and being powered, I am hoping these come in under 4 digits, but I have no clue at this point...

Yeah I'm also really keen to learn how these stack up to the older 6328 and 6332, as well the M2. It's sort of strange but the 6332s don't get mentioned here that often. I would of thought that they would be more popular.

After reading through the papers and spec sheets on it, I am pretty surprised myself as well....

Valentin, in the Audio Heritage thread linked previously posted a link to Dale Pro Audio's 7 Series packages. Here's the basics:

2.0 705i system w/amp: $3222
5.1 705i system w/amp-sub: $10602
2.0 708i system w/amp: $4848
5.1 708i system w/amp-2 subs: $16747

I'm struggling to understand why an amp and in some cases a sub purchase is required for these line of speakers.

Thanks for posting this. With the amps, they are certainly not cheap. It will be interesting to see how the market reacts to these prices.

I would be pretty surprised if it will not be possible to purchase the speakers without amps or subs - perhaps if not initially then at a later date.

12B4A 03-07-2015 03:52 PM

It looks like Full Compass has them priced individually. The pricing seems to be consistent with Dale Pro's prices when you back out ~$1800 for the amp:
705i: $687.50
708i: $1500

Z, what do you mean by "tweaking the anechoic response"? Are you asking if it's active or passive crossover?

I was wondering if they use PEQ to modify the speaker response so that it is flatter in an anechoic environment - just like they do with the M2s. Now that you mention it, I would also be interested in whether the demo used active or passive crossovers and more generally in JBL's thoughts on using active vs passive crossovers in these speakers. Ultimately I'm wondering if paying for the electronics in addition to the speakers would have an audible effect. No doubt that JBL will say yes :D but it might still be interesting to hear what they say about the matter. I'm sure they'd like to sell as many speakers as possible, with or without associated amps and DSP.

Got it. If active I can't see any reason they wouldn't use PEQ on the anechoic response where directivity is constant and the power response parallels the on-axis frequency response. It makes zero sense not to. But I will certainly ask :).

As to passive vs. active, I'm very interested in that question as well. I'm also interested in the role the separate BSS processor plays compared to simply using the DCi amp DSP?

12B4A 03-09-2015 08:24 PM

Might also be nice to ask them if there is a factory that is actually producing these speakers and if they ever intend to sell them. :devil:

Ellebob 03-09-2015 08:44 PM

Active has advantages over passive without a doubt. The advantages are less distortion, decreased attack time, custom crossover integration by using DSP instead of passive components, better speaker protection from being overdriven. The disadvantage is cost in both design and set up. Active requires getting a signal and power to each speaker or multiple speaker wires if the amps are outside the speaker, passive only requires a speaker wire. With that being said it still comes down to design. There are some excellent passive speakers and mediocre active speakers and vice versa. However, if there is the same speaker in active and passive versions I will take the active speaker. But, things are rarely that simple.

audio0947 03-10-2015 07:51 AM

I would be interested in knowing if these monitors even have passive crossovers, I assume not although I would love to be wrong. I can certainly attest to the awesomeness of the passive LSR6332, if you can stand the simple boxy look they are fantastic speakers for medium to large home environments.

guy80 03-10-2015 10:50 AM

I'm eager to read reviews on these (I'm sure the JBL/Dolby demo will be great no matter). Hopefully a local dealer will have some in stock so I can contrast them to the Studio 500 series & 3 series (LSR)

They do indeed have passive crossovers. See the 4th paragraph of

http://harmanprogroup.blogspot.com.a...roduces-7.html

"The 705i and 708i can be driven by a single amp channel or bi-amplified."

Some impressions from a poster on Gearslutz:

These really are extraordinary!

12B4A 03-19-2015 02:35 PM

I've been going back and forth with a salesman for a JBL retailer and it definitely seems JBL doesn't want to sell these as speakers on their own. Given no impedance or sensitivity rating has been published for these coupled with JBL pushing for bundling them with an overbuilt amp and processor, it makes me wonder if there is something unusual going on electroacoustically that cannot be handled without dumping a lot of power in to the box and/or pulse shaping.

Yes of course. We had this conversation at Rilla's so it thought it slightly funny that you ended up with it. I haven't taken a flu shot but one year, and that year I got the flu. I haven't had one since....Regardless, sorry you were too hammered to make the JBL thing.

It amazes me the things that flow off people's keyboards.

Based on the scope of your comment, one must infer that you don't consciously choose to protect yourself due to a rare condition or in actual history of serious allergy to ingredients in the flu vaccine? Rather, you advocate risky behavior.

So, what is your medical training? Where did you go to med school? Where did you do your residence, and in what specialty? Where did you do your fellowship? Are you board-certified anywhere, in any field?

I am not an MD. My wife, however, is. She has Ivy League medical training, and is currently in a fellowship supported by an R25 research grant from the NIH.

As someone without medical training but with a functioning mind, I defer to her in matters of medicine. And her verdict is that it's crazy anti-science behavior to eschew flu shots, except in the two cases stated above.

(Also, as an aside, neither one of us paid for our flu shots; ours were covered, respectively, a research hospital and BigLaw.)

Anti-science in matters of sound reproduction (believe in voodoo wires, DACs, amps, etc.) merely separates the gullible and people with poor critical listening skills from discretionary income. Anti-science in matters of medicine affects human beings' health. The former is merely annoying, when it's not comical. The latter is tragic.

CDC Presents Updated Estimates of Flu Vaccine Effectiveness for the 2014-2015 Season




Flu vaccine did not protect against drifted H3N2 viruses, but protected against vaccine-like H3N2 and B viruses

On February 26, 2015, updated interim influenza (flu) vaccine effectiveness (VE) estimates for the current 2014-2015 season were presented to the Advisory Committee on Immunization Practices (ACIP). The updated VE estimate against influenza A H3N2 viruses was 18% (95% confidence interval (CI): 6%-29%).This result is similar to the VE point estimate of 23%, which was reported in a January 16 Morbidity and Mortality Weekly Report (MMWR) and confirms reduced protection against H3N2 viruses this season. The VE estimate against influenza B viruses this season was 45% (95% CI: 14% – 65%).
I can't go to work if I don't get the flu vaccine. The hospital I work at would revoke my privileges if I didn't get it. They fired several employees last fall for refusing the vaccine. So I got it. And I got the flu TWICE this winter.

So yeah, get your flu shot! :rolleyes:

So, what is your medical training? Where did you go to med school? Where did you do your residence, and in what specialty? Where did you do your fellowship? Are you board-certified anywhere, in any field?

I am not an MD. My wife, however, is. She has Ivy League medical training, and is currently in a fellowship supported by an R25 research grant from the NIH.

As someone without medical training but with a functioning mind, I defer to her in matters of medicine. And her verdict is that it's crazy anti-science behavior to eschew flu shots, except in the two cases stated above.

(Also, as an aside, neither one of us paid for our flu shots; ours were covered, respectively, a research hospital and BigLaw.)

Anti-science in matters of sound reproduction (believe in voodoo wires, DACs, amps, etc.) merely separates the gullible and people with poor critical listening skills from discretionary income. Anti-science in matters of medicine affects human beings' health. The former is merely annoying, when it's not comical. The latter is tragic.

I'm married to a doctor is not a great way to establish yourself as an authority in medicine :rolleyes:.

Yes, there is a potential risk to my choice, and a potential benefit as well. It's all about balancing that risk/benefit equation. I have the knowledge to make that decision and you don't, so it's likely best that you follow the advice of the policy wonks that draft policy that is easy for the masses to consume and fall in line with. I'm sure that our national policy has your individual interests in mind as their ultimate concern.

So yeah, get your flu shot! :rolleyes:

The policy Nazi's have not gone that far at my institution yet, but it won't be long. For now I have to wear a mask when I am in within 6ft. of my patient. No one can point to ANY solid scientific evidence that I am any greater risk to my patient than before they walked through the door of the hospital, but it has NOTHING to do with that. It has to do with this: http://www.advisory.com/daily-briefi...oyee-flu-shots

In other words MONEY, not science.

The science is, at best, weak. http://www.cidrap.umn.edu/news-persp...lu-vaccination

Yes, the composition of the strains in the flu shot every year is an educated guess. And sometimes it will be wrong. So what?

That kind of "argument" is dismissed out of hand by anyone with a functioning mind. In audio terms, it's as stupid as the argument that one amp sounds better than another based on sighted listening with unmatched levels.

Let me put it another way. I had the MMR vaccine as a child, because my parents are responsible and intelligent people. Yet I contracted measles at 7 years old, during a trip to a developing country. It happens sometimes. Vaccines aren't 100% effective, obviously. But I'm not an idiot. I'm not going to try to stop our child from getting the MMR vaccine on or around 12mos. If we failed to vaccinate her, then we would be guilty (perhaps not legally*, but morally) of reckless endangerment.

*yet; while unfortunately I doubt failure to vaccinate will be a criminal charge in the near future, I know of attorneys who are ready to turn a sympathetic plaintiff into a test case to establish civil liability for failure to vaccinate in the event of an outbreak - but morally)

My point is that she's an actual authority (MD with Ivy League medical training, NIH funding, over 20 pubs, etc.) and, by your refusal to establish your credentials it's pretty clear you're not. Since I'm intelligent but don't have the subject matter expertise, I will listen to someone like her who is intelligent and actually has the requisite subject-matter expertise. And I will encourage other people with highly-functioning minds to do so as well.

You haven't established that.

Where did you go to med school?
Where did you do your residency?
Where did you do your fellowship?
Are you currently a board-certified physician?

Answers to those questions establish whether you have actual relevant subject matter knowledge or "knowledge" of the sort the audio wire true believers have.

As for the knowledge that I have, I have the sense and the intellect to defer to credible sources instead of spreading vile anti-science nonsense.

I assume your wife is board certified and has a reasonable number of years of clinical practice in her specialty?

Funny, I sent my wife a screenshot of this thread.

Her reply: dude must be a surgeon.

And she makes a good point. I know a lot of surgeons with tunnel vision, and surprising intellectual blind spots. The only people I personally know who believe in magic audio wires are surgeons!

Also, in re-reading it I noticed a statement that, in its most generous read is profoundly ignorant and may be construed as morally bankrupt:

This statement displays a basic lack of understanding about the nature of public health. The point of mass vaccination has little to do one one's "individual interests." That's a happy byproduct. Rather, it's to reduce the prevalence of disease as a population. So especially for a health professional to take a selfish health choice rather than the choice that's in the best interest of the population...if I write what I think of the thought process that leads to that decision, someone will probably complain to the mods. Also, snide references to "policy wonks"...that's a bit of a dog whistle for certain dangerously anti-intellectual strains diseasing American politics...

At any rate, we're very far afield of the JBL 7-series speakers. However, it's fair to conclude my participation here (until I have experience with the speakers to relate) simply by noting that the JBL 7-series were designed with more appreciation for science than the anti-vaxxers' comments on this thread. They're an interesting design and I hope to hear them someday soon.

You started a discussion about which you know nothing, then proceed to make assumptions about my credentials in a condescending tone that continues even after its clear that I'm the only one of us in the conversation that is in a position of authority about the subject matter.

You've been wrong about every assumption you have made regarding my credentials, my profession, and my position on vaccinations which is complex and based on actual research, not regurgitated nonsense from some "authority" that has no more knowledge on the subject than I do.

Is she's an "MD with Ivy League training, NIH funding, over 20 pubs, etc." code word for, "she is not board certified and has never actually clinically practiced medicine outside her medical school rotations"? I'd of never guessed...

And where did "surgeons and magic audio wires" come from? Try to be coherent.

That was exactly my point. Because of your superiority complex and superficial understanding of the topic my sarcasm went over your head. Arrogant pseudo-intellectual physicians and policy makers have been responsible for many policies for the "public good", such as this one http://www.nytimes.com/2010/10/02/he...fect.html?_r=0. It is group think superiority complex mindset's like yours that leads to decisions and policy like that.

FYI, JBL will not ever sell these in a passive version without the amplifier/processing. When I was told this I was also told JBL has solid plans to make this in to a self-contained powered version.

Evidence that more speakers are coming: in articles, the 705i and 708i are often referred to as the first two speakers in the 7 series. Dunno, might be reading too much into the wording. I suppose we will just have to wait and see.

@12B4A and @Gooddoc , did you manage to get the names of the specific JBL reps who spoke to you?

12B4A 03-26-2015 08:41 AM

I was talking to a salesman at Sweetwater who was acting as go-between with their onsite JBL rep. SW seems to have a solid, ongoing working relationship with JBL so it seems like it's reliable info.

SyntheticShrimp 03-26-2015 10:41 AM

Why are JBL Pro dragging their feet so much with these? I am interested in a few, but not without more info.

I won't post the names of the folks who tell me things like that. They are not reps but are in the JBL organization in various capacities. The reasons I talk with these folks are related to my M2's, I only ask in passing ways about the Series 7 speakers. And clearly I have received casual answers that can't be relied upon as any kind of official statements from JBL.

ValentinR 04-16-2015 04:09 PM

i fell for that one fore a little while

Why would JBL do that

The LSR 7 series will be sold individually of course they want to match and bundle them with crown and BSS

In the studio businesses and post production it is a good idea to have a DSP to get the excellent results with every speaker in the system
Room acoustics and positioning can really screw things up and a good dsp match with excellent dispersion characteristic of the M2 and 7 series is the frosting

the new crown drive core DCI network amps have a lot of power in a very compact factor (8 x 300w 2 rack space) and you only need 1 Ethernet cable to connect between dsp and amp or amps that a lot of savings in cables and make the system easier to install

of course you may or may not like Crown amps ore BSS

i assure you will be able to buy the 7 series without the electronics

its just maketing stratergy but time will tell

If anyone is interested, Full Compass has the lsr 708i in stock for $1500.00 each.

DotJun 05-30-2015 12:07 PM

IIRC on average, people only get the flu once every 5-10 years and everything else is just flu-like other things.

Anyway, back to speakers! I heard the 705i this weekend at T.H.E. Show in Newport, and I'd have to say they were the most impressive speaker I heard that day. I'm not saying they were the best, as there were some giant horns I liked better, but these were easily in the top 5 of the best I heard. I still can't believe the huge wall of sounds these little things put out!

If only they could be purchased! ;) :)

I'm patiently waiting for my dealer to get stock. I can't decide whether to use 705's or 708's for side surround duty. I'm concerned about the output of the 705's at reference level though. Not sure why the specced them so low. They would have been better off sacrificing some of the low bass output for some more headroom IMO.

I guess if they are run active they could be tweaked for a bit higher output at the expense of bass extension.

Not sure how I missed this, but nice setup! What exactly did you do with the ceiling there? It looks like primarily diffraction? I like it and would love to do something about the ceiling with my M2's.

Also, what speakers are in the middle?

Great to read your comments. Were the 705s part of a surround setup and what were they playing? Also, are the 708s there as well? I'm wondering if you heard them whether they would make it even further up your top 5 list? :)

Nope, they took down everything and put the 705s as stereo mains to show what it could do. I was simply amazed at the quality of sound coming from these tiny speakers. I couldn't find it, but I sure hope there were subs there because I just can't image those little guys producing the bass I heard also.

There were 708s there, as well as m2's and everests, but when I showed up they had just finished putting the 705 up as mains. Btw, those amps they used were not only huge, but very intimidating visually as well!

I'm bummed that I didn't get to hear the other jbl offerings. I can only imagine what they must sound like after hearing the 705s.
@Gooddoc , I don't think they'll have problems at reference. They didn't have it quite there for the demo, but they were still playing at a good clip. If only I had more than a pair of kidneys so I could afford to get those everests.

Thanks. Yeah, this is a tough call. I'm generally one to go on the overkill side of things when it comes to my audio and the 705 is in the "just enough" category so I'm having a hard time committing :D.

Well of all the possible reasons for lack of supply, this is certainly a very positive one. Looks like JBL may have misjudged demand. People who already own these or use them regularly at work need to start posting their impressions... As far as I know, to date, very little info on them has appeared on Gearslutz, for example.

These were initially supposed to release in January. So clearly there is some issue, whether it's supply chain or design change issues is impossible to know. But clearly there's more to it than an unanticipated demand issues. I just hope they have it all figured out at this point :).

Buyers remorse? Sorry, I can't remember your whole system. I know you've got the OS :), but what is the buyers remorse?

I'm thinking of just putting 6 of the 705's in an Atmos 5.2.4 configuration along with the M2's and forgetting about it. I'm thinking you might be saying that would probably be a good thing?

I think you probably got at least a close fascimile of the M2 with the 705's, at least from a pure SQ standpoint. But judging a speaker at a show is absurd. It takes a lot of listening to truly judge a speaker, particularly a very accurate one. The more accurate, the more chameleon like a speaker becomes, and you end up judging the unique recording attributes more than the speaker. The less accurate a speaker and you hear more of the the unique speaker attributes, not the unique recording attributes.

They told me two weeks last week. I can't wait either. I currently have no surrounds at all.

syswei 06-10-2015 08:16 PM

Seems the 705i is limited in SPL because of the 5" mid/bass driver. But the 708i is limited in dispersion in the upper midrange because of the 8" mid/bass. So I really hope JBL eventually introduces a 3-way with the 7-series technologies. Something along the lines of the LSR6332, which has a 5" mid and a 12" woofer. Or maybe something with a 5" mid and dual 8" woofers.
