They do, but the "trickledown" is essentially limited to the waveguide from what I understand. They do have the advantage of being quite inexpensive.

The newer LSR705 and LSR708s are going to be much more direct "trickle down" versions of the M2s, as they share much more of the M2 technology. These are not yet shipping, but will be soon (Gooddoc can tell you all about the wait for these). Supposedly there are some early release versions floating around.

Not only that, but about 80% of movie soundtracks are mixed using JBL speakers and about half the music recordings. If you want to hear what the mixing engineer intended, you have a much better chance of that with JBL than any other speaker.

I actually came to that conclusion after getting my Studio 230's. I like to download tracks from engineers that I know use JBL's in the studio and they just sound great on my desktop system.

Howver do you think that would apply to other Harman speakers as well, Infinity or Revel?
What about headphones?

Revel utilizes a great deal of the same R & D as JBL and I also know that Revels can often be found in mixing rooms (there are several prominent film composers that mix on the Salons). Both brands have the same heritage as far as rigorous scientific testing and a desire for extreme sonic accuracy. The main obvious difference is that JBL uses horn drivers (for the most part) and Revel does not. Interestingly, several JBL Synthesis systems have Revel speakers included as part of the entire system.

I am not nearly as familiar with Infinity these days, so hard to say.

For headphones, the Harman brand is AKG. I have a set of K240s myself. Harman just recently did a bunch of double blind testing of headphone designs and the results are reflected in the new JBL line of headphones. They look like modded AKG designs to me. Sean Olive wrote about the headphone testing done at Harman on his blog:

As mentioned, you're missing either a center or a 5th satellite.

There were quite a few of those type HT setups sold over the years. You might see one like it on eBay at some point. Most of them have "SAT" or "SCS" in the model name. 125SAT, SAT300, etc.

Probably a good question for the appropriate Onkyo AVR thread.

I have an Onkyo AVR, but Im not familiar with that specific model. Did you reset all your internal AVR levels to 0 before donig your test? Are you using Audyssey? I suggest you to look the Audyssey thread (and read!), or read your AVRs manual.
Good Luck!

Thxs everyone,I did ask in the Onkyo thread no one answered I guess I'm inpatient! Read the manuel didn't say anything about test tones or level,the avr doesn't have audyssey its a Onkyo tx-nr646,I thought maybe it was because of the size of the JBL

You're asking the wrong guy. I admit I'm still so googly eyed over the M2's, even after almost a year with them that I warn you that I can't be considered an objective opinion . Seriously, the owners bias Force is strong Luke.

But, yes, I have listened to the LSR 305's since I have a friend who has them. They sound very good and are certainly an absolute fantastic bargain IMO.

Onkyo 646 is a new model. Im not familiar with AccuEq in new Onkyo models.
Speakers size is not the cause for your problem. I suggest you to start all over again.
Read Chapter 1 in the Initial Set-up, page 12 of your OM.
Check your speakers are connected in Phase.
I dont know if AVS have a specific thread for that model, maybe you can check that too.
Be patient!

I'd be VERY curious to hear how JBL's own high-end "PA" speakers compare to their Screen Array cinema line....

JBL SRX835P
15" Three-Way
Bass Reflex Self-Powered System



http://www.jblpro.com/www/products/p...p#.VawtiBOqpBc

I currently run three KRK 10-3 active mid-field monitors with a Marantz AV7005 pre-pro and absolutely love them.
But for the next upgrade into a bigger room (combined theatre & Edit suite), it'll be about theatrical-size sound - and accuracy!
It'd be great to keep running XLR and not have to buy separate power amps & speaker cables again.

Finally after many year of searching my setup is allmost complete. I just got my Ti2K's and its time to finalize an Auro 3D 10.1 setup


Speakers:
- Sub REL Q150E
- Fronts: JBL Ti6K (currently repairing cross over due to burnt tweeter and at least a resistor burnt (infinite resistance), measuring capacitors next)
- Center: JBL Ti1K (not as good as the Ti6K or2Ks so I am wondering if something is wrong but it has been like that since i bought it 10-15 years ago, speech is muffled in comparison)
- Rears: JBL Ti2K (finally found a pair that had been refurbished, tweeters and one of the bass/mid, so they dont sing alike yet but oh do they sing regardless original stands as well )

- Front high: 2*JBL XTi20 (titanium tweeter from same company and tonally not that different from the Tiks but of course in a different leauge when it comes to clarity, sound stage width a.s.o. but for the 2nd & 3rd layer I think they will be.more than enough)
- Rear high: 2*JBL XTi20
- VOG: 1*JBL XTi Centre

(Wide: JBL XTi 20 (got those before the Ti2Ks and thought I could run both Auro and Wide but nooooo not even by switching modes, have to recalibrate for that...hmm... )


Feed:
Pre: Marantz AV7702
Amp: Emotiva XPA-5 for fronts (the Ti6Ks went from allmost non existent bass to super tight pump when moving from below amp to this one in bi-amp - oh man they need power to wake up, but what an awakening)
Amp2: Denon AVR-3805 7 channel reciever used as amp for the rest until I have tested out the system for power needs. Since Auro is full range and the XTi's likely need loads of power as well ill probably go Emotiva 7ch


So the last thing on the list is of course the JBL TiK sub.
I recently missed a bargain from Denmark and then jumped the boat on a little bit to expensive piece from Holland (shipping that heavy piece is not cheap ) so still looking around in Europe


When I bought the Ti6K I compared for over a year with Infinity Kappa 600, Audivector, Canton RCL and basically all brands I could find in the same league but the sound of the Tiks just blew me away and the design certainly did not make the choice any harder. If its any equipment I am afraid to break its the TiK range. Sure it can still be found but it is damn hard (too me a year to find the 2s) and while I found the tweeter domes from a french company a couple of Years ago I dont know if how long that will last. Bought 3 extra just in case (they were quite cheap anyway and most sensitive of the elements, for sound spikes...and kids )


As I have torn out the cross over (messy work) of one Ti6K I thought I would try an upgrader of the SCR capacitors if they are blown.
From what I read there are way better alternatives for a decent amount of cash. The treble is allready awesome and super detailed but if it can get better then why not


When it comes to Auro 3D I am not sure wether I should timber match the fronts (Ti2Ks as front high) or if I should match the 1st layer (having the Ti2Ks as rears). Have anyone tested those combos?


Have a nice summer JBLers =

Nice setup. As rare as the Ti-K series is in Europe, its 10x more rare in the US.

Not really. If you feel a need for more power to the main speakers, get a separate amp for them.

Funny thing is, I also bought Klipsch in 85, and they have never failed. listening to it as I type this. So here are the statistics.

JBL L380 - 3 surround replacements, needs a 4th
Heresy - hasn't needed anything in 30 years

You do the math.

I have set my AVR's volume limit to 80; is it ok for the JBL speakers? Is there any limit ie, how much input my speakers can afford?

You do the math.
Your JBL B380 (not L380) is worth as much today as when you bought it, assuming good condition. That's pretty good math.

Check for the recommended power amplifier for the speaker model you have. If your amp has not more power than recommended, the limit will be, when the sound gets distorted....
Until that happens, enjoy....

The surrounds have been replaced 3 times by authorized JBL service center, so what I have paid for them, including 3 x the money wasted on fuel, labor, parts, and perspiration is alot more than they would resell for after a 4th go.

I thought it was my fault the surround failed the first time. I had this paired with a bridged NAD 2200, fed by a Hafler preamp and JBL's own BX63 crossover. After the 2nd failure I began to get suspicious as the sub sat unused in a climate-controlled storage. After the 3 replacement the sub sat in my living room without a decent amp to drive it, so again saw little use. The surround is tacky now, you can't touch it without taking some with you. I'm so disgusted with this POS.

You do the math.
Yes... I remember that L line well. Not exactly JBL's finest hour.
They seemed like a good idea at the time...... until you listened to them!

It seems JBL could have done some research on longevity or improve their components. It makes me steer clear of anything JBL.

At age 53 and two heart attacks, I am no longer able to lug around a 15 cubic ft. piece of furniture. It sits useless in the corner, an expensive lamp stand. Once again the surround is there for show, if you touch it, it comes off on your finger.

Funny thing is, I also bought Klipsch in 85, and they have never failed. listening to it as I type this. So here are the statistics.

I understand your frustration, but lets put it in perspective. I had Chevy cars back in the 80s that were junk and today are a total POS. That doesn't mean the new vehicles are bad. In fact, they have better performance, safety, fuel economy, and emissions than they ever had. Should I not buy Chevy because my old Camaro fell apart 30 years ago?

The newer LSR705 and LSR708s are going to be much more direct "trickle down" versions of the M2s, as they share much more of the M2 technology. These are not yet shipping, but will be soon (Gooddoc can tell you all about the wait for these). Supposedly there are some early release versions floating around.

As an owner of the 308/305/310s 5.1 combo, I will say this, if I could do it over again, and get a passive version, I would. Right now the main thing holding me back from going an Atmos or DTS:X setup is because those with pre-outs cost like double the price. I love having powered speakers with individual volume controls and not having to worry about amps / etc. But the Atmos expense is ridiculous.

Anyone wanting to get into 3D sound cheaply should go passive, I think, especially for height speakers. But the main hindrance is the added cost for AVRs with full pre-outs. It's ludicrous how much they are being overcharged. The money I saved on the 308/305s from other speakers I was considering, is wasted due to my having to buy baluns and the extra cost of pre-outs. So absurd. I wouldn't recommend it.

The 700 series, being passive, is probably a much better buy / safer bet for Atmos / DTS:X setups. It's a bit too late for me now, but I really wish I had an Atmos upmixer for all the legacy content I watch. It might be cheaper for me to buy a low end Atmos receiver with speaker-level outputs then a speaker-to-line-level converter for all channels, than it is to get an AVR with pre-outs. Seriously, it is that expensive. Plus most of the lower end full-preout models only do 5.1.2 at most. It sucks. To get 9.1 pre-outs you gotta spend at least a grand and a half or something like that. Doesn't really fit in with the concept of saving money to get really good powered speakers, does it.

Did you really need to buy the unbalanced to balanced converters? I was having some SPSU noise and ground loop hum issues with my 305s. I already had some Jensen line transformers lying around and they did help with the problem. However, when I put the external RAID and LSR305's on cheater plugs, everything went silent except for the low level hiss that's inherent to the internal dsp/amp. I'm now running RCA to XLR cables from my AVR. Cheater plugs are 2 for $2.
