Hey all. I'm in transition with gear, setup, etc. Def going to finally do the Atmos transition with 4 overheads. My question lies with heights and wides with Atmos. Is it necessary? I imagine heights no but wides could still have benefit just not sure how much if setup, room treatment is spot on.

Looking for any of your experiences with such thus far. with wides mainly and Atmos...

I have had Wide speakers since 2010. I was previously using them with Audyssey DSX.

Now I have a Dolby Atmos / DTS:X processor and the wides are not used very much with native Atmos content, even though they can be used.

Native DTS: X content does not use the wide speakers either, because there is an 11 channel limit (7 bed / 4 heights), and Wide speakers are not included in the bed channels.

For up-mixing, the Dolby Surround Upmixer (DSU) currently will not “map“ to the Wide channel speakers

The forthcoming sound format DTS: X Pro will eliminate the current DTS 11-channel limit, so the wide speakers might see more “widespread “use. We just have to wait and see.

Any one know what is the dispersion angle for the Slanted 8LPs? I am looking for something around 120 degrees. The obvious choice seems to be bipole but can't find anything with high efficiency...

I believe all of the s8 speakers are 180 degrees.

Looking at some post before I found this info

"The JTR 8's use a custom version of the BMS 8CN552 and have a 90 degree dispersion pattern"

The JBL Control 328 have a dispersion pattern of 120 degrees if you're looking for some atmos speakers with high efficiency and wide dispersion pattern.

I thought 120, either way coaxials cast a WIDE pattern. Is there a scenario where that wouldnt work?

I can't believe how dead this thread is!

The Volt good cheaper option...

Haha, this is funny all the numbers being thrown around. It may be due to the fact that true dispersion of a coax is going to be frequency dependent and you have to look at it really as an average over the higher FR of the driver to even quote a singular number, albeit, this is exactly what most speaker manufacturers do to derive their one-off number for dispersion.

Looking at my pictures above, do you think the single 8 LP work in that application? Wish i could just ask Jeff.

While some wider dispersion would be nice, they should be fine. If you get down the road a little and really want to do it right, get a pair for each row.

Thanks. Since I can’t get a response from Jeff, I am going to compare my current PSA 110SR in that spot and a couple of bipole speakers and see.

215RT for me with 210RT right behind.

I bet the 215RM and 212RT are amazing as well. Basically any of the ‘R’ line of speakers with the exception of the 210RM.

Thank you. I've been thinking about the 210RT recently and wondered how that might sound in a medium-sized room. The 215RT is a monster and might overwhelm me. The JTR speakers are intriguing.

I had the 210RT’s as LCR and upgraded to the 215RT’s. For the majority of music I probably couldn't tell the difference. The 215RT’s go down to 12hz or so in my room so they have a deeper bottom end, but the majority of music doesn’t go that low. The 210RT’s went to about 30hz in my room.

212RT/210RT currently. Only because the horn/compression driver is closer to ear level than the 215RT. Ultimately the 215RT's can outperform the 212RT's. But the 212RT's can get louder if you care to have blood coming out of your ears.

Wonderful offer and I appreciate that. I'm in Ann Arbor, Michigan. I've driven to Madison before and it was a wild ride. Very exciting tolls around the Chicago area. I doubt I'll make it over there but thank you.

I'm very confident that I would enjoy the 210 & 212 in the RT format. I feel good about that. This could happen.

I have the relatively meager Noesis 212HTs. I originally ordered the 228HTs but switched to the 212HTs at the 11th hour because they were the most expensive models on sale last Thanksgiving. Even at the special price of $1599 shipped, it was still a lot of money. One 212HT cost more than my last front stage combined.

Before I received them, I was afraid that I couldn't discern the sound quality from these. I knew they would be good, but just how much better and would it worth the additional cost? What if the law of diminishing return starts at a lower price for me? All of these questions were answered once I hooked them up the first time. The 212HTs are neutral with a fuller sound. The FR measurements at the MLP showed elevated 60~300Hz. Now I am bombarded with mid / high bass from music and movies. Movie dialogues are crisp and schintilating and just hook me to the screen. Sometimes I am spooked by the dynamics or the attack. I listen with Audyssey Flat and the treble is just smooth as butter and never fatiguing to me. I feel like crying every time I hear them. They are worth every penny.

So grab whichever model that fit your budget. If the lower end 2 way 212HTs sound like this, I can only imagine how the 3 way Reference series sound.

For movies only the more discerning ears will be able to tell a major difference between the two, with all the action and stuff typically going on in the movies we all appreciate around here. But once you throw some 2 channel music at the reference series speakers, you really see where the main differences are. Even if you only do music 30% of the time, I'd say it's well worth the move up. Not saying you are Chucky, just in general.

Finally reran Audyssey after installing 4 slanted 8LP's in ceiling and having crossover upgraded in 215RM. Thanks Jeff!

Popped in Ready Player One for the kids last night. Atmos was definitely worth the expense, time and effort. Glad we finally did it.

With the added height channels (coming from 7 channel) I'm thinking I may back down channel levels...it's so much louder, LOL. Not sure if you guys have experienced this or did the same thing.

JTR subs vs "regular" home theater subs?


Hi guys...

So I've been hearing great things about JTR. I've never highly considered them...due to size and space constraints, and money contstraints.



But the entry level Capivator JTR 118 is a possibility for me Given that it costs around $1800, it is in the same realm as an SVS pb4000, or similar enthusiast subs.



How would the JTR Capivator sound vs a comparable SVS offering? Or how would it compare to a top of the line HSU vtf-15 mk2?



Is JTR in a different league all together? Furthermore , could it be used in a regular living room?

So last Saturday night after watching Bumblebee (a pretty decent Transformer movie, BTW), I was going to cover up my JTR speakers as usual. Yes, I cover my JTR speakers/sub with plastic bags/sheets when not in use... Then I started wondering how in the world the Noesis 212 could weigh 125 lbs... that's even more than almost all 15" ID subs... Therefore, I carefully opened one up just to see what kind of magic dust Jeff put into his speakers...


One 12" driver removed, revealing a huge crossover board and cotton/denim sound damping backing...


Another angle showing there were 2 crossover boards...


The 12" drivers looked to be Eminence KL3012CX-8s...


The crossover boards were as wide as the woofer. Look at these heavy duty caps and resistors... I put a can in the speaker for scale...


The horn loaded B&C DE990TN and the 3" cotton/denim sound damping in a cabinet made of 18 ply void free Baltic Birch plywood. The extensively-braced cabinet would have been heavier if MDF were used.


Let's take a closer look at the first crossover board... Metallized polypropylene capacitors (made in France), perfect lay air core inductors (made in Canada), and wirebound resistors by Solen.


Crossover board No. 2 (Yes, there were 2)... More Solen capacitors and iron core inductors. Too bad I do not have a backgound in EE...

I have nothing but wonderful things to say about how my Noesis 212HTs sound. Now I see all these goodies inside a lower end JTR speaker. IMO, if this speaker were offered as a kit on DIYSOUNDGROUP, it would likely be priced at close to the $1899 JTR retail price.

I think I am better off enjoying them and leaving the speaker making to Jeff.

I can’t imagine what these sound like given I am blown away by my PSA MTMs.

Hi guys...

So I've been hearing great things about JTR. I've never highly considered them...due to size and space constraints, and money contstraints.



But the entry level Capivator JTR 118 is a possibility for me Given that it costs around $1800, it is in the same realm as an SVS pb4000, or similar enthusiast subs.



How would the JTR Capivator sound vs a comparable SVS offering? Or how would it compare to a top of the line HSU vtf-15 mk2?



Is JTR in a different league all together? Furthermore , could it be used in a regular living room?
The 118 uses a pro style woofer, will have a diff sound characteristic to it. Lower moving mass and higher sensitivity, lower 2HD. Seems more are moving to pro style woofers for this reason. Many of them being tested on Data bass lately. You will sacrifice the ULF but it also seems that craze where everyone thought they needed to be flat to 5hz in room has faded. I would see if you can find anyone close that has some pro style woofer setups, most likely a DIY but you can hear what lower 2HD sounds like. Not everyone likes it, 2HD is not offensive like 3HD so some actually prefer it.
