I agree. We all gathered Sunday night for the AMZSPM2 and I stopped it 10 minutes into it and level matched the LCR as the dialog in the center was killing me. I was getting some dirty looks from the crowd because of the pink noise, but had to be done. Of course I fell asleep 10 minutes later, but it sounded much better for that 10 minutes.

Yep, the margaritas were the salve that kept me from diving into the problem. Well, that and that fact that I had already seen the movie 3 times.

Yes, those damn HT chairs put me to sleep even when the movie doesn't.

RMAF 2014 - A little background: Last year I contacted JRiver Media Center and offered to host a room at RMAF 2014. They were interested and said to go for it. Of course a room needs speakers. I contacted Jeff and he was interested in bringing a new speaker design he was working on. As we now know, that turned out to be the 215RT. The rest of the equipment/gear is all stuff that I'm bringing.

I've got the following so far:
  • Amps: 3 Digital Amp Company Cherry Monoblocks and 1 Cherry Jr. stereo amp for a total of 5 channels
  • Power: Torus RM 2.5 Power Isolation Unit
  • DAC: Lynx Aurora 16 Thunderbolt
  • Source: HTPC - I'm building a new Windows one with a motherboard that supports Thunderbolt, Linux NUC
  • Control: Ipad, Android Phone, iPhone, tablet, laptop, and keyboard
  • Monitor: 27" LCD
  • GIK Acoustics Room Treatments: two Tri-Traps, two 244 bass traps, two 242 acoustic panels

I also want a MacBook with Thunderbolt port.

The complaint I see most often about rooms at shows is that the acoustics are terrible and no treatments are being used. I hope this room can be treated to let Jeff's speakers sound the best. I may be able to borrow some more GIK Tri-Traps (4) and diffusors (2) from a local friend. Chris Seymour/Seymour AV has offered an AT screen, but then I need to get a projector. The AT screen would fit between the mains, but cover the center speaker.

How would you setup the room?
Anyone want to design a flyer and banner for the JTR Speakers 215RT?

JTR Speakers will be just down the hall from Wilson Speakers and GR Research.

Here is the room size:

So if we were to by theory double the wattage to 1100watt that would add +3dB and if you were to say add a second driver also with 1100watts you'd gain about +6dB for a total of +9dB. Which would roughly have the same output as the 2400watt SubM HP. So take a look at the numbers of the XS15se and compare them to the UXL-18 and it's down about 9-10dB's compared to the UXL.


So I would have to think an UXL-18 would be very close in output to the SubM HP, but again that's just a shot in the dark....lol


What theeeeee heck?

Are we playing 6 degrees of Kevin Bacon?

A lot of times JBL 8340 pro stuff is what people recommend, well I think I have found another excellent suggestion for guys to use. Reaction Audio's CX-10 10" coax speakers, they list them as an LCR speaker but it could easily be used as surrounds. I was actually a little shocked to see the components used in this speaker too, after talking with Jeremy from RE I discovered that they are using a compression driver that closely resembles the Radian 475pb http://radianaudio.com/product/745pb/ and the 10" driver is basically the http://www.usspeaker.com/radian%202210-1.htm and has a $150 custom crossover in it, all for only $599ea shipped. This appears to be an excellent price given the components the RE is using.


And to top it off after a few back and forth PM's with Jeremy, he's going to build me a surround speakers using the Radian 5208C 8" coax. http://radianaudio.com/wp/wp-content...2/5208C-e-.jpg which is a very nice coax. He's going to build me a slanted style ported cabinet with a magnetic grill cover in a satin black paint finish like the subs they build. They will be sized right around 13"x13" and at top 9" deep and I've asked for a 20 degree slant. Pricing is basically $500 shipped. Seems very reasonable and I'll have the first pair that they are building.


Like I said just thought I'd let you guys know because I know how many times guys post questions about what surrounds would work well with JTR mains because they can't afford to buy the S8's or Slant 8's like myself.
Your post got me really excited about this project. I assume that's $500 per speaker. Is he open to doing more after your set? Keep us posted...this maybe my next purchase...can't quite swing the full price of the slant 8's but would like to look for an alternative to my JBL 8340a's.

Thanks very much for sharing this awesome discovery.

Yes $500 per speaker and he will be offering this speaker for other people to buy after my set. I know how you feel, I would love nothing more then to buy two pairs of Slant 8's for my room too. But just can't justify spend that much, after all this is a hobby and not my only one I understand why the Slant 8 is priced the way it is though, as it uses a very high quality coax that costs around $500ea and then you figure in a cost of probably a $150 for a custom crossover, speaker cabinet and putting a finish on it. Plus Jeff needs to make money, so certainly not trying to say they aren't worth that. Just that I can't afford it and I think I've found an excellent alternative for guys looking to spend a little less.


I should have a sketch up of it by next week, anyone that's interested can pm me and I can send them some more details.

My Gear:

JTR Noesis 228HT (LCR)
Axiom Audio QS8 surrounds
Sherbourn PA 7-350
Pioneer VSX-21TXH
JVC RS45
Falcon Screens FVHD105
Dual PSA XS30's (gone but not forgotten)

I am not sure. It would be the in the NE GTG Heavy weight GTG results thread if there is anything. Not really a shootout, just opinions. The real show was down stairs.

Yea, slick little unit for sure. I am contemplating getting one of the open DRC's with the dirac stuff to be able to use the EQ for all sources. Dirac by all accounts seems to be one of the most versatile DSP engines out there. Trinnov is another good one but there is no good implementations of it at this time for less that something like $10,000....heh, NOPE.
