Yea I don't have tons of headroom down low there but I'm okay with that. Part of these amps tech is the efficiency for bass frequencies so it's a good match. I could end up capping them at 20-25 for movies anyway with my plethora of woofage handling ULF. Music, they are perfect amps! noise floor is damn damn good with RCA and inky black with XLR. Noise floor was one of my main criteria for an amp as I want to shoot for a noise floor in the mid 30's in my dream room build And don't forget the silky chocolate milk sound quality
Ha! Wow, I missed that they are that sensitive above 44hz. I'm not surprised though. Yeah, I would say you are good to go.

"The short term output bursts were taken at a distance of 4 meters where little if any compensation would be needed. Since the 10 meter sensitivity measurement is the more representative measurement of the 215RT�s true output we will look at it to gauge the 215RT�s sensitivity with a 2 volt input. From 44-135Hz the 215RT�s sensitivity is between 100-102dB which is quite good. Below 40Hz the response gradually rolls off towards 16Hz where it the drops off more dramatically below the vent tuning. The 2 volt sensitivity is still hovering near 90dB down at 21Hz. Overall the response shape should match up quite well in a typical room exhibiting a bit of boundary reinforcement of the deep bass. It is entirely possible the overall response shape could extend relatively flatly down into the 15Hz range in room. At the top of the woofer sections bandwidth it can be seen that the low pass filter is in line for these measurements. "

As far as a blind shootout I'm not entirely super motivated to do it but would participate and possibly coordinate and host. I just don't know if I will have the best room for couple years. But we do have 4-5 of us within a few hrs of each other with JTR's. If for no other reason than to get together as fellow enthusiasts and have fun nerd-ing out why not? If you don't want to participate or lug your D-sonic around no worries I should have a Hypex NC502MP module based amp at that time as well. Would be cool to have a Pascal module amp too though!
There was an improvement going from the Inuke (I paid more like $400 ) to the D-Sonic but it was my subjective impression only. You are diving into the deep end in trying to understand the science behind the subjective and I like that but personally don't have the time or inclination. That doesn't mean I'm not up to a GTG as they are always interesting and fun and I bet we could talk Jeff and DesertDome into coming out for a couple of days. Are you still in Eugene or have you moved to RB. I hope you're still in Eugene as it's supposed to be 111° in RB today and that's not Eugene weather ... is it.

I never noticed a difference in the sound between the 5 or so amps i had powering my JTR stuff over the years. Love the dsp feature on the iNukes. Makes for easy tweaking.

New price of $7000 for all 3 of my JTR 215RT speakers.

Could someone measure their 215rt and tell me the distance from floor to bottom of first driver. Need to know for my at screen. Thanks

Just measured, 24" from the floor to the very bottom of the first driver.

I am not looking forward at all to getting these 3 JTR215RT's from the basement to the garage to pack them up.

Do any of you have vaulted ceilings?
We are in the process of building out a mixed use media room above our garage.
The room will be 22'x19' and will have a 16' high ceiling on the right side wall and slope down to an 8' ceiling on the left side wall.
What would you recommend for in-ceiling speakers for Atmos? (would you install 4 or would you do 6 in case more can be incorporated in the future?)
I would need something that is able to be aimed and have read good things about the RSL e34c, but I'm worried about the sensitivity difference between the RSL's and JTR's.
Volts have a higher sensitivity, but aren't able to be aimed.

WTB - JTR 212HTR (2), JTR 210RT (2), or JTR 228HTR (2)
Media Room Being Built - JVC RS500 PJ, 130" Dalite JKP 1.3, LG 65E6P OLED, Anthem MRX 1120 AVR, JTR 212HTR, 6xJTR S8, 2xSeaton Submersive HP, Panasonic UB900 UHD, Dune, HTPC, D-Box
Family Room: Sony HW50 PJ, Marantz SR7010, Martin Logan Vantages, ML Stage X, 4xML Motion FX, 4xML R Ceiling, Outlaw LFM 1EX & HSU MBM Subs, Philips UHD, Dune
