Pro Audio Technology speakers

In wall AV loudspeakers might be a little outside the knowledge base of most here on an audio forum. Not sure what forum you might seek out but a group that deals in AV stuff. 

Thank you both for your thoughts.

The SCR-2215sm does indeed look like a beast! I am aware of the Hales pedigree, which makes me feel somewhat better. I will look into JTR, too. re: the sub response, units like the SVS PB16 Ultra claim response +/- 3 dB down to 13 Hz...supposedly that very low response is an important part of the "feel" of the sub.

Russ, fair point. This forum has already provided me such excellent info on other topics that I wanted to get any input from the folks here. I find the quality of discussion to be a bit better than elsewhere. But I will look for other places to post as well.

Your installer is right on the money this along with procella is the best for building a true theater

@audiotroy -- yeah, from what I've been reading, I'm pretty sure this would be a great theater system, although I'm not sure how I feel about the tight coupling of the speakers with their DSP amps and the bi/tri/quad-amping. I'm less certain how suitable the system will be for music only applications. Any thoughts on that? I would not say I'm a super-critical listener, but I do want to make sure music sounds great.

@txavgut --

The system will be used 50/50 for movies and music. [...] the subs (LFC-15sm) don’t seem especially impressive, claiming response only down to 20Hz. But I realize specs aren’t everything.

If used 50/50 for movies and music a 20Hz hard deck might be a very appropriate compromise. A lower tune affects bass presentation, and while depth-wise it will reveal infrasonic information found on the source material from select Blu-ray and 4K UHD titles, it also has impact on the central to upper bass character and therefor potentially, depending on the chosen cross-over frequency, the integration with the main speakers.

I like crossing over to the mains fairly high (~85Hz), while not least high-passing the main speakers at the same frequency to relieve them from the lower to central bass, which then cleans up their upper bass to lower midrange and adds further headroom. Similarly, if one would, I prefer not to run the midrange/HF horn + compression driver down to their lowest (professionally) recommended cross-over frequency, but just enough above it (with high-order slopes) to clean up the sound bit and aid energy-coherency (that’s the term again - energy coherency: in combination with phase and timing behavior it’s vital for music reproduction to create a smooth sphere or "radiation bubble" of sound in front of you).

Honest 20-ish Hz extension at close to war volume, still effortlessly reproduced, is something that won’t be easily forgotten, and makes sub 20Hz extension that’s any less capably reproduced (i.e.: that takes loads of displacement area, btw.) seem kind of blah and not worth it. Just my $0.02..
