The P18 can play these low frequencies at SPL as required for much larger rooms than yours, so you will be over-specced from an SPL point of view. Based only on your room size, I would begin with 1 x P18-FP placed below or behind the screen, powered using our new rack-mount amp, the DA-06 (2 x 1200W) and plan to add a few P10-FP as balancing subs, distributed throughout the room, if required. But before we continue, we need to know what materials your room is made of: timber bats/sheet?, brick?, concrete?
Sorry for the delay in responding - I missed your reply at the time, and only saw it after rereading this thread last night from top to bottom...
I think some mode simulations and desired smooth frequency response over two rows will wind up dictating at least two subwoofers on the front wall. In that case which sub would you recommend that I could use two of on the front wall (behind the screen wall, AT screen)? Seems like that would provide perhaps smoother FR in the room compared to say a P18?
We don't comment on other products. The Procella loudspeakers all use studio-quality, Italian-made compression drivers (HF), mounted on our proprietary wave guides. This gives them much greater SPL than dome-tweetered loudspeakers, with much lower distortion, greater clarity and much better dispersion characteristics. All our loudspeakers are designed to be timbre matched, allowing you to use P28(P860), P8(15), P6(10) and P5 in any combination (LCR, surrounds) as required for your room, whilst maintaining our Identical Voices(TM) principle throughout.
Hope this helps!
Thanks. In my case, I do not need reference levels, so the advantage of being able to play super clean at very loud volumes is a bit lost on me. I usually listen at say -20 dB to -15 dB on the MV. What I do want, however, is super clean and clear sound that is very well balanced. I love the fact that the Procella line shares the same voice and that the P6iw *appears* to be a good choice for 3D audio ceiling speakers, which is more than I can say compared to how other manufacturers are behind in this area.
My main concern at this point about the Procella speakers is that I really cannot imagine what a horn-based system like this sounds like. I've always had soft-dome tweeters. I have very sensitive ears (in a bad way). Loud noises, like a sudden hard clap of the hands, will make me reach for my ears to cover them quite quickly. So if horn-based speakers tend to be a bit more shrill or sharp than the types of speakers I've been used to having, I wonder if that sonic signature would appeal to me. That said I have no idea if the Procella even sound like that - I just have this preconceived notion that horn speakers may be like this - and that notion is likely wrong. But that's what is weighing on my mind. With no great way to audition the speakers, short of getting on a long plane ride, I'm not sure how to proceed.
