So are "break in" and “biwiring.” The audiophool community has a lot of “regular terms” that are complete BS but appeal to the eyes or to human gullibility. “Timbre matching” is a great example of both! It's facile marketing twaddle whipped up to move crappy center channels. It should be called “timber matching” because the only thing actually matched is the finish.
I’m well aware of Gem2. For a "patch job" they are extraordinary performers, and IMO they look great on the (wickedly overpriced, but pretty) pedestal stands.
This sentence was fine until "because." After that it devolved into speculation. Have you tried moving the man cave speakers into the main room, or the main room speakers into the man cave? What you're reacting to is more likely than not related to the room and placement rather than use of different loudspeakers at the side and rear positions. But you're glomming on the "mismatch" because you see it.
IME the big issue with sides and to lesser extent rears is that sound can kind of "collect" at them, due to the often shorter listening distance as and the greater difference between them with head movements because they’re at the sides. Have you read Chapter 8.5.4 (A "Physics" Problem with Side Surrounds) of the current edition of
Sound Reproduction? If not, you should.
FWIW before immersive my practice was to use coaxes pointed up for sides and rears. That seemed to avoid the most of the problems. With a height layer that approach seems problematic though. About 4 years ago, following guidance from Dr. Toole’s work (
see supra, see also Chapter 12.2.4) I look a flyer on CBT line arrays for side and rear, and find they work really well! You want “mismatched” speakers, try 8” 2-ways with 17mm exit compression drivers and constant horizontal directivity from ca 2kHz up front, and lines of 2” wideband drivers on the side and behind! It worked so brilliantly that in the current home I specified the same, though I went with the 1m tall versions all around this time instead of using the 50cm versions for sides as before, both for looks and because I thought with Dirac ART on the horizon more headroom would only be a benefit
Congrats to your son -- and your bank account for being done with that!
I agree that Studio2 for the fronts (i.e. LCR) would be a better foundation than Salon2+Voice2.
The whole thing about Perlisten's design approach is that they control vertical directivity with the woofer spacing and horizontal directivity with the tweeter array. (One can argue the benefit of that design approach; personally I've been a bit underwhelmed by them every time I've heard them, which has only been a couple times. But lots of smart people with great ears love them.) But if you rotate the woofers to be horizontal...you get neither constant vertical directivity nor smooth horizontal directivity. What you get is instead a dispersion disruption in the horizontal plane because the three tweeters can't go low enough to match the narrow directivity of the wide woofer array, and wide dispersion in the vertical plane until the tweeter array takes over. L
Timber matching, yes. Timbre matching, lol. If you do have to flip a speaker on its side, an coax or an MT array with a 4"+ woofer is better, because the mid can play low enough to keep the side woofers from needing to play high enough for the array directivity to be a major factor. .
Movies are poor source material for evaluating sound quality. Given the dominance of the visual, as long as the audio it's kind of OK, gets loud, and doesn't actively get in the way (
e.g. subs flapping, or a harsh edge at high volumes) it's generally fine. IMO music benefits immensely from immersive, and even more so from properly set up systems with identical LCR, multiple subs with appropriate correction software, etc. That includes stereo recordings, thanks to Auromatic.
That's not the way physics works.
You
can - if you care to! Just move the screen up a little bit. It looks like that screen is under 45" tall, so even if your ceilings are 8' high you can still fit that screen and a 50" tall loudspeaker. Now, if sound quality is not the priority then do whatever. But in that case this is all pretty expensive audio gear.
