>i paired my huge speakers with a sub and it was a bitch to get the right room placement for
if it's that hard, you have big modes problems, and there is NO right placement
reminder that modes are 20-30dB huge probrems (and you can't get out of bigger than 3-5dB probrems with equalization without sharting everything even worse)
and that each time you add 10dB, you feel it as twice as loud
which you can either start solving with:
- absorption 1/4 of the wavelength thick (which at 20Hz is 4.3m/14ft: thick & sic)
- many subs (think 4-8 subs, and in a not so bad room already), whose placement you'll have to simulate (with carefully managing the delay) to densify the modes (because once modes are close enough to one another, you don't hear them anymore, on top of them being weaker at higher frequencies, hence why modes are only a problem at low frequencies, given some Schroeder's frequency/room size: lower/bigger is better)
and that's without even talking of first reflections (speakers shall be encased in insulation, and the corners next to them shall be eaten by absorption), general, reverberation time (which shall be a lot fucking smaller than most would think they'd like), tall ceilings (under 3.5m/11.5ft, before absorption, it's gonna be hard), predictable wall impedance (hence why the box in a box, foremost), etc
I'm not telling 90% of budget into room treatment out of spite or snobiness: it's just I've forgotten more about physics acoustics than most will ever learn (and I'm not even bragging: many are much better than me)
>everything is away from walls
that doesn't fix shit in an untreated room
wall placing only allows free dBs (6dB in a corner, and 3dB against a wall: for uncorrelated signals, so a bit less in practice)
which is very useful to reach required SPL
encasing also avoids weird first reflections, but not at frequencies that matter at all for subwoofers (they shall very much be encased in treated walls, ideally: all speakers should)
