Wait. Don't mixing stages have multiple surrounds on each side? Left surround is a mono signal. The multiple speakers will add together pretty much at any listening position although distance from...

It is about mixing and mastering. We cannot remix or remaster the media we buy. It will have the dynamic range that the folks who mixed and mastered gave it, and all we can do is set overall...

FWIW, AFAIK, the basic answer is that there's not a crossover available for the LFE channel. I don't happen to notice localization with my sub but it's on the front wall about a third of the way...

The thing about speaker power compression is that the amplifier cannot see or feel or smell or taste it. So if my speakers hit 95 dB at 10 watts but have 3 dB of compression at 105 dB, they need 200...

FWIW, I ended up strongly suspecting that my "directional" corner sub issues related to resonance(s) in the adjacent window, walls, or something. Getting it out of the corner was the easiest fix.

+1 to all. the phono cartridge output also absolutely must have the RIAA EQ curve applied to it, or it'll sound really wimpy (that's part of what the phono input does). The whole RIAA thing is...

how come I can't see zero, then, since it occurs exactly as often as the peak? We don't hear either the zero or the peak as the sound level. They last, at most, in the audible band with a pure sine...
