If bass is localizable to the sub either the sub is too loud or it is in a bad location or crosssover is too high. I cannot put my sub in the front right corner because it is always localized. ...

as attractive as this idea is, I eventually figured out that Ohm's law (an actual physical law of the universe, like gravity) means that a more powerful amp cannot do anything different at any given...

The amp multiplies the incoming voltage. During silence, if its multiplication factor is thirty, the amp puts out thirty times zero. Zero, iow. The bigger (louder) the incoming signal is, the more...

50 is not halfway up. The volume readout is in decibels. Every ten dB is about twice as loud and ten times the power. So if i counted my fingers right you are at 1 100,000 of wide open power at...

The marantz might have a baked-in warm EQ curve. Or it might have been designed to be linear but component drift has created a non-flat response. Or possibly it is distorting euphonically atypur...

jbl specs those horns down to 500 Hz and recommends a 500 Hz or higher crossover. Possible that in your room your bass bins are 3 dB below the horns at 120ish Hz. Audyssey is looking for the point...

BD can, of course, produce bass just as well as "more lossier" DVD soundtracks. So the question becomes whether the soundtracks are the same. Not always. The most famous example around here is...

the avr presumably has analog inputs, so it doesn't need to digitize analog. Most just take the analog inputs and use that. Your setup, which I admit has me slightly confused, is unusual.

If asymmetrical waves have an unavoidable dmc component, a point I don't concede, at least yet, the clipping only increases the dc component. It does not create it. Asymmetrical is asymmetrical. ...
