stereo bass query.

tade · 23rd February 2006, 01:52 PM

I know these will be a super simple questions for someone who knows the answer; at what frequency will my two subwoofers start to act as a line array and get an efficiency boost if they are X feet apart? Do I have to worry about any comb filtering or any nasty effects like that? are two subs better than one in terms of room interaction and imaging?

Thanks

Supposedly two drivers complement eachother best if kept within 1/2 wavelength at crossover frequency. Calculate wavelength using speed of sound / frequency.

The subs will couple when the distance between them is half the wavelength or less.

When positioned correctly 2 (or more) subs should yeild a smoother response than one.

awesome, thank you so much.

So fi i space them at ten feet, I should get a boost at around fifty hertz. I plan on using reletively small boxes F3 around thirty, so this should help. Of course I suppose at those frequencies the sound in my room will look like the sruface of a kiddie pool so...
Thanks for the help.
