Re: Subwoofers vs budget... where do you draw the line?
If I have DI-matched two-way speakers, I always start with flanking subs. I mean, you can run the speakers with no subs at all if you're making an apartment system or something like that, but if we're talking stepping up a notch or two, start with flank...

Re: Flanking Subs vs Helper Woofers
Can you explain what the decorrelation filters are, how they work, how effective can they be in multisub and what kind of processors are used to make them?

Re: Flanking Subs vs Helper Woofers
Flanking subs and distributed multisubs are different animals. They have a similar purpose and correspondingly similar execution but have some specific differences because of the frequency ranges where they are intended to be most effective. Flanking s...

Re: 3pi, smaller cab possible?
Changing the size of the baffle will alter the speaker's directivity at low to midrange frequencies. At low frequencies, the speaker radiates omnidirectionally but as frequency rises, the baffle begins to limit the radiation pattern to the forward-facin...

Re: Flanking Subs vs Helper Woofers
If flanking subs are designed to address boundary interactions and room modes only in the 80Hz-200Hz region, can "mid-bass" bass-reflex modules with high efficiency pro-drivers be used instead of full fledged subwoofers designed to go much lower?...

Re: Flanking Subs vs Helper Woofers
Flanking subs do not get a summed signal - They get the same signal as the main speaker they are flanking, with a low-pass filter applied. They're stereo subs. That's one of the key distinctions between flanking subs and more distant distributed subs in ...
