Re: Flanking Subs vs Helper Woofers
You can use flanking subs on every main speaker you have, for every channel. But I think the most important channels are the L/R mains, because they are so important to the presentation. Still, you could run flanking subs on every channel. That woul...

Re: Flanking Subs vs Helper Woofers
I can see how this works with stereo. But it's not as clear to me when it comes to multi channel audio where the LF content from at least 3 more discrete channels and LFE are all summed in the subwoofer signal.

Re: Flanking Subs vs Helper Woofers
Absolutely. That's precisely what you want to do. The more bass sound sources there are, the better. So the two flanking subs become two of the four distributed multisubs at low frequencies.
The summed LF output is only being run to the distributed...

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?
Thank you very much.

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: speaker location and type
Speaker placement depends largely on the type of speaker you choose. Some need to be in free space, not near walls. Others work better when placed close to walls. Some are designed to be placed in corners. Some should be pointed at the listening area...

Re: skywave's 3Pi subwoofer build
Flanking subs are stereo pairs, one for each main. So you really want them to be matched, e.g. a pair of three π subs or a pair of Genelecs or a pair of Daytons. If you can't have a matched pair, I would be worried that the balance would be off.

Re: 4PI Cabinet plans / question
Is there any reason why the same logic cannot be extended to tapped horn subs? In other words, can THs be mixed with sealed and bass-reflex subs in multisub setups?
