well good for you doing what works best for you !
i recently scored 2 perfect rare Allison Aboustics dual 8" push =pull sealed subwoofers ! and they should pair perfectly w/ the top of line AL130 speakers which are the L & R of the 2 channel and the L & R of the all allison 11.2 HT system!
i am using the dimensions of them to scale up to a similar dual 12" servo sub push pull DIY model !
but i suspect the pair of dual 12" open baffle wireless servo subs fr the GR research kit will blow them away!
w/ DSP tho you really can’t have too many subs ! and a combination of open baffle ported and non ported should be ideal ! sure do not fancy ported tho !
I bought 4 subwoofers and I'm absolutely not doing a DBA! Hah!
I just received shipments of 4 subwoofer drivers and they will not be going into a distributed bass array.
I'm replacing my left and right speaker stands with powering subwoofers with 2 subwoofer drivers each. I call them powering because they will be powering the 2-way monitors that will sit on top. Here's a beauty shot of the insides.
The amp has all the DSP power I could need to produce perfect speaker measurements. I wonder if JA at Stereophile would wax poetically if I priced them high enough??
