In the front of the theater I have a few problems I need to address.
I have a pair of Magnepan 3.6s and a CC3 center channel. I have two DIY subs. And I have an amp (Cinepro 3k6SE) sitting on the carpet that drives the two subs. The CC3 sits on a speaker stand I made for the old center channel that is now upstairs in the family room. I would like to clean things up. I have been working on an idea to combine the pieces. I am looking at a combination Subwoofer, Amp stand, and Center channel stand.
I have modeled up some concepts on how to have two 15 in sub drivers, a hole in the back to stick the amp and a place to house the center channel. I show the subs in a back firing, a down firing configuration and an opposing configuration one as well. I am assuming that the opposing configuration would be the better since there would be less vibration, but with something as big as this would end up being, mass may overcome the vibration and not be a problem. And I would prefer from an aesthetic stand point to have the drivers facing down or back. The drivers would be two more AV-15s from John at Acoustic Elegance.
My thought is that I would use a sealed design for the subs to match the two existing subs and have a 3 cubic foot per sub volume. Would likely use plate amps to power them. These would also be run through a Marchand BASSIS for some low end boost and a BFD for equalization.
The Cinepro amp has fans. I hate fan noise. And the fans do come on, especially when I listen to bass heavy music. So am wondering if I can do some acoustic trick inside the hole I am planning which could lower the fan noise. Either line the cavity with foam or attenuate some other way.
As far as the speaker stand part goes, I leave the back open for the Maggie center back wave. I assume this is necessary, although have not contacted Magnepan about it.
This way, I get two more subs, a way to locate and reduce fan noise and a less obnoxious speaker stand.
The finish would be cherry and similar to the finish on the Maggies, the bracing I made for the 3.6s and the DIY subs.
I would like feedback on whether this is a silly idea or constructive criticism on how to make this work.
