~50 cu. ft. enclosure with two Mal 21s in a dual opposed fashion, but manifold-like. Ported with a 12Hz tune.
I am considering doing this.
1. I need to use these two Mals.
2. It seems to model pretty well in WINISD.
3. I have talked the wife into this as part of our living room entertainment center.
4. I need to build a frame on this wall anyways, to hold the Black Diamond screen material I "acquired", so this will be "part" of it.
This sketchup was just a quick model to show the manifold placement i was thinking about.
Manifold width. Curved corner to back of manifold? Angled wall in manifold? In the sketchup the manifold opening is 8x30.
I modeled it with two 2x20 slots about 19" deep. It show almost 37 m/s with 3200 watts at 11-12HZ
I'll do a model of the room and the entire box/entertainment center idea later today or tomorrow.
