I had a thought the other day, as I'd like to add a subwoofer to my home stereo. Mostly for music, but I really enjoy good subwoofer response in a movie. Although my room doesn't have a great spot for a generic sized subwoofer.
I thought i may be able to build a very short enclosure, with somewhere between 4 and 10 micro subwoofers, something like a 2-1/2 inch or 3 inch subwoofer, and laying them all flat, to fit underneath my entertainment center. I think with enough of them I could get a similar response to a standard sealed 10 inch driver. The enclosure could be as deep as the furniture, about 14 or 16 inches deep, and practiacally 50 inches wide.
I think there would be enough volume to make the subwoofer box work, but I wanted to know if somebody thought this may not be a good idea for any reason. It wouldnt have a huge power demand, and I feel like it may blend with the towers well if it spanned the distance between them.
Anyone have any thoughts or concerns on the idea?

If you google there are plenty of 'under soft' subs and of course the incar market.
Efficiency will be low of course, but that comes with the territory. Real questions are
1. how low
2. how loud

The other hurdle I have is that the couch is in the center of the room, with tile floors. So putting power and signal under the couch isn't a great option for me.
Imagine something like this picture I've attached, where the subs all face forwards, side by side, and the entertainment center would be the seat.
If a ported option appeared to work with whatever drivers are chosen, that's also an option. With a port in the center, or possibly one on each end?
I don't think it would need to be extremely loud, but a moderate extension would be really great

Why so small? TB has an intriguing 5 1/4 sub that will go low but you would need at least four of them, or better 8. Slot loaded under the couch. Fun. Wish they had been around 30 years ago when I was doing car audio.
Edit: the 6.5" looks better with lower fs (35) and more excursion. Still small enough to go under a bench seat.

One of those TB mini subs someone at PE did a 'flat sub' project with 4 of them.

Good for ideas.

Cost might be prohibitive. One large woofer is cheaper than a bunch of small woofers with the same displacement and distortion figures.
I would look for an 8" with low fs in a sealed ~10 liter (~ 2,5gallon?) box, and put it in a corner of the room.
I think it's a great idea if you can deal with the limitations. If you use something like the Aura NS3, you'd need 10 - 12 of them to equal the Vd of a 10" driver with 5mm of xmax and it would cost you $200-240 in drivers. With 1/2" material, you could make the enclosure 4" tall and get some decent output. If you could bump the enclosure height up to 5", you could use the Dayton ND105. At 6.25" tall, you could jump up to the TB W5-1138 and produce some substantial bass with several of them. I think this would be a cool project!
