Hi.Interesting idea.I have just removed the staplers under the sofa and see that there is about 20cm of empty thickness and about 256 liters of volume under the sofa and also there is extra volume of about same volume after the sponge starts(the thickness of sponge is around 20cm too and finished with faux leather on the top)So there is 512 liters of empty volume in total. I think i will also start to vibrate when i build a downfiring sub under sofa.So i need to seal it right?Has anyone tried without sealing? What happens? Is there any good example around with leather shaking?

You're probably not scoring any points, taking apart the family couch.

I always though the idea of the "coffee table" sub to be a good idea.

You get good bass close to the listener because its usually placed beside a couch. It's a good place to put things (flowers, books, coffee, beer, toys, etc). It also fits into the decor if you design it right and fire the woofer downward to hide the workings.

Yes, make it push-push and it won't shake things onto the floor either

Dunno, Dave (plant 10) is an advocate and chrisb though they will insist on using the term mid-tweeter. FAST is still ubiquitous on google search. Adding WAW to wikipedia would probably help in that regard

That's true, I think a lot of people use Wiki. Myself included.
