I just recently set up my HT room with the DTs and I still would like to see more bass. I've been thinking about 2 end tables that are really subs. I don't know if it can be done but it would be nice if nothing vibrated off the table subs as well. Any ideas?

sure, you could do that and several folks have.

a dual-opposed design would eliminate resonances.

a bottom firing design might work too if the cabinet was nice and heavy.

it is really up to you to select how you would like the end tables to look and be constructed. if you need help choosing drivers and amplification, you'll get plenty of suggestions.

have you poked around the stickies (index and gallery threads might give you some ideas).

Listen. It's All Good.

I'm worried about stuff vibrating off tables and shelves in other rooms of the house. If you want your bowl of M&M's to stay in place on your subwoofer end table you have conflicting design goals.

You can make it D/O or down firing. Either should minimize movement. Go a bit overboard on bracing for the table top and extra weight, like a slab of granite for the top, will help too. Having a concrete subfloor will help. If it's in a room w/ a suspended floor then the floor and everything sitting on the floor will resonate.

You typically need 200 to 300lbs to stop a sub from shaking; OR you could do dual-opposed which is basically a two woofer box, one on the front and on the back.

The only downside of dual-opposed is that it costs nearly double, and the box volume is slightly less than double.
Using two 12's you could make the box (probably) 13x13x20 and two 18's the box would probably be 20x20x22.

Two Dayton HO-18's and a nu3000DSP is a common solution.

Not at all. Leland Crooks built this combination TableTuba/CD/DVD case, and the stored CDs,DVDs and doors don't even rattle. It doesn't weigh even 100 pounds, as there isn't a piece of wood in it thicker than 1/2 inch.

I like the idea of a granite slab on top of the subs. So I've been researching the dual opposing sub configuration and that looks like a good direction to go but I have another idea, how about dual subs in a box facing each other at an angle? They would be in the center of the box. The angle would be towards the floor with a vent between them at the bottom.

I went with endtables in my setup. They work great and no one even knows there are subs in them.

I orient them so that the grilles face the couch so they are not seen either, but are removable via neo magnets inside the enclosure.
You can't see the wheels in everyday use either, only when using flash photography as they shadows hide everything.

I would recommend it to anyone if you want to be inconspicuous with your setup.
