Bring some cardboard and a knife to audition them, to find the ones that get the best bass on OB in the $5-$15 range. You want to listen to the ones with the smaller magnets which indicates higher Qts.

This sounds very good. Are you sure that I can get away with a dipole design? I only have sixteen inches from the wall to the screen. I could build the bafle right up to the screen. Would the sixteen inches behind it work?

I can fit quite a few drivers on a baffle of 3ft by 9ft. They will all be fed a mono 300 watt + subwoofer amp (a bridged Kenwood amp). Total impedance should be 8 ohms after proper wiring. If this will work can anyone suggest good drivers to use?
(links too if you have one)

Thanks

... and it costs 85 bucks. Nominal F3 would be about 30Hz. That's some way deep bass. Someone who knows something about this stuff would have to say whether that would be too boomy in the particular room the setup is going into.

Wow! Way cool find. Thanks!

My garage is right behind my home theater and I could easily mount four of these to the wall with some work. Do you guys think that four of these mounted directly to my wall might be a better approach than going with dipole design?

With that much space you might as well go for a 20Hz horn...

That's absolutely right. A good bass horn could be the cheapest option driver wise and get huge output if well executed.

How about a pair of labhorns built into the unit ?
I listened to one at Yorkville Sound and it made my pantlegs flap.
Build the Horns!

I just have to figure out how to hide a pair of them where my wife won't find them. My workshop is under the livingroom....

I'd say 4 of the regular daytons, their $27 each when you buy 4. Their pretty good quality in my opinion, their pretty heavy and solid for the price. Plus with four you'd be looking at like 96db sensitivity and 8 ohms, add a modest plate amp and your set for $250 excluding wood.
