Hey everyone,

This might be properly addressed to Danny but anyone who wants to chip in go for it.

I'm persuaded that Danny's right about open baffle bass and that the Rythm amp he offers is superior.

That said, open baffle speakers require a large enough room that they can be moved out from the front and side walls. Most people do not have large rooms that they can use that way, especially when the WAF factor is considered. I know Danny offers a sealed sub too but man that cabinet is big.

Decware's Wicked One Subwoofer Cabinet design might be the way to go. Steve sells the plans for $20. bucks.
"The Decware Wicked One is a compound horn loaded dual band pass design where each half of the box shares the same horn flare." The design can work with 12" drivers.
Correct me if I'm wrong but I see no reason why the Rythm amp and twin sub drivers wouldn't work with that design. What do you think guys?

Each sealed sub only needs 1.5 to 1.8 cubic feet of air space. That's pretty small.

In a configuration like that you are loading the driver on both sides. So the sealed air space side would have to double. Plus space for the horn and you'll be in the 10 to 12 cubic feet of air space range for both woofers. Now that's big.

The box would have to be designed based on the T/S parameters of the woofer, but that doesn't mean that it would work. It will change the way the woofer is loaded at different frequencies and the servo control system would have to be changed to match it.

It would also take it from a flat or linear response to one with increased output based on the tuning of the horn. So it would have a humped up response.
 
Then you have to deal with cabinet wall resonances. Walls have to be super well braced or super thick to avoid those issues. If not well braced then at least 3" thick. Now you're talking about a 400 plus pound cabinet.

None of that really sounds like a good idea.
