So I just got a new mini home theater system. The 6.5" "sub" it came with does alright (kinda surprised me so far). It's passive so I just would have to build a new enclosure with new sub(s).

Any ideas? The amp gives off ~100W at 8ohm so like (2) 6.5" or (1) 8" or something would be nice tuned low. Let me know. Thanks.

Yeah, I've thought about TB but I've never dealt with any of their drivers.

Posted a response to this yesterday, but don't see it now???

I'd ditch what you have and start from scratch. Look at partsexpress for a plate amp. Plenty of budget subs out there that would work and I'd build bigger than an 8". Never know when you'll be moving it into a bigger room, so I'd do a 12" or 15" and be done with it.

well the thing is the little mini theater system my parents got me for my bday doesn't have a preout for the sub. Sure, I could run the speaker level route but I'd prefer the preout. So I just want to run something off the ~100W 8ohm amp.

Most plate amps have high level inputs like the one here: http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=300-804

I just don't see 100watts doing very much, but I could be wrong. I say buy a cheap 8" sub and build a box and try it out.

There's a sale at Partsexpress for the TB's.

With that power you would be best off going with a transmission line, you wont even need the full 100 to get it going well...

I recently build a transmission line for a single shielded dayton 8, the enclosure is huge, but it only needs around 25 rms to reach full potential, with 104 db response before room gain from 23hz-50....with room gain likely over 110 decibels. TLs for the win...too bad its not a perfect science...
