I'm looking at doing a very similar project with the 3" TB full ranges for my computer speakers. I haven't figured out what sub to use, but the TB 5.25 looks pretty good.
I assume you've finished these by now. How do they perform? Also, what amp did you use? The apex jr. is a little bigger than I want (I'm want the amp to be seperate from the sub), and the only other thing I've found that looks reasonable is the 30W Velleman kint from PE. Any advice is much appreciated.
Thanks,
Sam
