The T-Amp I'm thinking of is $30 from PartsExpress (300-952). At least for me, I have the drivers already. They were ~$10 at Radio Shack when they carried them. The tweeters I'm getting are Dayton neodymium domes for $5ea. I'll have 2 leftover FE-103's when I'm done. For the sub, PE has Dayton DVC woofers for ~$25, and I already have a LM-3886 amp made up, so I'm out an additional $70 (DVC woofer, T-amp, power supply. I have to make up an active crossover and I'm set. Let me know if you want the two FE-103s.
