Their unfinished boxes

The crossover...

The Current crossover is a cheap 2.0 coil with a 3.3 shunt on the woofer. The tweeter has it's original filter a 4.7 cap and an unknown coil.

This puts my investment at:
Woofers: $26.00
Tweeters: $15.00
Crossover: $6.00
Ports: $2.00

Not bad for 49 bucks...
