Nice builds. Make sure you polly-fill'd them about 3lbs each.
I put in about 1.5 lbs in each one...
Need help trying to pin down some amp hum...
I have tried all the usual stuff disconnecting the TV/satelite dish cable /power...
The amp hum is coming through the other speakers, not the sub...at least as far as i can tell...
The hum only occurs when i connect the Crown XLS1500 to the receiver, using the SUB1 and SUB2 out plugs...
I plug them in the channel 1 and channel 2 inputs on the crown amp...
it hums when either one of them is connected...
The hum disappears when these are not connected...
