Glad you got the mains done! I'm sorry you're having trouble with the tweeter circuit though. Do check your connections - The treble SPL should be equal to the bass SPL. Without R1/R2 attenuation/compensation, the tweeter would be 10dB higher than the midwoofer, so something is amiss. Could be that you've effectively shorted R1 in some way.

The sub kits have port material included, so wait until they arrive and cut the port hole to match the duct material. The hole diameter shown in the plans is accurate, but having the duct in your hand might help you get it exactly right.
