Bob, hope you get a chance to read this. Otherwise, I may call you again in a day or two, unless things are obviously out of whack.
This is partially my fault, I suppose, since I took so long before finding out this problem:
So I finally unpacked all the drivers to install them. Previously, I had just done a head count to make sure that all drivers were present. Well it turns out that part of the surround on the last woofer I needed to install is warped. Looks like it was sitting on something for a long long time and is permanently deformed. I installed the woofer anyway, and I'll give the speakers a shot tomorrow. I finished them late, tonight, and there's no time for me to set them up.
What should I do about this woofer? I'll post pictures, if they turn out clear enough.
Well, I did a little testing despite the hour. I'll give you a ring tomorrow.
