HI. I just open AL1000 box with bi-amp banana plugs and crossover. I notice that on crossover pcb marked as W+ and W-, wires are connected + to +, - to -, to woofer, but looking at pcb trace, the negative wire from input, from amplifier, is going direct to W+, mean its reversed polarity. Is that normal to be reversed polarity on woofer or its factory mistake?
The original woofer definitely sounds more dry. The kick drum has more body and weight to it via the DXW15 woofer from Dx9. That woofer is vented also and can stand a beating. Do you have any thought as to why this is? Is the cone way to light or thin on the original woofer compared to DXW15?
Well, at least to my ears, I like the original woofer over the orange foam one. I feel the bass is a little more clear than the other one.

Big difference. Thanks now I know. I believe if one goes bad both need to be replaced with new woofers from cerwin.
I need to know the T/S parameters in order to make a fair comparison.
