Thanks Sirquack
Thats what I fiqured.
As far as the phase goes, I found it hard to believe as well. I double checked with the battery test (I look for the first initial transient movement of the cone). In both cases positive terminal of the battery to positive terminal at the back of the amp (with phase at zero) yielded backwards transient of the cone. Vice-versa when reversed. I checked with 25, 31, 40, 50, 63, and 80 Hz tones. No question, bass is twice as loud and tight.
I think the drivers must be wired out of phase.
Boy, I do like these subs though.....I even find myself listening to hip-hop all of the sudden.
