I've read and read. Perhaps under the explaination of options, this could be added to the flatwinds description if it holds out to be true:

Does Flatwind add power handling and excursion at the expense of sound quality?

Flatwind: The flatwire coil option simply helps the power handling of the sub. The coil has more surface area to dissipate heat and will take more power then the regular round wire coil that comes in the

Yes, it sacrifices some SQ, but adds power handling. What kind of music do you listen to?

Incorrect. It simply makes the woofer more prone to peaking. IE in a ported application, you would need a slightly lower tune to remove the peakiness of the flatwind option sub. The flatwind sub will however (due to being more peaky) show more gains due to a "higher" tuned set-up.

I listen to Rap/Hip Hop

Some say it lowers SQ so that's why I'm confused. So what you are basically saying is instead of porting and tuning it to about 32Hz, that with the Flatwind option it should be tuned lower?

I just purchased 2 BL 12's with the Flatwind, Pchamfer and Daily option. Still working on the ports for the box. Dimensions are done though, just haven't figured out the tuning yet.
