Hi again,

The JBL GT4-15 15" 1000w Subwoofer seems to be quite cheap for the size, I was wondering if this has been used for an AV subwoofer, or if anyone has the TS parameters?

Hmm,

I have to say I am considering this driver, as it seems I "may" (depending on stock) be able to get a couple of these for the price of a single Eminence Sigma Pro 18"

Could two be used in the same cab with reasonable results? Or even four?

Or would I be better sticking to stereo subs with single or twin drivers?

Could this work well in a sealed cab?, and would using a sealed cab negate the requirement for any rumble filters or such?

I am also considering the Behringer EP-4000 for amplification, as the results with a Fusion 12" carpeted box car sub with an amp connected to the sub out of the AV amp were favorable.

Can you post the TS Parameters for this JBL 15"? If I can get WinISD to work (teething issues with Beta OS) the TS parameters might come in usefull.
