Craig, I know that many companies do a 10" sub with a passive 12", is there any reason that nobody seems to do a 12" with a passive 15"? Or am I just not looking hard enough? Or is it just better to do a single 15? I know that you have the Scamp, the Sasquatch, and the Pinache sub in the works, but just wondering if something like that would ever be a possibility?
