Well, I decided to jump on a Power Sound Audio XV15. I was in the process of finding the e-mail for them to ask about what difference the base makes when they e-mailed thanking me for the order. (Yes I ordered.. then asked.)
After e-mailing them back with my question and getting a response in no time at all I am extremely happy so far! They even suggested to save a few bucks the XS15 may even work out okay, but I think I will stick with the ported XV15.
That kind of thing makes you proud to support a company in your own state, it is sad that this is the exception and not the norm these days but if the sub is half as good as the customer service this far I can't wait!
While I can't speak to the Sub yet, so far the people are great! (Big thanks to Tom!)
