I just got this new a few weeks ago and immediately stuffed the inside with mattress topper to improve the tone and installed a 4ohm faital 15pr400 driver. Unfortunately, I had to slightly enlarge the speaker opening to fit the faital driver. This was supposed to be used for my acoustic gigs but, I found it was easier just to use the small pa so, Im going to sell this off. It was something like $500 through musicians friend but Im going to sell it for $300 shipped in the 48 states simply because some people would be worried about the slightly enlarged speaker opening. The mod didn't effect anything and at this price, should be a good deal for anyone. It comes with the stock 15" driver. I'll get some pics of the mod and the stuffing soon.
