$400 for a 1200w RMS sub is not a good price at all.I think you're getting the idea
Pretty much nailed it. IMO you are running that L7 at its limits and risk hurting it. The 9500 is a **** good woofer, the only thing wrong with it IMO is the price tag, but at 400$ it isn't terrible. That should handle 1200W continuous power (sine wave round the clock).
Sorry you ran into such douche-baggery here.
