Oh ok. I'll research the super scooper more and when I have enough information I'll present the proposal to the rink owner and see what he wants to do.
That said I did adjust the crossover this past weekend and the current subs seemed to blend in better, but still aren't good enough as on some songs that have a lower bass note that varies down in frequency I can hear the bass start to drop off and start to feel the vibration of the subs themselves.
