UPDATE: So, I bought the cab and played around with it and an SWR Workingman 300 and my "rescued" Yamaha BB424X. When I start to crank (Gain @ 3 o'clock, volume past 1 o'clock, equalizer nearly flat with slight boost at both low and high ends, and not that loud in the room), the low E, G and even A were flapping the 10" drivers pretty badly. Am I going to hear a significant difference at higher volumes if I invest in the CA-10s, or should I just keep the cab for lower volume home studio practice as-is (with the Eminence Delta-10As)?
