I just got home from a gig using my new Carvin BRX10.2 cabinet. I ran it through a Carvin BX500 head. I was absolutely amazed at the low end the cab produced in the club where we were playing. It was shaking the room. The guitarist and drummer also were pleasantly surprised. If the 2x10 cab produces that much low end I wonder what my BRX10.4 cab through my Carvin B2000 will sound like. My old cabs never got this amazing thump.
