When I was just young and buying my first bass amp, I was led astray by companies selling a 4x10 matched with a 1x15. After lurking TB, I've decided to replace the 1x15 with either another 4x10 or a 2x10. I have a Carvin BX1200 Head, with a BR410-4 cab and a BR115-8 cab. I'm selling the BR115-8 and would like to replace it with a Carvin BRX series cab. Which speaker would compliment my current setup better, a second 4x10 or a 2x10? Also, does anyone have experience with either Cab? Thanks!
