Hello all, I hope everyone had a great and safe summer, Im kind of looking forward to the crappy weather because it makes me practice more. well anyhow.... It seems Ive blown the H/F horn in my Carvin BRX 210, Its a 4ohm cab rated at 600watts, There are a lot of discussions here concerning drivers but none that answer the questions that I have. Do I need 4ohm driver ? Most available are 8 ohms. What should the wattage rating be ? Do they all just screw on to the horn ?(common threads and diameter) Are there any specs of the crossover that I need to take into account ? Hey Im sorry if this stuff has been covered I just couldnt find it, Thanks !
