Ant, what is your recommendation for bass speaker sizes for B string notes, as I typically play slapped and fingered notes on my 5 string bass? 15" or 4x10? I just bought 2 new 4x10 cabs to replace my recently blown cab containing 2-10" and a 12". The lows are definitely not there with this new setup. Thinking about adding a 15" cab to the mix. Any suggestions? Thanks!
