This is going to be a long post so hang on. I use an SVT-4 Pro as my gigging amp. When I need big sound I use my Ampeg 8x10....heavy! So for smaller gigs I thought a 4x10 might do the job. I picked up a used BSE4x10HLF cheap and it sounded okay until you run some power to it. I was getting speaker farts at low notes on the E string especially a fretted A or B. So I bought four new Eminence Legend 4ohm 200W RMS speakers and installed them. They are supposed to work in ported or sealed cabs. It works a little better but I still get the flapping or farting noise. I then blocked the ports on the cab and that seemed to help some but it still occurs....so I am wondering if a 4x10 is the right way to go? I am running maybe 4-5-6 hundred watts at playing volume. I have played with the settings, used active/passive basses and it seems to help going passive. I have no such issues using the 8x10 at very loud volumes, but it is a hassle for a small venue and it scares some club owners! I was looking at Hartke 4x10 1,000 watt rms cab, along with other brands. I was trying to keep the weight down. I really like Ampeg stuff but the only cab they have that is rated above 800w is the Neo cab for big $$. I wonder if it would handle the juice? Anyone have experience or advice on a solution?
