I have an GK RB700-II which is 320 watts at 8 ohms. I use a GK BLX-II 410 rated for 400 watts. At practice I have my volume maxed on my bass and at 7.5ish on my head. The single guitarist only has his 50 watt fender tube amp at 2-3. The drummer has a kit with 20+ pieces that is running (not terribly loudly) through the pa, along with the singer's vocals. I feel like I should not have to have my amp almost maxed at 320 watts to keep up at practice. Is it the fact the cabinet is nonported? I heard ported cabs can be louder than nonported. Are we playing too loudly(my ears never ring and I never feel uncomfortable with the volume)? Eventually I'm going to be upgrading to 2 Neo 212's. If I am using one of those at practice will I have the same problem? Am I just an idiot and this is normal? P.S. I'm not as dumb as I sound. I've been playing for a reasonably long amount of time, but this is the first time I've ever played in a band so I have nothing to compare it to.
