Okay, this is something that has been bothering me since I discovered that bass cabs are designed differently than PA cabs, or at least since I realized they are not flat sounding and full range. Why are they not full range, un-colored, and flat? It seems to me that if you are using your bass cab in conjunction with a PA, that you are not getting the same sound out of each. I would prefer if my rig on stage sounded as much like what is going thru the PA, wouldn't we all? This really bugged me when, last night at band practice, I didn't bring my amp, I just used my Sansamp BDDI through the PA, which was bi-amped and had an 18" sub hooked up. My sound was AWESOME!!! Way better than through my rig. So now I want my rig, whatever that may be in the future, to sound like this. Specifically, I noticed a lot more prescence and punch, I guess because of the increase hi-midrange and treble I was getting. Man, it was awesome. Do I need to look into Acme cabs? Your answers, comments.....?
