Thanks for the replies, all. Im not trying to mke the cabs sound better, just trying to compensate for a problem incurred through excessive lows fom the FOH. I'll try the Nerf bass, thanks Jasper.
i still think that all comes down to pa. I've had excessive lows in FOH and had the soundman ask me to turn my amp down until i looked at him and pointed to the plug that was out of the wall! no amp dude - your bad! gets their attention really quick.
I have to deal... but it does depend somewhat on the soundguy- how intense it all is. Just gotta be prepared for the worst! But I think it's not so bad out front. I see everybody dancing anyway!
