My brother mentioned to me that there are 15's on stands ( that he's been told ) that sound very close to having subs such as the E.V. ZXA5's. I've been reading alot about the Yamaha DXR15/DSR15 as well. Right now we have an eight channel Yamaha powered head and a couple of Yamaha 12 " main cabs and two monitors. Vocals only. The problem is that the kick drum can get buried. We're a six piece funk band that plays in bars of about a hundred or so. Very small towns. My brother will let me use his Presonus mixer and I'm thinking that converting what we have into a monitor system (so that all of our singers have their own monitor) and a couple of the above would be a good way to go. Is this the smart move ? The E.V.'s are about $1,400 each and the Yamaha's are $700/$1000 ea.
