I want to put together a couple of cabs to replace my cyclops speakers. That combo just isn't working out for me and my band. I can't get enough clean volume or the sound I want out of that set up. My plan is to go with two cabs. A 15 or an 18 separate with a 2x10 or a 4x10 with a horn. I am considering a eminence kappa 18 for the low end in a box that is 36-3/4 x 25 x 16-1/2. It is 400 watts. I will drive this set up with my Carvin R600 amp. It can be biamped, stereo, or bridged. Can I run the 18 by itself till I can afford to get the other cab?? And how will I balance the other box once I get it? Watts,ohms,frequency,etc? So back to the question,"will the Kappa 18 work well with a combo or by itself"??
