SMT112 top sufficient for dual Cubo 15?

you can get away with 2 amps and a crossover for a good sounding non-bank breaking system.

..may i recomend matrix amps if you havent bought/thought about amps yet. i have a similar set up and use a 800XT for tops and a 6004XT on bass duty. its very light weight and with a set of wheels a nice one man mini touring system

if your getting them for a good deal i dont see why it wouldnt be worth a punt. good output and if your getting two should suit your system quite well. i think your skimping a bit on head room for the subs but as iv never known anyone to own one of these amp im sure if its not up to the job you can allways sell it on for the money you paid and keep one for just the midtops.

Just wondering as you said they don't have much output below 160hz, could they still be used down to 100hz just without much kick, or do they start to sound bad. cheers Ollie
