Your question has to do with the NC115 (Nemesis combo) model, correct? If so, the following might be helpful.
One of my favorite amps of all time is an old Eden Nemesis 2x12 combo (NC212: 225 watts RMS @4ohms, 350 watts peak, 102db SPL, compressor, semiparametric EQ, DI level, effects loop, tuner out, headphone jack, composite cabinet). It's the one with the cooling fins on the back, pre-internal fan. It was an affordable back-friendly tone monster, handling a B-string with ease.
It was reliable, had great tonal character, and was flexible in use due to the excellent DI output to PA. As a standalone, it had juice to spare, even in the realm of a heavy-handed rock drummer. However, once drum mics are used, you'll need PA support.
I have several friends that swear by their 115s and refuse to use 10s and 12s. I am sure that only the 15" version of Nemesis would satisfy them.
Here's the Eden "no secret" recipe: Connect your bass. Set the tone controls flat (six o'clock). Set enhance at zero. Set volume levels. Play music!
However, the most important opinion in all of this is yours. Test it before you buy it. (See the green link below for some ideas.)
If your question is about the N15 cabinet, ignore this post, except for the line above.
