I have a SWR SM500 and I like the tone I get from the amp, when going DI - but not when running through my cabinet. When I need to go to moderate volumes I lose some punch from the cabinet. Right now I am running into a mesa boogie Road Ready cabinet (4x10) which is wired for stereo (2 x8 Ohms). If i remember correctly that gives me 150 watts per side from this amp, and I am wondering if I rewire to a single 4 ohm if I can expect to get some added punch and better dynamics at more volume. If it matters, this is an older RR model (non-ported) with Eden drivers. Thanks in advance for any educated opinions.
