Hello, I have been building my rig for a while now and am looking for advice. I am running a two stack set up: 1. More of my high tones -Hillbish Beta-pre>Crest Prolite 3.0> a custom Nomad 6x12 with Ted Weber Black shucks (1200 watt @ 4 ohm) and 2. More clean tones - Mesa Subway DI > Crest Prolite 2nd channel > an Ampeg SVT 212 (600 watt @4 ohm) and Custom 1x15 with an Eminence Kappa Pro-15lfc (600 watt @ 4 ohm). The issue I am having is that I dont really think the Eminence 15 sounds good (its a PA speaker so not that surprising) and I would ideally like to get to a 4 ohm impedance. I eventually want to replace the Mesa DI with a real amp for my lows/cleans (like an Ampeg SVT or V4b or something, I'm open to input on that as well), but am not sure what is best i.e. another Ampeg 212 (although I would like to run a 4 ohm stack) or just replace the speakers in the Ampeg and 1x15 with better suited speakers, or a couple Orange 1x15s. Obviously, I dont need two 1200 watt stacks (or one probably) so I am looking for thoughts about a solid stack for great lows at high volume that is also 2 cabs for the times when I cant bring all my cabs and stairs are an issue (not looking for an 8x10). I play in a few black metal/grind/drone/harsh noise/meditation/and experimental bands as a consideration.
