My big Eden amp, that I usually daisy-chain to a 1x12 and a 2x10, is being serviced, and I have a rehearsal tonight. I want to use my little WTX-260 with one speaker for the rehearsal. Can I use my WTX-260 (260 Watts 4ohm minimum) with a 2x10 (500W 4ohm)? Or do I stick with the 1x12 (250W 8ohm) - that I've used before? I need the most volume - not picky about tone at this point, just need to keep up. I promise to study resistance compatibility later if somebody can just give me a bottom line right now as a help at the last minute? (I'm not thumbing my nose at the awesome teachers out there, I'm just overwhelmed with selling my house, making a move and having a last-minute gig all at once.) Thank you!!
