I said that I scored a Yorkville a couple weeks ago. That is good! I've been daydreaming at work again and I'm curious about adding a set of 2x10 cabinets (assume 4 ohms) to compliment the 1x15 (4 ohms). It says that the output is 150W @ 4 ohms and 184W @ 2 ohms. Is it worth adding the second cabinet to enhance either the volume or tone? Will the extra 34W be enough to drive the additional cab?
