I'm trying to find a 4 ohm lightweight cabinet to use with my recently purchased EA Micro amp. When I bought the amp, I didn't think about the idea that a 4 ohm cab may be better suited for it...and I'm trying to replace my 42 lb 12 inch Aguilar with a lightweight cab. Any suggestions on a lighter cab thats 4 ohms? Am I overthinking this whole thing? It's for an upright not electric.
