I have a LDS 1x12" with a tweeter and small midrange driver. I ordered it as an 8 ohm cab, assuming I'd be getting another cab to stack it on. It's been a couple years, and I think I'm more likely to use it by itself or run my head at 2 ohms. I'm not sure what speakers are in it, but would I not be able to buy the same type of speaker or combination of speakers that would make it a 4 ohm load? Thanks for the help!
