I recently purchased a 8" speaker for my champ clone and it arrived dented and warped so i'm back to looking for a suitable speaker. I have found a 2ohm alnico vintage speaker local and wondering if it would be suitable to use on the 4ohm output? The speaker currently has a line transformer mounted on it rated at something like 500ohms. I would want to remove that and run the speaker on its 2 ohm rating. Would there be any negatives to doing this?
