I have an 8 ohm Hartke 410xl. I am thinking of getting a 4 ohm 4x10 cabinet to better utilise my power amp's power. My question is if anyone is aware if a Hartke 410xl can be rewired to 4ohms? I know this depends on the resistance of the speakers and how they are wired. I have made speaker cabinets in the past, so I am not completely ignorant to ohms and speaker wiring! Of course I can just take the speakers out of the cab and determine this, but if someone out there already knows, that could save me from wasting practice time! Thanks in advance for any help!
