I have a 4 ohm goliath II Junior, and was wondering if there is a reasonably simple way to convert this to 8 ohms? Also wondering if these drivers would be the same (speaker only) impedance of the 4 ohm goliath senior (6x10) I own? Looking for a way to run both cabs off of a single amp, with a 2.66-4 ohm draw. best way IMO to achieve this would be to have the jr. at 8 ohm. Help?????
