I'd like some recommendations to some 4 ohm rated 4x10' cabs currently on the market...if any exist. I figured I'd try my hand at hunting down a cab like this rather than buying a 1x15' cab rated at 8 ohms to stack under my current 8 ohm rated 4x10'. I really can't afford lugging around that much heavy gear let alone fit it in my room. I'm currently dishing out 180 watts of power through 8 ohms on my Ashdown MAG300 and would like to get full power out of the amp. I've tried a quick search on Google but I haven't found any cabs that fit my description. Thanks in advance, TBers.
