The amp is 800 watts at 4 ohms. Cab is 500 watts at 8 ohms. What cab would you recommend to add to this rig to open up the amp/sound? Another 410HE (a lot of would space be taken up in the house, but not out of the question)? A 115? 212? 210? Any brands/models/speaker configurations considered. Just has to be 8 ohms, similar wattage, and either a similar sound or a sound that would mesh well.
