Let's say I have only one 8 ohm speaker cabinet, but I want to lower the impedance of my rig to four to increase the wattage that the amp puts out. What's the best way to lower the overall impedance without buying another cabinet? Does anyone know of an affordable product (load resistor, dummy load, speaker emulator, etc.) that's ideal for simulating an 8 or 4 ohm resistance load? Mainly, I'm asking this because I'm thinking of buying an acoustic image Clarus head, but I'd like to run it at two ohms to get the full 300 watt power output from it. Unfortunately, most small cabs are 8 ohms and I can't afford four of them right now.
