Ok, I have a few questions. I currently have a 4 ohm Avatar B212 w/ Custom Crossover. Now, I run that with my Mesa Boogie MPulse 600. I would like to put a 210 on top of that 212 sometime, but the problem is that my mpulse only goes down to 4 ohms. So after installing the new crossover in the avatar, I realized that it doesnt seem too difficult to build a cabinet. Now, would I be able to build a 16 ohm cabinet for bass, so when I play the 4 ohm and the 16 ohm cabinet, it will total 4 ohm? Or will it total some weird number and wouldnt be worth my time.
