I have a quick question. I have an Avatar B212 that I picked up locally for $50. In fantastic shape. It is an 8 ohm cab with two 4 ohm Avatar Deltalite 2 wired in Series to make it 8 ohm. I sent pics to Dave to verify. I want to convert it to a 4 ohm cab so I can use it with my SVT head. Considering I paid nothing for the cab, I am open to buying new drivers for it and making it 4 ohms. I know that Dave doesn't use precise measurements when designing cabs, but would you think that 2 Deltalite 8 ohm speakers would work better than the old GB Faital PR300s that Dave sells in there? What about Kappalites?
