It's always a pleasure to hear numbers that are based on experience. I'm curious about that 220 figure for the side port though. What vintage housings are you talking about, and which form of porting? Surely that's not a bridgeport on REW or Cosmo housings. What would you expect to see with a mild/street port on a set of REW housings?
