Thanks, nice to know my memory's not completely shot!

Yeah, I didn't have a clue what SAF/WAF/SO/whatever alluded to when I first got on the early DIY speaker BBs since it was never an issue with the various wives/S.O.s I was exposed to during my building 'career' no matter how big the cabs got (up to 30 ft^3 and one 300 ft^3 false wall IB). I guess it was due to asking them to be proactive over how they were 'voiced' since females typically hear better than males (especially in the extreme HF), and due to their reproductive system they are more sensitive to the lower frequencies to boot.

I guess there's a design in that thread, but in a quick scan I missed it.

Sure can.

Yeah, Altec has already measured the phase alignment offset in both planes, so why re-invent the wheel, so to speak?
