Dual 416-8b MLTL design

[Mercury3]

Thanks for the reply GM - I have read as many of your other postings as I could find so I was hoping you would chime in.

I'm not familiar with those AE woofers but I'll have a look. Nice thing about the Altecs is they sound good into the lower midrange which is tough for large woofers. If I go with 511-b I probably be close to 700 hz.

Yeah I'm old school and was always comfortable tuning the ports the old fashion way with a signal generator / resistor while measuring the two impedance peaks. Some say it's antiquated but crap I've built some damn good subs in the past that way.

Having said that some of my best subs were of aperiodic designs. I've got a pair of those 6 cubic feet cabinets in each corner now. With room gain those are only a couple of db down at 20hz. There great but I'd have to ditch those to make room for the transmission lines. If I kept those I wouldn't be able to go with wide cabinets. I've thought about it though but then I'd scale down the 416 boxes.

I need to think on this thoroughly as at 64 these will be my last build.
