I too have his 399 drivers. I use them on 500hz round wooden tractix Edgarhorns.

I prefer JBL 15" drivers for the bottom though as they take up less real estate.

NIce looking system!

I crossover at 2nd order lo-pass/3rd order hi-pass @ 800hz.

What efficiency do you end up with your system???

I am guessing around 100db/watt???

Good for tube amps I'm sure!

Thanks for sharing your system with us.

Nice job on your speakers.
I wonder if adding some fiberglass batting to the inside of the cabinet might be good idea?
