Thanks Tranny.
In my final enclosure, I intend to bring the 416z up high and close to the horn. I turned the cabinet over to get the voice frequencies up off the floor; the horn is around the same distance from the 416z as originally.
I'll try them not toed in; something I hadn't considered.
The screens on the drivers were so full of crud I cut them away.
I can try a shallower xover, like 12db, however I am committed to bi amplifiying. Actually tri, I haven't brought the subwoofers into play yet.
I have tried 25hz tuning of the 8 cubic ft cabinets and it sounded as if the lower mids were pushed back 30 feet. Tapping on the cones yielded a ringing thud. So I added 4 pieces of 16"x 24"x 3 1/2" fiberglass to the fiberglass that was in the original enclosure. Tubby bass.
Then I substituted different venting at a Vb of 40 hZ. Together with the added fiberglass, it really sounds solid. Maybe I'll take one piece of 'glass out and try that as well.
Funny thing: with the 40hz tuning, when I tap one woofer it has that dead sound I think it should. The other has some thud.
What I am really looking forward to is a well braced baltic birch cabinet for the 416z and a sand-filled box for the horn.
I hope this happens in the next month of two.
Thanks for your insights.
