I am in somewhat a similar boat that I am beginning to put another system together
not too different than yours. Except I like simpler projects...yours is a beautiful but
could be a real gorilla in tweaking...but no doubt it might be worth it.
This is what I'm finding out and your right Steve I think it's worth it.

I'm thinking 511E but with GPA288H drivers...the high end is better methinks
so I do not need the ev tweeters...though gm may add that the ev tweeters bandwidth

may be more appropriate.
I have a couple different pairs of 288's ,I want to use these because the diaghrams are Brand New
Still I truly believe the fewer number of transducers...the better.
I'm thinking of the alnico gpa 416 speakers...I want brand new...that's just me.
1 pair of 416's are used but in great condition and the other pair I have are NOS still in the Altec Boxes.If I need to recone them (Used Ones) I will.
But if I had 4-416's...then zilch's comments are spot on not just because that is exactly
what I would do. But it makes me think I could design a 3 way system with the behringer
and maybe have some passive xo across one of the 416Bs to keep the other one focused to
the midrange horn....now you got me thinking
But I truly believe that 1 woofer cannot keep up with a 288 without having to shelve it completely it just overpowers and drowns out 1 LF transducer.In almost every Altec system that a large format driver is used 2 woofers are usually the norm.Let me know if you come up with anything !!

I'll send GM a email see if he can help Thank You Steve ! :2thumbsup:
