The Dahlquist DQ-LP1 has a passive, 6db/oct HI-pass section that is transparent to your system(use a good polystyrene or polypropylene cap there), and an active 18db/oct LO-pass circuit that enables you to dial in your freq(up to 400Hz), level and low freq EQ(boost the bottom a bit). I used one from 1981(always bi-amping planars), 'til 2004, when I went with my TacT RCS 2.2X. They generally sell for around $300(what they sold for in '80) ie: (http://cgi.ebay.com/DAHLQUIST-DQ-LP1-Variable-Low-Pass-Filter-USA-Made_W0QQitemZ260440261155QQcmdZViewItemQQptZVintage_Electronics_R2?hash=item3ca3730223&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A1%7C72%3A1234%7C293%3A1%7C294%3A50) The crossover's designer(Carl Marchisotto) also designed the Alon Exotica Grand Reference system, which still uses the DQ-LP1 as it's HI/LO filter. Allegro Sound may still have one also: ( http://www.allegrosound.com/Dahlquist_DQ-LP1.html )
Behringer Crossover for Maggies vs Bryston
There is a 3-way stereo crossover from Behringer
http://www.behringer.com/EN/Products/CX3400.aspx
To get 3-way stereo crossover from Bryston B10sub is 6.4k or so (you need 2). The Behringer is $130.

Has anyone tried this? Does it really sound that bad? 6.4k is a lot of cash that could go into 4 mono amps... I know Magnepan uses Bryston at the factory and it perfectly meshes with the Magnepans, but still. $130?
I know I don't need the 2nd, but it would be so nice to run sub in full range mode and use the active out, also maybe lift the Maggie low end to 60 HZ or something, releive the panel of a bit of the super low end.
I have 3.6s.
One thing I was thinking is use it as a stepping stone. Get it, focus on the amps for now, wait a year or two, then put the Bryston in.
I'm familiar with the Marchand route, and maybe that is a better stepping stone, but just curious if anyone is familiar with the Berhringer.
