"... Not using the external Magnepan crossover boxes. ..."@Roger Gustavsson,
He is not using the bass panels.
He is using the 3.6's OEM overlapping asymmetric XO points and slopes (LP250/18dB HP200/6dB) to actively biamp the stereo triple subs. He used the servo sub's plate amps phase adjustment to fine tune the phase matching.
I am doing a similar arrangement with my 20.1's but with different XO point slopes.
This has been done before and the following is the first time I am aware of. This image is from an old defunct/archived audio forum where a guy's bass panels went south. Considering the shipping costs for 20.X bass panel repairs, he made stereo OB/Dipole line arrays to replace the bass panels and gained extra extension in the process. If memory serves, he used 10" drivers here.
