Questions for the OB/dipole experts.....

[mayhem13]

So I would like to use the Eminence Deltalite 12 OB from 1.2khz on down to 250hz as a midrange. Below 250hz will be a monopole woofer with an active low pass. The baffle width of the monopole will be 19" so I'd like to be consistent although the the enclosure will modular. I'm figuring I'll have to use a U-frame so was wondering on suggestions for the dimensions of the sides to use the dipole peak to my advantage with as little notching as possible.

Up top will be a Beyma TPL150 or Aurum aero-striction.

Thanks in advance and FYI, mid and high parts of the system will be passively filtered.

250hz CO point is too high if your monopole woofer will be close to floor.
and for lower CO you need either DSP EQ or a very wide baffle.
