For a 3 way speaker with sealed bass I'm thinking to extend the bass using an additional bass speaker in a wide baffle PMS-like design.
Troels G. has used a similar solution on a few occasions. For example http://www.troelsgravesen.dk/NEXT4.htm
Troels refer to it as "kind of 3.5-way".
The sealed 8" bass in the 3-way will be a magnesium W22Ex001, Deep base will be a L26ROY (likely also sealed).
The plan is to run the 3-way as full range and the L26ROY with active-lowpass filtered to pick up where the W22 role off.
For the filter I am planning to use Pass DIY 6-24 filter.
QUESTION:
What "Q" do you recommend for the 8" for a smooth transition to the lower-bass and and what filter slope would you use for the active XO?
Any feedback and suggestions welcome.
PS: Speakers and x-over kit already purchased so there most be strong arguments to change these.
