How does it sound for box size. 6th order bandpass rear chamber of 6 cubic feet @ 36hz and front chamber of 22 cubic feet @ 63hz. Wanting to get things started for a build next year. This is a spl only build.

For a 6th order I was thinking 1 or 2 18's. If needed can go back and get some 15's. Thats why I was wondering and thanks.

    Sounds like you could fit two woofers... back chamber is a LITTLE small for two 18s but sounds perfect for two 15s.

    Would 8 cubic feet be better or 10 cubic feet for 2 18's. Also is the tuning about right on a place to start.

    With 8-9 cubes rear two 18s would work well, IMO.

    Tuning sounds like a good starting point... although, large 6th orders are a great deal of trial and error.
