I'm coming up with ideas for my build and more than likely I'm putting more into this than I should. I probably ought to just build a basic ported box with port and sub firing backwards but I wanted some opinions on one design. This design would have both firing forward into the ski-hole with the ski-hole opening measuring 6x10" which could be made bigger if need be. Of course, I would seal off the trunk in some fashion, but with that in mind, I have 3 questions.
1) would this go from a regular ported enclosure to a 6th order, with the enclosure sealed off to the angled back seat?
2) The area in front of the sub, would some of it actually serve as part of the port, thus making the port longer and tuning lower?
3) Any phase/cancellation issues that you see with this particular design?
