BL 15 Box help

[dtcharneski 0]

Ok i'm going to be building a box for a Bl 15 4.0^3ft @32hz. And I was wondering where would be the best place to mount the speaker in the box. Its going to be a slot ported box. Should i have it closer to the edge of the port or the other end of the enclosure? What about the top? I hope this isnt to confusing. I just want to know if there is an optimal position for the sub on the box.
