    I have a bit of a dilemma. I have the parts to build another MKII 10" sub for HT use. I'm debating on going with a PR or going with a port. The problem is that the port length is too long. The ported enclosure I want to make is a 1.41Cu Ft box with a 19.3"x3" vent, tuned to 27hz.

    A quick call to Parts Express asking about PR's, and they recommended a 12" Dayton PR Part # 295-192 with no added mass. But they couldn't tell me what it was tuned to. Just a general rule of thumb that the 12" PR mates well with the 10" MKII. They said I could go up to 150g of added mass if I wanted to try it.

    What do you think?

    Code:
    Here are the specs for the MKII 10"
     Fs 28.

     Re 2.467 ohms
     Le 2.48 mH
     Z(nom) 4 ohms
     BL 11.74

    If you have MS Excel, grab a copy of Unibox software (use can google to find it) then do a proper box simulation.

    I tried that, but I get a lot of blank or "#DIV/0" errors. A lot of the fields in the DDBase are empty and I do not know the values for them. I've used Unibox quite a bit and it's great, but I've never mastered adding in my own drivers to the database.
