I have one, got it for $25 at ebay- new!
Question is, the PE mag advises 2.8 cu ft for a vented enclosure.
I use WINisd (had to plug in the correct data for this driver), and am having a tough time finding a small enclosure that will produce good sound ->deep and smooth. I was hoping that I could get away with a 2.0 cu ft box.
Any suggestions or experiences? Seems vented is prefered rather than closed box design....

For 3 cf, WinISD shows an F3 in the upper 30's sealed (which shouldn't be TOO bad), lower 30's with a 3"d x 20" port. I agree with you that at 2 cf, nothing really looks too great. At that size, vented is only a few Hz lower (with a 30" long 3"d port, which is probably so small that it'll chuff), but the sealed Q only rises to 0.80 (0.76 stuffed). That'd probably be my choice.
3 cf, 3" vent, at 2 cf I'd just go sealed/stuffed.

I just found my latest edition of the PE cataloge and now it shows that a sealed enclosure is okay. In previous cataloges it was not recommended.
Some of the specs in the cataloge are incorrect, so PE must change them (Fs, Qts, VAS for starts).
I have also read in other forums that closed may be prefered due to the Qts; a vented box being too boomy....
I have calculated a 1.8 cf box with Qtc of 0.85 and F3 of around 41Hz. Rolloff is smooth, and being a 0.85 Qtc, it wont be too "damped", like with a 0.505 Qtc. Had that experience before, deep but, well, just deep.
So I'll give that a try, if it doesnt sound right, I'll just build another box and put a new driver in the first one!!
thanks for the input!!!
