    I have seen several posts by ThomasW about this driver and noticed some of the IB folks using it now. Since it goes for around $140 or so, it looks like an awesome deal.

    Quiestion is: Besides IB usage, has anyone else used it in a standard vented application?

    Quick Specs for anyone wanting to model it:

    PL15D4 (Dual 4 ohm VCs)

    FS 23
    QTS .41
    QMS 6.45
    QES .44
    VAS 2.8 cu ft
    XMax .79inch (20mm, right?)
    RE 6.7
    PE 2000

    PL15D2 (Dual 2 ohm VCs)

    FS 24
    QTS .38
    QMS .44
    QES .41
    VAS 3.02 cu ft
    XMax .79
    RE 3.8
    PE 2000
    LE 92

    I would probably be more inclined to use the PL15D2, that way I can wire the voice coils in series for 4 ohm load for something like a plate amp.

    Any thoughts on suitable enclosure volumes?

    I was thinking, 3 cu ft tuned to 18 hz. I modeled it in WinISD and it looked fairly good.

    Also, opinions on suitable power for this driver in a vented enclosure? I was thinking something along the lines of the Rhymik Audio 350 plate amp. Perhaps more would be needed to really make this driver sing?

    the problem i see what that setup would be the port length. to get an 18hz tune from a 3 cube box with that sub would require a single 4" port (which isnt enough) to be nearly 32" long. that is going to be pretty hard to do.

    You want a much bigger amp. The rated sensitivity is a lot lower than their stated 92dB, a more realistic rating is 86dB

    And IMO, one should use a 6" port with any high excursion 15" driver.
