    I need to buy a new speaker for my 15" cab, and I need some advice.

    Anybody ever use a Kappa (not the pro or the LF, just a kappa)

    According to WinISD, that one seems to fit what I need the best, but I don't see that they are used very much at all, and I was wondering if there was a reason why.

    The Kappa 15 has insufficient xmax for bass.

    OK, thank you. In that case I'm looking at the Kappa pro LF, or the Delta Pro. Which of those do you like better? I have a 2X8 with plenty of highs, so I'm rally most worried about adding the fundamental to the low end.
     
  5. Do it the right way: match the driver to your existing cab.

    1 - Calculate your net internal cabinet volume
    2 - Download my spread sheet
    3 - Locate the SBB4 or QB4 cabinet volume that matches yours
    4 - Check the F3 to see if the driver is suitable for your needs

    You can always plug the driver T/S data into WinISD to see what it looks like.

    Go KProLF, twice the xmax, but follow Bruce's advice and make sure it works in your cab. The standard Kappa 15LF is good too, and so is the Delta 15LF if your cab is big enough.

    I did that, and it said the regular kappa was a great fit for my cab, but the kappa pro LF was not far behind.

    The new Kappalite and Kappalite LF are looking good.

    Have you seen specs on the Kappalite/Deltalites yet?

    They're shipping now, I have some. I expect the originals will go on closeout just prior to the new ones being advertised, that will be the clue that they're coming.

    Well then, I guess the question is, should I wait for the new ones to hit the street, or purchase a kPro LF right now?
    Wheich models are being discontinued that you expect will fall in price?

    How can I find out what the cab requirements on the kappalites are?

    I doubt if anything other than the original Deltalites will be discontinued for now.

    I'd wait for the new ones. The T/S specs are on Bgavin's latest spreadsheet (thanks Bruce).

    The old Deltalite 15 wasn't much to write home about. apparently the new ones are much better. I'll have to sit down and do the math before I know exactly how much better.

    No comparison, and a few pounds lighter to boot.

    OK, you guys talked me into waiting for the new line. Will they be called Kappalites, and when should I look for them to be available?

    My understanding is that the Deltalites will be revamped, and the Kappalites are completely new.

    interesting. the kappalite 3015 can be used in a much smaller box, with a slightly higher resonant frequency, but the LF takes a much larger box, but you only get a slightly lower frequency.
    but what an xmax on the LF! 9.6, that's incredible.


    my post you quoted was wondering when the speakers would be available, not the spec sheets
