    There is a process here, and they have to go through that.

    I will probably use D2500Ti in the buyout builds, tho....
    Not really what I was asking... was hoping for an extra datapoint, I'm a practiced designer in my own right. I first mentioned the horn in the context of Econowave, about a year ago....

    Would you mind PMing me some values? I have the 17-25s and some d2500tis that could use some love. They'll have to be refined but would be nice to have a starting point.

    Because these Minis in this thread, some built with buyout components, are presently "under development...."

    Just thought you might have heard something specific as you are more in the loop than I.

    Hiya,

    Ive been loosely following the EW threads for awhile and am getting ready to build soon. I had planned using my Altec 414Zs in the deluxe configuration which uses the DE250 and QSC HPR 152. Now it appears that the QSC is no longer available. So which of all the others would be the best one to use? The cabinets will be built so size isnt a concern. They will be used in a medium to smaller listening space though.

    Re: Flex Your PCD Mettle:

    Yes, good reason, actually -- if both woofers are playing through the midrange, they interfere with each other, and it is difficult if not impossible (other than D'Appolito MTM) to control how they interact with the waveguide and define a forward axis and lobe. There are other means of accomplishing similar performance advantages without generating such issues, but there's clearly more to it than simply running multiple woofers in parallel.

    JBL's approach has traditionally been "2.5" mode where SQ matters, primarily emphasizing the benefit of extending the LF capabilities of higher-efficiency woofers, but they have recently applied their Forward Array Technology (FAT™) to further enhancing performance. We are investigating that in a couple of the Mini E-Wave builds here incorporating dual woofers, TWW....

    Re: Flex Your PCD Mettle:

    So if I may ask an additional stupid question.

    Is there any reason why a dual woofer setup hasn't been used like some of the JBL screen arrays?
    http://www.jblpro.com/catalog/genera...x?FId=30&MID=1


    Its a 3db advantage most of the time adding a second woofer and yeah the cab size doubles but some people are putting these behind screens so there really isn't an issue because we can just go vertical. Plus we get a little bit more extension.


    I am really just thinking aloud at this point.

    Thanks, Steve!

    That be the one, all right.

    228H is the killer 8" for about $118 apiece, but they're not showing that one.

    This also tells us our sponsor here can likely get these on custom order....

    Do you plan to test the B&C vs. the 226J in the standard 2-way version as well?
    Look what I found $79 on line.
