    Thanks Folsom...I need to get the passive network made for the 3415 bass arrays first. Then I can start on the horn module integration.

    It really depends.... this is not true if you're going for a traditional 4-5 way system with maximum acoustic gain, in this case you need to be about an octave above the horn's cutoff frequency. OTOH, if you use the slope created by the horn's acoustic gain as part of the xo then you can cross lower but you also have diffraction around the horn so the horn's mouth termination is more important. It depends on the type of horns and drivers used really, but the generalization you can cross lower is not valid most of the time.

    I'm not sure I believe that. Any horn with a tiny bit of throat, before the shape, will increase SPL. "low" is a relative term however. I mean for tweeters at least in this case. Tweeters normal range for crossover is around 1.8-3.5khz, for two ways, sometimes up to 5-6khz for three ways. Gain is very typical at and just below that region from any shape, down to 1khz or so.

    If the tweeters you are using already have a throat, then, no, probably won't see much gain in that lower region because it is already part of the basic driver.

    The gain isn't anything wild, but it allows you to push lower before hitting xmax too early. It's easy to cross the lower you go, as the distance of the wavelength increases so that you don't have to have the drivers as close. For that reason alone, with Rogers new speakers, it is desirable to really push that crossover down so that they different drivers sound like one.

    Now this new unit from JBL Harmon looks interesting and preliminary reports are that the Intonado 24 has excellent sonics. All for 2900.00
