    2x2226 with 2352 and Radian 951 Be

    I’m working on three different high-end speaker systems using JBL, TAD and Radian drivers. I was the head Engineer for Equator Audio and love to use DSP to correct some errors but I believe that using these quality drivers with minimal correct should turn out well. I would like to get your input into my first project here. Project 1 has 2 JBL 2226 drivers with the lower one using an inductor to block high frequencies like the old JBL soffit mount monitors using two 15 inch drivers. Then I crossover to the JBL 2352 mid sized biradial horn mounted with a Radian 951 beryllium driver. I’ll drive the whole thing with two channels of a PDAXPRO3 plate amp with DSP. With the horn having a 1.5 inch throat and the driver having a 1.4 inch exit, do you think that just centering the driver on the horn is good enough or should I turn an aluminum adaptor piece to match them?
    Thanks for all your input!

    Depending on the thickness needed to match the correct exit/entrance angles, you might get away with an extra gasket and some modeling clay in the gap. You'll have to measure/calculate that unless someone here knows.
    Ultimately, you don't want that step/discontinuity.

    I like that idea.

    At high frequencies that step will likely affect the frequency response. Modeling clay is certainly reversible and will let you experiment with different slopes.

    Do you have measurement equipment?

    Yes, I have a couple of different sweep systems. If it causes a simple recursive frequency response problem I can fix that with an IIR filter but if it causes a polar pattern problem like a bunch of lobes then I can’t fix that.

    From my experience it is always better to fix problems with physical solutions before resorting to electronic corrections. Correcting a room issue or a design issue has always given me a superior final result than relying on an electronic fix.

    I am not saying that electronic corrections are not powerful and often quite helpful, but if you can use less, the results in my experience are always better.
