    476Be

    I think we should put an order in for 26 of them, and 26 1500AL's too.

    That is really nice looking.

    Is that anechoic response, or your in-room respons?

    Is there an EDS available for the 476Be?

    I did a bunch of measurements of the 435Be and 476Be on the PT-F95HF, H4338 and H9800 horns over the course of a weekend to get the data for LEAP. I used JBL's method of shooting straight up into the sky with the mic suspended 1m overhead.

    Not when I last checked a few years ago.

    The last two graphs have the 2441 and 2311/2308 added just for fun.

    the 476Be looks really smooth on the wave guide! And this really is without any EQ?
    Impressive!

    Yes, that is without any EQ applied. Greg predicted that it would be very smooth even though he had never tried it himself. I finally got around to testing out his theory.

    Here's an EQ circuit example:

    Did you give it a listen in your dual 1200FE speaker?

    Could that smooth curve indicate that the 476Be sound better on that wave guide than it does on the H9800/H4338 (with proper EQ for both, and only above 1200Hz or so, for comparison) ?

    4313B, do you have distortion measurements for all these combinations?

    Maybe in a couple months I'll have time to do that.

    The smooth curve looks quite interesting. It's a very nice driver.

    No, I didn't have time for that. I just needed some data for LEAP. I have more measurements to take in the future depending on how the projects go.
