    I would expect the 476's to work there as well. Maybe some of the other guys can post some measurements. I know 4313B did some measurements on that waveguide with 476Be and they were impressive to say the least. Might be in the DIY 1200 Array thread.

    Hi Rob,

    I have seen 4313B picture of 476 & PTH90 horn,

    http://www.audioheritage.org/vbullet...l=1#post344169

    but never seen any measurements. May be on some other post (if any)?
    May be long throat of the PT-H90 horn would not allow High-frequency dispersion of the 476 driver, but on the other side a kind of
    "soft dispersion slot shape horn throat" would improve horn dispersion.
