    With the 1/8" plates, the "swish" of pink noise became more of a "swoosh." The JBL plates didn't do this and the "swish" was still distinctly a "swish." The 1/16" plates, especially with the higher angle, left the "swish" a "swish" but added the lower range as the 1/8" plates did, more so than the JBL plates. The lower angle added a bit more in the lower range, but took out a bit more over 4kHz.


    I've revised the angle to essentially match that of the JBL plates and will go with that. The overall frequency response improvement way exceeded expectations, and I've not even begun to look at the increase in horizontal dispersion.

    Hi Tod,

    It would be interesting if You can make dispersion comparison of your lenses relative to the 2308 using "lower" and "higher" angled plates.
    Here are JBL data for 2308 horizontal dispersion.

    Regards
    Ivica
