    But what are you trying to discover by asking about an Onken enclosure which is not an Onken enclosure but a sealed box?

    Now, what conclusion can you draw from these measurements? Maybe i'm not right, but to me they seem much alike, at least until 12000 Hz. What happens above is very chaotic for each diaphragm. It...

    And hitting with a finger will make a fingerly sound? If your horn doesn't ring the hammer will not make it ring.
    It rings so much that anything on it will improve the sound a bit, but it is...

    Hello,

    The Altec horn rings like a bell, it might force its sound to any driver you install on it.
    The TAD deserves a better horn, and can be crossed at 800, even 600, where it will shine.

    You're right, I didn't measure the vertical coverage, i add it to the things i will do when i measure again.

    The Iwata is crossed at 600 Hz in a 3 way system.
    I bought a pair of 2123H and moving to 3way, the horn (Iwata or 2397) is now crossed at 1200 Hz.
    That's why i thought of the 2397 after reading...
