    100 kg bass compression driver

    Unlike JBL, the Japanese company ALE Acoustics offers compression drivers for the whole frequency range; see http://www.tachyon.co.jp/ale/ale.html

    Drawback: The listening room has to be rebuilt to accommodate the bass compression drivers.

    This picture is interesting. One can see those big P160's bolted to those huge horns in the back? Or are those the next size down?

    Of course the red pallet not matching the bare brown pallet ruins the whole thing for me

    no doubt comparing the (side by side) sonic attributes of both ...

    Right!, that pallet just CLASHES with the tasteful Louie XV-Jules Verne ambience.

    YGoh, Kevin Brooks can be reached at: brooksaudio*(at)*hotmail.com (remove the stars and parentheses, use @).

    Yes, it is a cruel twist of fate that these otherwise most perfect reproduction devices have long arrival time delays. Some choose to ignore and tolerate them, while others correct them with digital devices. The DEQX unit does the best job I know of correcting the errors with the least degradation of the signal.

    Thanks Steve....

    1.) Can a digital delay in one of the channel degrade the sound?

    2.) Do you still makes horn for different?

    2a.) If so, then which shape do you think gives the least harmonic distortion? it's circular or the rectangular cross section?

    Thank you

    Hello Steve,

    The problem is already at a relatively small horn like my Hartsfield. The woofer has a delay to the Mid-Horn of 3,56 mSec .

    post 74.

    My question, there is no passive crossover with a delay for the midrange and tweeters? I know only the Time Align crossover from Urei, but delayed the bass.

    regards
    juergen
