    Excellent!

    subwoof, what method of shipping did you use? I might have to ship a pair of 2122H's to Germany.

    Hello Giskard

    When the Tent was new I shipped a pair of 3107's to France and Ians 2122's to Australlia. In both cases I used the USPS with one of their express services. In both cases they went off without a hitch. You loose tracking outside the US so if you can live with that it works. Cheaper than the other alternatives at the time.

    News from the project...

    The cabinets are nearly finished. Next week I will begin the installation of the parts.

    Guido measured and tightened the frequency networks that the frequency characteristic to 17kHz runs linear.

    Starting from this frequency the horn within the upper range drops. In the original descriptions the 4430 goes to 16kHz (-3dB).

    From where do the differences come? Did the drivers become better?

    Or is the "A" version of the horn a little bit different to the original? Have does JBL under-floated? I am naturally pleased about it and I can hardly expect it to hear it....

    Original specs were done with the 2421 compression driver running the aluminum diaphragm with the diamond pattern surround.

    Hi Guido,

    I think the coming weekend is a good choice for testing? Even with the four 2245?
