    JBL old school sound comes back!

    That is 4367!

    I listened to it carefully at local dealer shop, very impressive,the bass goes deeper than 4365 and very pounchy and rapid.

    Only one question: how to crossover it using outside DSP?

    Where's the UHF driver?

    Ha. Good eye. Maybe it's like the 4430s. Two way with pots for adjusting two bands on the compression driver.

    The question really, as Ed recognized, was why the UHF and HF pots on a two-way system?

    can it be that each pot hit a different frequency produced by the same driver like 8k and 16 k ?

    You guys are not really having this discussion are you? Look at the Altec Model 19, the JBL 4430/35, and others... of course the EQ controls are tweaking the network to modify the frequency response.

    I agree with you Martin about the aesthetics of the M2, but the purpose of the 4367 is to have a passive crossover version of the M2, so trying to defeat the design and going the DSP route is going to require a major hack.

    I have a 4365 and the pots look the same as the 4367 in the picture. With the 4365 you can see two separate HF sections. It just appears odd to see two adjustments with only one horn......most likely works well however.
    Careful man, there's a beverage here!

    Every time I have a seniors moment I wonder about this stuff too.

    But then again my wife says I was born the day I met her...LOL

    It's the same as the older 4430/4435 but the range of adjustment is quite narrow.

    There is an HF presence control and an HF brilliance control.

    This allows slight contouring (or voicing) of the important upper mid range and hf extension to your environment and preferences.

    Its fine tuning only as these controls are full not variable but fixed switch increments.

    GT generally does this sort of thing for a reason.

    My take is he probably found that listener preferences varied in terms of setting up a fixed voltage drive for this network so he incorporated fine adjustment.

    I wrote to JBL technical support asking what frequencies were adjusted by both pots and I got a response but forgot where I stored it! Nuts!

    Hang on.... I'll search some more files...
