    Iwata?

    Hello Widget,

    Thanks for your feedback. The only producer of the 4003 horn is the guy from Hungary. I would hope that by now he has refined his manufacturing and quality should probably be...

    Horns for TAD td4003

    Hello,

    From those that have experimented with various horns on their TD4003 driver...

    What are the horn options to get good sound from td4003? Clone of original th4003 or would IWATA work?

    Earl K,

    Thanks for the idea. Worth exploring if I can't get the original. However, since you have a single Dukane 5a540, would you be interested in selling it to me? I also have a single working...

    Has anyone compared the 4" Be diaphragms between the 2240-2451 JBL models and if the sonic character changes through the driver models?

  6. Dukane 5a540/Coral -- repl diaphragm recommendation?

    Hello,

    I got a pair of Dukane aka Coral M100 drivers (no diaphragms). Can someone recommend a source of aluminum or phenolic diaphragms that fit the Dukane 5a540 properly?

    thanks,

    Rich, I have the TAD 4002 and I don't really like it either. Too bright, like an arch welder. However, on the JBL 2384 horn, with the...

    x-over freq

    What's the optimal crossover frequency for the 2384 horn mated to JBL 2451be or TAD 4002? Maybe that will help to narrow down the choice between a 15" or 18" midbass woofer? I plan to use that woofer...

    That's one option. Generally, is there a rule of thumb when selecting an 18" that is optimized for upper freq range, like low Le or low moving mass? What should I look for?

    Can you please provide more information on the needed spacer? I will use 2451 CD with 2384 waveguide.

    2451 & 2384

    So far am leaning towards 2451be+2384 or Radial type horn.

    Will I need a spacer between 2451 & 2384 horn combo?
    What is the horn model no from JBL 4367? Is it the H9800?

    Which horns for JBL 2451 Be drivers?

    I now have some 2451h drivers with original diaphragms. My plan is to load them with Be diaphrams and try to make a nice 2-way monitor. 3-way is an option but I will barely manage making a...

    I've thought about the mentioned recommendations and, in place, decided to try the JBL 2451H on the JBL horns (were sold together). Just curious, what's the best source for the Be diaphragms, now?...

    Sample of the phase plug horn

    http://www.funktion-one.com/products/resolution-3-sh/

    Look at the midrange section, it uses a 10" mid. The idea is to keep this concept but adapt to the 100Hz horn with 12" driver.

    I will be removing the alum dome completely. It will be replaced with a big phase plug to reduce the on axis beaming.
