The JBL 2404H is an ultra-high frequency driver that handles 40 watts program power; Optimized in multi-element, wide range loudspeaker systems w/ response up to 21.5kHz; Unique Bi-Radial Horn for precise dispersion of 100 ° x 100 ° Extended frequency response, high power capacity and high efficiency

Horn type tweeter of bi-radial horn type. By adopting a newly designed bi-radial horn, constant directivity of 100 ° in both horizontal and vertical directions over a wide range of 3 kHz to 20 kHz is realized. It also has the advantage that second harmonic distortion is extremely small due to the rapid expansion of horn flare.

The 2404 is nice if you like wide dispersion in both planes. The 2402 is really for sound reinforcement use. JBL used it in the old days because they hadn't come up with anything better yet. I have all three, 2402, 2404, and 2405. I use in my system the 2404 and 2402, and the 2402 bullet is VERY loud and also beamy.

2021年2月14日 · All three choices are aftermarket replacements - the Simply Speakers one is made to look like an original JBL part, but the fine print says discontinued and use D-2404, which is their aftermarket diaphragm. The other two look …

Now the 2404H has a 105db rating which should make it hotter, it is not. After removing the lense, I found an aftermarket pair of diaphragms. Could this be the cause of the low output? The DCR is about 6.4 ohms which tells me these should be 8 ohm impedance. They look exactly like THESE on ebay with the same number.
