Please help design a passive network.

[Don Mascali]

I would like to add two 2404H tweeters to a 2380/2446H 2" horn. This would be per side on a portable DJ setup. Can someone suggest a low order network for it?
I don't have a clue on how to add two tweeters, I do have a D75A crown amp and room on an active Xover but I would like to keep it simple.

Thanks for looking,

if you don't want to build it, yamaha has made some 7KHz and 8KHz units that can be sometimes found for relatively little outlay....

you could also just clone the JBL implementation...


if you are looking for really low order, I think you could simply parallel a cap inline...
as mentioned here...

there is another schematic further down in the referenced thread also....

See the data sheet for the 4770A.

Thanks Ruediger, That's perfect.

Thanks Ruediger, That's perfect.

The 4770A requires an actice crossover between the lows and the mids.

The 20 uF capacitor seems to be a protective means against "plops" from the amp, not a frequency-response determining component.
