Network

[paragon]

Just a pic,

Selfmade 4 way passive network for 4530 with 2205, 2441, 2402, 2405 18 dB/O
optimized for flat response at listening place. Not final, only for test !!
Crossovers are 700, 7000, 11000 Hz. Try and error !! But works good.
Very hard to get a flat response of the 2405H (11000 Hz). Both drivers have different network components.

It`s possible to get a very flat response of all drivers, if you have something to measure acoustical output of them.
It´s possible to take all "sharpness" from mid and high drivers.
Had a network for the 2405H, crossover at 14 KHz that was very smooth and sounds so sweet.... only the upper highs very, very sweet and smooth. Sounds like the best Ribbon-Tweeters !
Yust try !!!

Hey Eckhard!

This is something.

Please pull out the electrolytics ;)

This is only for test, Guido. The electrolytics are only parallel to the drivers.
There are no "high cost" caps in this network.
