Hi there,
I found a pair of beovox 3700 type 6233 at the garbage dump a while back. The woofer surroundings where eaten up by mould but otherwise the looked ok.
So I ordered new surroundings and fixed the woofers. Then I tested them on the same crossover since the other one had a fried cap. Sound in both woofers but no sound in the tweeters. Tweeters tested with multimeter, no reading. The tweeters are SEAS 87H 3ohm. After hours of investigation I figured out from a forum (can´t remember which) that the best replacement was the SEAS 27TFFC. Lucky me I found them on sale the same day and ordered them along with replacement caps and restistors for the xover.
Followed this schematic:
Got it together only to discover that the tweeters where 6 ohms and was very loud compared to the woofers.
The amplifier I use is a Technics SA-5350 and a Rega Planet turntable.
So my question is this: How do design a new Xover filter? It should be 2 way filter.
I used a lot of calculators, but I dont understand in which order the xover, driver attenuation and impedance equalization goes. Should I use 1st order, 2nd order? Butterworth or Linkwitz?
Why not use the real thing:

Cause now I put more money in it than I planned:)
And end up with something that doesn't work.
Yes, at The moment. I am confident that I will make it work. Eventually;)
