Series crossover

[ramiro77]

Hi everyone!
I'm building a pair of floorstanders with 2x Peerless 830875 and Seas H1189. I would like to use a simple 2 way series filter for them. But the problem is that I can not find information about these filters. I would like to be able to calculate them.
I have everything to measure the impedance curve and frequency response.
Can somebody help me with this?

If you are trying to use a calculator, that won't be optimal. I recommend using an optimizer suite. Jeff Bagby's "Passive Crossover Designer" will do them. If you want some practical opinion and such, Tony Gee's site and Andy G's site will help you there:
Humble Homemade Hifi
ARGOS loudspeakers

Or you could ask Dave Rosgaard (daver) right here on DiyAudio. He's one of the best in the world.

That depends if you want a lot of parts in your circuit, Terry. I've seen some of his work where I felt some things were superfluous unless he was using valves. Not that he is incompetent, that's not what I'm saying.

I've done quite a few of them myself.

I don't see any posts from someone with that user name talking about crossovers...but he does go by that on PE it seems.

Rod E has all the formulae here:

BTW Wolf your blog posts have helped me a ton...not a member on PE board but read it a lot.

You're right, it's Dave R on diyAudio.

Yes, but I seem to remember that the overall cost of the parts was less.

It's certainly true that a design intended for use with tube amplifiers can (should?) be designed differently, but then the initial choice of drivers may very well be influenced as well.
