Series Crossovers

[servicetech]

What do you guys think about them?
I tried a simple 6db/octave on my last project and it turned out pretty well.

I used one on some HIVi driers I used in an MTM I liked it a little better than the parallel XO's I had used on the same drivers and cabinet. I couldn't pin-point why, though. It wasn't a 1st order, I think it was 2nd order LP and 3rd HP electrical, LR4 acoustic. I spent some time matching each components value and making everything neat and tidy

I'm just a novice, hopefully someone more knowledgable than I will share

I think far better of series crossovers than I do any drivers "capable" of 6db/octave. There are interesting challenges with them that are different from the classic parallel crossover, particularly (I think) about what is effectively insertion loss. Not sure.

Jon doesn't seem to pay much attention to series or parallel, some of his are some sort of hybrid.

I've done some series alternatives and always end up with lower sensitivity, which backs the insertion loss thoughts. They're probably best suited to lower order slopes, but drivers capable that are about nonexistent unless you accept quite a bit of distortion in the driver(s).

If you haven't seen this before, it is an interesting read.

Jon doesn't think much of pure series crossovers...his hybrids are used primarily when the idea is to keep costs down.

John Kreskovsky did some sims and measurements and found no difference between series and parallel networks as long as the net transfer function to the driver is the same. That's the big if of course.

a series crossover ?? you mean like an inline RCA crossover ??

[cjd]

google is your friend.

traditional crossovers are separate for each driver and wired up in parallel.

A series crossover is one homogenous mass of confusion (for most folks) and all the drivers in a system are wired in series, with all the crossover components interconnected in some way.

woa crazzy...

I've never built one.

I've played with them on the computer. They seem interesting, but I don't really see a strong reason to build one.

I can think of one reason: It is impossible to bi-wire them. :rofl:

Very true... Very true...
