View Full Version : Elliot Sound Products 2-way electronic crossover

02-02-2009, 04:45 PM
Anyone ever built one of these or know anything about them? I'm a little tired of looking around for a decent affordable electronic crossover with RCA jacks and found this guy's site where he sells laid-out PCB's for this project. I think it would be kind of fun for my first serious DIY. Other advice or thoughts?

What's "affordable?" :) Plenty of stuff out there with either TRS or XLR, and it's not tough to convert to RCA...

One issue with the board you linked to is that it seems like the crossover slopes/points are fixed - not having that control and adjustment of Xover characteristics on the fly sort of defeats the point of actively bi-amping in the first place.

I've built quite a bit of Rod's stuff.Project 09 was at one time on my "to build list". Til I started repairing units.Now I don't really have the time. Built 4 of these for my two 2-channel power amps in my signature..

Rod does a great job documenting his work and his designs seem to be pretty good. The cost of a board is determined by it' size. The smaller the cheaper. The only board I've bought from Rod was the output relay. The component spacing was too tight for me. Solder bridges were a real possibility.

maybe i'll give this a shot, then. i also looked at a couple Rane XOs today, which seem to be very respectable. they have TRS inputs, but i don't think that will be a problem.

how are those DIY mosfets, avionic?
