Bit of a tall order, I know. I've found myself needing to become an electronics engineer. I can learn stuff & math usually makes sense to me.

I'll explain a bit more. I'm designing an active sound system. I know the crossover points and the balancing EQ curve, but need a little guidance in terms of application. I understand passive resistance well, the old way of doing things, but boosts and active equalization are different. I've applied for the PurePath application from TI with a description of my concept, hoping they will approve me. Yes, I used the company email haha

Any resources are appreciated. Of course, I'd love to hire someone to do it for me, to be perfectly honest, but it's something I have been putting off learning for years and years. I'm working with a skilled manufacturing engineer. We are giving ourselves two years to create proof of concept, fun times.

 

Finding quite a few resources now on my own haha, just had to look. I'm sure I'll be back with questions.

 

Well, hang on now. Does anyone know where this went? The TI link is dead: https://www.designnews.com/automati...v30-design-tool-eases-amplifier-filter-design

 

Ok I found Xsim, perfect. Rambling to myself aids in my learning process

 

Oh dang it's only passive

Do you need any help from us or should we just let you ramble?

For speaker crossovers a Linkwitz–Riley filter is usually used.

 

A Linkwitz Riley filter consists of two cascaded 2nd order Butterworth filters. This web site (and many others) will design a Butterworth filter for you: http://sim.okawa-denshi.jp/en/OPseikiLowkeisan.htm
Use the value of 0.707 for the Q.

 

Take a look at the forums at diyaudio.com Plenty of discussion there of active and passive and DSP stuff.

I've built a few active crossovers over the years, and eventually settled on a 4th order LR. But there's something to be said for a DSP "speaker management" system, like the Behringer Ultra-Drive Pro DCX2496 (or dbx DriveRack). It could make sense to prototype with DSP, find the filter characteristics you need, then implement them with analog stuff. (But check out diyaudio; you might be able do that with a PC and sound card, or with a standalone miniDSP.)
