Full Range EQ

[Nelson Pass]

I am happy to present you with a project that I did 5 years ago which has served me well since.

• The Equalizer for Full Range Speakers Essentials Kit is available in the diyAudio Store.

That should be a usful piece of kit for those avoiding DSP.

Is it (or at least aboard) hit the store?

Nice circuit, should be useful for us poor souls with shouty, bass shy horn speakers too.

Back in the 80's we built electronic crossovers and included a "bump and roll" to optimize the bass speaker performance. It was just another Sallen-Key high-pass with a high Q. I think we used quad FET op-amps or 4136. The XO were always 18dB. These were part of a sound system deal for clubs or bands. I never made much money in the sound business and left it in ~86.

...or us openly baffled.

Superb! Thank you!

I got to hear the Cube full rangers at Burning Amp. Absolutely the best full range sound I ever heard.

Who can not like really high quality audio tools? Yes i am guessing that the original Pass diy equipment will ”Pass” our good old greedy bunch of tone deaf dudes quality control 🙂👍

This is going to be really fun and useful for taiming old midrange shouty vinyls, mixed by somewhat tone deaf mofos with lots of wax in their ears 🙂

Back in the ESS days I called it the Hump and Bump...

Brilliant! Thank you!

Thanks Nelson! This is genius!

Could use in conjunction with the 6-24 analog crossover if I want to EQ one of the drivers.

Thanks Nelson.

Wow, I'm very excited with a lot of your ASP project
Someday, may be this solution for room correction, is it possible hmm ?

I am currently working on a couple of old ESS electronic crossovers.

ME WANTS ONE!

This EQ works beautifully!

Or it did until the magnet fell off of one of my SEAS 8 inchers when I moved it back into the house. Thankfully I have some others to play with.

 

[Jcris]

Are these going to be available through the diyAudio store?

Yup. That's exactly what I've done with great success!
