e11even stereophonic 4 way balanced filter network

Here is my latest audio design idea carried out by Phil Marchand of Marchand Elect. No opamps, and fully differential so this infinitely adjustable 4 way active crossover is going to be incredibly quiet.

Killer design, dude! I had a good idea what I was looking at when I saw it, but the detail you put into it is truly awesome. Can’t wait to see her in action.

[@dilbyjones]

Nick Pantazi I'd also like to see the same

[@OCDHIFiGuy]

OCD design for sure. I'm thankful for guys like Phil.

[@edg5367]

I’ll be waiting for it’s test run dude

[@OCDHIFiGuy]

I cant wait.

[@dilbyjones]

This thing is freaking amazing I hope it’s not so expensive that the normal guy can’t get a hold of it because it will e

[@OCDHIFiGuy]

Something this complex is not necessary for 95% of systems Phil has simple 2 way crossovers for around 300 or 400

[@MarcelOoms]

wauw!

[@chrisdomitruk8898]

That unit is frickin bueatiful! Do you use a little EQ in your system? Maybe from 500 hz down?

[@OCDHIFiGuy]

Hi Chris, thanks man.. I do not use EQ whatsoever, I just cut gain on the area in question 48 and below 48 to around 220, 220 to like 2K then the rest up.. I have yet to even hear this piece, its a brand new build and I'm finishing my speaker build as we speak... stay tuned !

[@chrisdomitruk8898]

OCD HI-Fi Guy awesome buddy. I was just RTAing my rig cause I had my Sanders amps rebuilt. That’s Roger Sanders he makes InnerSound flat panels. I do a little eq from 410hz and down to my ATC speakers.

[@joneill1155]

Hey Mike, question. Are all of the high end Dacs you've been shooting out on your channel, can they be Roon endpoints?? Or do they use their own crappy apps to play music? Once in the Roon universe, especially after 1.6 update, there is no going back IMO. Thanks

[@OCDHIFiGuy]

I only have one DAC that incorporates LAN whatsoever. It uses uPnP any app you like. Roon may be great and I use it but I dont like them as a company.

[@jamesstruble1]

OCD, This is beautiful. How does it sound? I am ripping out my Maggie crossovers.

[@OCDHIFiGuy]

I'll have the virgin test run this weekend ! Ask me anything regarding the mod as I've probably been through it. It's not necessary to "rip out" the old crossover you just disconnect and bypass. That way you keep it in place for easy reversion if you want to go back in order to sell or whatever

[@poserwanabe]

How do you adjust the slope ??

[@OCDHIFiGuy]

Modules I solder up.

[@Montreal_Audio_Systems]

have you tred the unit with the op chips before? i would wonder if its worth having the transistors instead

[@OCDHIFiGuy]

That's why I had it built. One of the Pass Labs engineers said they decided not to use opamps due to a slight glare, I will listen to the difference. And report back

[@Montreal_Audio_Systems]

@@OCDHIFiGuy I don't notice any glare on mine on the sublime you could say it had that a little

[@Montreal_Audio_Systems]

@@OCDHIFiGuy I gotta say your crazy passionate and I love the direction your aiming at. It's all about doing it yourself and getting dirty. I love that silver plug you built that's crazy lol. And I also see you like playing with big stuff not whimpy small speakers. I also love when you crank the systems others at shows= whimps compared to you.

[@OCDHIFiGuy]

I just like to have fun.. I'm still a kid at heart..

[@Montreal_Audio_Systems]

@@OCDHIFiGuy which area are you in? U.S I beleive

[@roberthart3452]

awesome product from a proper designer. How about showing the back? XLR for the win. Similar active XOs are $2k++ How much?

[@OCDHIFiGuy]

There are zero rca on this piece. It's only XLR. I'm not sure how to add a pic afterwards..
