At minimum, you need some kind of summing circuit, whether that is an opamp or a simple resistive summer; otherwise, they will fight each other.

Potential compounded stupidity...

Can the output buffer play a role in the afore mentioned summing, feeding both signals thru the one buffer?

I'm way out on a limb, way past my comprehension of electronics on this, sorry.

I'm starting to get my head around what is needed to sum two crossovers. It's a mixer, without all the knobs. - Thanks -

Parts list as word file here : Partslist

It's the best I can do. Tyler has an excel file with values.

Tyler could you post it here?

All of the parts seem relatively easy to find, except the 1uf cap in the 5mm size in polypro. I can find the other three values, but I am only finding PE in the 1uf. Any mfgs or part numbers would be appreciated.

The 15.2K resistor looks like it can be arrived at by a 28K and a 33.2K in parallel. Gets ya' to 15.19K by my calculations.

PE is just fine.

as Jens said, PE is just fine. as for the resistors, i use vishays in my stuff, and mouser has vishays in 15K range, just get a few extra and since they are 1% tolerance, you should be good with 15.2K. i needed a 120ohm resistor before, so i just got a bunch of 121's and tested them out to 120 ohms.

btw, you still need to email me so i can send out some batteries

Hi,

I sorry but there is an error in the partslist. All values are correct, but the position is wrong....Please use the list in the manual I'll change til partslist ASAP

Sorry for any trouble this may give you

Thanks to Bryan Pederson for bring this error to my attention.

I think the list is ok now, Bryan please report back when you have had time to check - thanks
