Studio Monitor Bi-Amp PCB
This is a single sided design
you will have to provide +\ - rails with good filter caps
It uses the LM3886
or the or the LM2876
In my application I found 40 watts worked great for the horn
with 68 kicking full range !
Attached is a PDF that you can use to make the PCB
it is scale mirrored
just print it on glossy color photo paper and then IRON the toner on to fresh clean copper for an etch resist !
It really works
radio shack has the Ferric Chloride for etching:
It's like 16 ounces for 9 bucks !
