RP-160M

Looks like the Full Monty is now $142.20 at Parts Express. I too think more could be gleaned from the horns on these speakers. I'm going to start with the tweeter circuit. Replace the 3.9uF poly cap, upgrade the resistor and add a copper crossover cap. If I hear a definite improvement, I'll go further. I think I can mount these components in the PCB no problem. I pulled out one of my crossovers and it is tight in there, but this stuff can easily be mounted. If not, I'll be out some cash. But right now I'm looking at a $2000 set of speakers to try to get a better sound. These speakers have wonderful sound reproduction in the low and mids. Things start breaking up at the upper mids and highs. This project might not begin for a few weeks. But I'll post the results here.

Figured out the circuit. Made a diagram/schematic.

Bumping this. It looks like Tweaker256 has not been here for some time. My RP-160M speakers could greatly benefit from this upgrade. I'll try to figure out a schematic from his notes and one of my corssover circuit boards.
