What is this cross over?

dtfeld

I think I have a set of M5's from 1990. However, I can't find the schematic for what I have...these have a 8um cap in parallel with a 2.7ohm 5w resistor. Additionally, I can't find a poly switch on it.

Can anyone identify this crossover?

Appears to be a Monitor 5 rev 2. The last one they produced. There's no schematic for it.

Thanks Westmassguy. I found a stray wire...any idea what this was from? For a test process or a missing component? Might this be the remnants of the RDE050A?

I'm going to buy a used set of M5 cross overs to get me going until I can get these rebuilt, but no schematic?!? Would be helpful to know...would Polk have that hidden somewhere?

I found it..looks like they installed the guts of a M7 into the carcass of a M5. My M5's internally match up to the M7s_rev2.pdf.

Interesting.

Not exactly, check those capacitor values again.
