@chassell, I recently picked up a mixed set for repair.

 

Different motorboards.

 

Same crossovers.

 

Bit it looks like the K-48s are different. One is(was, its trashed) pro vented and the other is the same one used in the Chourus without the vent. Have no idea if this was stock.

 

Do yours have different woofers?

Can someone give me approximate dates? When were KP-301s manufactured? 

 

I believe they started mid '80's right after the CP-1's (pro Cornwall II's) similar in time with the transition from the HIP's to KP-250's. The "II" series didn't start until 2000, not sure if the originals were produced the whole time or not.
