The KP-301 is actually a Chorus I in a pro cab. K48 Woofer, K57 squawker, and K-79 tweetie.
Spec sheet is attached.
301's are great speakers, just like the Chorus.

Never heard them, but love "Pro" speakers. Pretty rare with the oak (?) cabinets ... awesome ... usually they are covered with "rat fur." If I were "local" I'd offer at least $800
Know @rockhound has a pair ... maybe he can chime in
