I use to own for several years the pro speakers one grade up from the Summit 300's, the JBL 4343 Pro 4 way Speaker.
It used essentially the same drivers as the Summit 300's
except the 4343's had a special mid bass driver in its own enclosure and the woffer was sealed offf from the rest of the drivers as well. The speakers were so real huge dynamics lifelike midrange to die over and I'm sure with a tube set up u would be smiling ear to ear,and funny as I'm thinking about it I am now going the SET route in my system and wish I still had these big mosterous speakers again from 30 years ago. I'm not even sure if I have old photos of them I'll need to look around. AND Yes the Summit 300's look much better then the 4343's.
