JBL Summit L300 or Klipsch Cornwall for Jadis ?

It may be opposites attract, but as a diehard Maggie-lover-owner, I have somehow always liked the sound Klipsch classic series. Love the Cornwalls. Go with those.

To add to Macdadtexas post, I am a diehard stat fan and own Martin Logan Summits but have always enjoyed Horns, especially with tubes.

Both are great picks for a "in the room" presentation. If your going to be living with them a long time, pay the extra and get the JBL's, You'll look at that smoked glass top and that beautiful wood and have a nice pride of ownership thing. The Cornwalls will do what your after, so will the JBL's.

Have Fun

Originally I was a stats fan, then I became a horn fan. I have real horns in my main system and Altec Model 19s in a second system. The JBL L300s definitely have the looks going for them. The Cornwalls (and the 19s) are probably a bit more sensitive. The L300 cabinet, besides looking good, is quite solidly built. I agree with Steelhead the L300s will give you pride of ownership. Unless speaker design radically changes, I expect any one of these speakers would keep a great deal of their value. I for one think the 19s, at least at the price I bought them, are one of audio's great values.

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.

I have been studying on which speaker to buy for my Jadis Orchestra Reference

The Cornwall, no doubt. Esp. for your Jadis.
