JBL 4349 or Klipsch Cornwall IV


I need some input on these speakers, I will be able to try 4349 in my home in some time but Cornwall IV is difficult to audition, no dealers nearby. Any input is highly appreciated.

I listen to rock, metal, classical music, jazz, americana and occasionally some country. I have Mark Levinson pre and power (power is not an issue with the JBLs although I might have to change amp for the Cornwalls). My room is roughly 16x18 with a 10 feet ceiling.

I have listened to JBL L100 and while I enjoyed them with classical, jazz and metal, I did not find them to be very good for rock. The treble was slightly harsh and since the loudspeaker did not sound very open or engaging at lower volumes, the treble became very noticeable when the volume was dialled up. But like I said, they brought life to classical and jazz, that’s why I’m now looking at 4349 or maybe Cornwall IVs which have gotten some very nice reviews.

LaScala with subs. A big step up and worth the money. There are good used ones out there also. 
Thanks for suggestions @dave_b and @russ69. I live in Europe so used Klipsch heritage speakers are rare, would have loved to try a La Scala though. 
I’ve now spent two evenings with the 4349 which I have on loan from my dealer. Brand new so they probably need a lot more time before they open up. Impressions so far: 4349 is a better speaker than L100, more balanced and a more refined treble. They seem a little shy in the bass initially, maybe because they are new. L100 had more mid bass immediately out of the box though, bass that was both heard and felt.
Voices are really good, better than they were when I tried L100. Overall a very good speaker. 
Still considering Cornwall IVs though. While I really like 4349 they are still quite bright and I’m worrying about fatigue. 
Not sure if Cornwall IVs are less bright and if I go for them I’ll need to buy unheard. Luckily I don’t need to decide yet, maybe someone has heard both JBLs and Cornwall IVs and can advice? 


The JBL’s will settle down on top and the bass response will definitely become more full and powerful as they break in.  Cabling will be a big factor in getting the best results.  What do you currently use?
I’m using Van den Hul speaker cables (D352). I don’t think they are bright but there may be better alternatives.
