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.

My first question would be how much toe in was used. Pointed right at you, the sound can be overwhelming. Positioned so that they cross a few feet behind your head seems to be the sweet spot. And you need to have a little distance between them and you for the drivers to blend.

As for the veiling, I can't answer to that. They seem to have very good resolution to me. There are other speakers that are more resolving and articulate, but those tend not to have the tone, texture and involvement that these do.

@mike_f Totally agree regarding soundstage and imaging, I actually preferred L100 over Dynaudio Confidence 20. They had both height and depth, as well as width. My ears are however sensitive to brightness, this was probably made worse by playing them quite loud. I did not really appreciate their sound at lower volume. 

The 4349 has better midrange, treble is not as fatiguing and they are engaging also at lower volumes. What they do not have is the kick of the L100 (the bass is not as fun) and I also think L100 was more enjoyable with jazz and classical music. No question though, from a Hi-Fi perspective, 4349 is a better speaker. But if I had not experienced fatigue with the L100 that would have been my choice as they are cheaper and fun.

 @dsper I think I’ve seen a similar review on the Klipsch forum. Interestingly, my dealer had a visit by the Klipsch distributor last week. They demonstrated the Forte III and his impression (at least what he told me) was very much the same as yours. I know however that he prefers more analytical speakers so not sure what to make of it.

Ok, first off, the 4349’s or the 4329’s I had are extremely lively and dynamic once run in properly and hooked up with appropriate cables.  The L100’s are not as dynamic overall...must be a placement issue or they were more run in before 4349’s came?  The bass should be palpable once broken in as well...very large spider to loosen up.

The 4349 is in the same position as where I had L100. I have not seen any measurements but my guess is that the L100 has more mid bass output which made them exciting. 
In addition, I read a review of the 4349 where they concluded that there is a degree of compression in the bass when playing loud. This of course limits the physical impact of the bass. 
They are definitely lively, no question about that. Received them just a week ago (a brand new pair) so there will likely be improvements. 
I’ll be able to keep them until the beginning of next week, then I’ll need to decide on whether they stay or if I take a chance on the Cornwalls.
