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.

 @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. 

Maybe the 4329’s were just more musical...hard to figure.  Anyway, good luck!
If you have the opportunity, visit the Klipsch Forum:  https://community.klipsch.com/index.php.  I have several Klipsch heritage speakers and have since transitioned from SS to tube amps.  They are very efficient speakers and for my taste the tube amps were a better match.   I will be pairing my Cornwall IIs and La Scala IIs to Decware amps after much research.
