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.

The 4349’s will need power for full performance.  My Krell K300i drove my 4329’s extremely well but they thrived on it.  Cornwall’s will allow you more latitude in choosing amp.  Depends on your type of listening...I enjoy live volume levels occasionally so power is a thing for me.  If low level is your thing then go Cornwall with tubes.
Keep in mind that speaker placement can be the biggest issue between something sounding meh and phenomenal.  Look at Mapleshade free advice speaker placement section.  I’ve been using this configuration for years....best bass and soundstaging I’ve heard.  You can dial in a great balanced sound with minimal acoustic treatments.  No standing wave issues and fewer suck out problems!
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?
Are the 4329’s not available to you?  Less expensive and they have a three way design.  
My gut was to choose the JBL 4329 over Klipsch Cornwall when I was in the market, especially since I was using a high power SS amp like the Krell.  They are rather efficient but also enjoy being pushed when needed.  Midrange was buttery smooth and big with great detail.  Highs were lively and airy without offense and bass was powerfully deep with proper placement.  I think Levinson/JBL combo is a winner.
The “not resolving “ part is most likely due to the Mac equipment!  I owned their high end separates and although they had their positives, I could always hear a bit of a whitish veil over the music.
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.  
Maybe the 4329’s were just more musical...hard to figure.  Anyway, good luck!
