JBL 4367 shoutiness remedies?


Hello all, I am a first time post-er, so pardon me if I am clumsy with this venue. 
I live in a small town on an island in SE Alaska, and do not have immediate access to anywhere locally that sells hifi equipment besides Walmart. So after reading complimentary reviews, I ordered from USA Tube Audio a pair of JBL 4367 speakers, ..a two way design  with a woofer and a horn. I have about 20 hours on the speakers, driving them with a Primare I35 Integrated Amplifier and a perceived higher end Primare CD player., and for an alternate music source, I use Music Choice from my cable box. I also have a 10 band graphic EQ to tailor the  sound to my liking. The issue I bought when I paid for the speakers is a  loudly blaring shoutiness in the range of frequencies of the human voice. It can be loud and overpowering even with EQ attenuating the frequencies between 500 and 4khz. I called the dealer who I bought them from for advice..he told me the amp and cd player are junk, ($6000 junk) and the only way to fix the shoutiness was to buy tube equipment.  On some recordings, the speakers sound wonderful, but on some, it makes me question whether or not they're worth keeping. The room in the apt I have them in is about 15x18 with low ceilings. Does anyone have any practical suggestions or ideas on how to remedy or at least partially correct this issue? Thank you for reading.

Just based my on experience with a different 4 x KT88 amp, I believe quicksilver monoblocks will likely not help. I wanted to enjoy the VAC but the woofers were badly controlled in comparison to the compression driver, no matter the tap used. The lower midrange and down was disconnected and HF were overbearing. It was an obvious problem even without comparison to another amplifier, which prompted me to a fairly affordable, safe-play Levinson amp. The ML fixed the issue, although I would love to try a high-power tube amp. There may be something I am missing as I never actually heard Quicksilver amps.
Speakers are so dependent on placement within the room it sounds like it is a 2 fold problem - the room and the placement. I have experienced similar problems with my Linn speakers. One thing that I would suggest trying is elevating, slightly, the front of the speaker so it is slightly focused upward and, alternatively, elevate the rear of the speaker so that it is now focused slightly downward. I have found that slight positioning changes can have considerable effects on the way a speaker sounds. You don't say what coverings you have on the floor i.e. a rug, bare floor. I would also try placing a large area rug in front of the speakers if you don't have a rug. If you do have a rug, an area rug over the carpeting may also be worth a try. I do think focusing, slightly, upward or downward plus treating the floor in front of the speaks may help resolve your problem. Good luck. Welcome to the PIA problems that keep us involved with this hobby/second job.
As a proud and satisfied 4367 owner I’d like to add my thoughts. First off, I’m a deadhead so there’s that. I mated mine with Mac / MC275 Mk V, C2300 and MCD500 used as both a CD player and DAC for my Bluenode2i. I also run a Rel 7ti as I like musical bass. Think Phil zone. The Mac equipment was purchased used over time from Derek at audioclassics for about the price of the speakers. I also have a VPI turntable and Panamax power conditioning. All interconnects are from bluejeanscable. I mention these two sites as they are the best value for the dollar and run by honest and cool people.


Plus 1 for toe in from Duke and more is more for rugs, drapes and furniture.


When you decide to go tubes, hit me up as that is a journey unto itself.
JBL uses a JBL HDI waveguide not a CD horn never been a fan of CD horns and HOM generation to produce high-frequency off-axis. 

Not the speakers.  EQ?  Really?  That alone will screw up the sound.  Cables?  Power cords?  Placement?  Need a pure clean signal.
