JBL 4367 = Sleep Denervation

I am having a real problem created by the JBL 4367… I can’t stop listening to them. I have been up late (2:00am-3:00am) every night this week and can’t seem to turn them off. I found an extremely good deal on a new pair and bought these blind. They might not even be broken in yet and honestly I am completely blown away. Had/have what I would consider a very good system but nothing too crazy (Revel/Mcintosh/JL, pictures in my profile) and this is a big step change improvement.

 

The texture in the bass is much better than my JL E112 subs. Enough so that I have lowered the hi-pass frequency to 40hz. The highs are the most delineated I have heard. Where other good speakers shimmer, on the 4367 you hear the actual ride and subtle move of the high hat. I have never heard anything like it. The mids are clear like the Revels but seem to bring a sense of power. Everything just has a real feel to it with amazing texture and tone. There is texture in the bass I have only ever heard on headphones or large super speakers. The soundstage is big and stable, actually extremely stable. I hear no box or driver resonances of any kind.

 

Best of all even standard recording music sounds good. Old grunge, metal , 60s classics, 80s pop is good, modern computer-generated music, it all sounds good. Average recordings have dynamics that did not seem to be there before and audiophile music just explodes out of the speaker. While audio memory is short and it is impossible to know I would go as far to say this is the best speaker I have heard for my tastes in sound. I am struggling to come up with anything I dislike in the sound (now we could talk about the looks lol, and why is it so short?!?)

 

This is best system change I have ever made. If you have been curious about this speaker don’t wait and give it a try. If you are looking at more expensive speakers maybe give the JBL 4367 a try first and “save” some money.

I’d wager the JBL subs are the better match with movies as well, even giving up sub 20Hz reproduction, being they likely provide better central bass slam and "bite" while being of the same "sonic cloth" as the main speaker woofers. This is not trivial, and something many overlook. Remember, integration is key.

I agree!

@james633,

A used JBL B460 sub will match well with the JBL 4367's. See below:

I just want to add:

For anyone using the 4367 with standard smaller wattage amps. Please try biamp it. You’d be surprised how much "air", the atmospheric data and details there can be.

I started with a pass lab x250.8, then a single ahb2, then 2xahb2. Then out of curiosity I figure I’d try another pair that was suppose to goto 2nd system.

Absolutely amazing. The realism and airiness is mesmerizing.

I went to THE audio show, and I couldn’t find a system that I think can better my setup, that had never happen before.

So whatever power/current u can throw at it, try and see.

480w@6ohm for just the horn section is absolutely overkill, but everyday I’m at awe to what I’m hearing.

I'm a bit late to this thread but, thank you to everyone posting such great information.

I'm a longtime 4430 user and will receive a pair of 4367's this week to update my listening room. I can confirm how difficult it is to match sub(s) to the 15" JBL driver. I eventually gave up trying to do so with my 4430's. 

Once I get my 4367's dialed in, I'll give it a try again with the suggestions provided here.  Thanks again!

Troybn,

 

Post your opinion once you get them. I thought they sounded good out of the box but feel like the bass improved with a bit of time on them. The highs above 10k seem to sound better on tweeter axis rather than above it so you might need small stands depending on your seat. If you get too high or low the highs roll off a bit. Similar to toeing out the speaker.

As for subs, I don’t think this speaker needs subs, but subs do improve the sound. I have my speakers about 5’ off the wall and highpass to subs at 60hz-ish. Without subs I find the bass below 40hz a little light in my room. For an absolutely seamless sub integration I used a 24db slope on both sides at 37hz. This is a very “audiophile” sub setup. But I enjoy 60hz+ more as I like the slam the sub system brings. Without the active crossover I could not get the subs to blend well (measured/listening). With the active crossover on the subs more or less dropped right in.

if you place them closer to the front wall you can probably bring up the 30hz range but will make a dip in the 150hz range. Just have to play with it.

almost a year of ownership of the 4367 and my day one opinion of them has not changed. I will probably keep them until they wear out. Maybe I will add new speakers down the road but plan to just keep these regardless. I will be upgrading my sub system this spring if I can swing the cash.
