    JBL 4367 first listen

    Just got them in today. The large packing containers insinuate the speakers are much bigger than they really are. They are easy to un-box and one person can do it although two is better. The multi-lingual owners manual is about 3/8's of an inch thick although only about 4-6 pages of it are in English. I did not check but finding setup instructions in Swahili toward the back might be possible.

    Fresh out of the box with no break in time here is what I noticed after about of 1 hour of listening. I used a PS Audio Direct Stream DAC, ARC REF-5 preamp and Krell DUO 300 amplifier with the speaker baffles setup about 4.5 feet off the long wall in a 24 x 22 foot irregularly shaped room about 12 feet away. My initial impression was that they were boxy as well as muffled sounding and reserved in the midrange, unusual for a horn speaker. Also a low stereo image. Given that the center of the high frequency horn is only about 33 inches off the ground this did not surprise me. I was concerned about them being too low to the ground from the get go so I expected to have to improvise some sort of a riser for them. Getting them off the ground 3.75 inches (on 2x4's for now) made a very noticeable improvement reducing the above mentioned colorations. My guess is that a taller (TBD) riser will be better yet.

    They have snappy effortless sounding bass with some extra emphasis between 150-250hz (my guess-not measured) that could go away or be reduced with some break in time. Although I did not have time to try it, a position slightly closer to the back wall, due to higher cancellation frequencies, might ultimately provide a more linear bottom end, say around 3.5 feet out. They do not "disappear" as well as the Array 1000/1400 probably due to the wider baffle. In this way they are more like the S4700 or the Everest. Very dynamic and other than the 150-250hz region they sound very balanced and extended. I am guessing that I will find this speaker pretty free of listener fatigue. Some sort of stand or riser will be mandatory with height to be determined by each individual listener.

    One final note. I ordered this pair in the walnut finish which are supposed to come with the dark blue grilles as opposed to the black grilles if one orders the black ash finish. Lucky me I received one grille of each color! So I get to compare side by side before I ultimately chose a replacement blue or black grille. The blue grille has a lot of gray in it. It does not look obviously "dark JBL blue" like I thought it would. Either is handsome. Fit and finish was very good. The walnut grain had more texture and sheen than JBL's walnut cabinets from the 70's.

    More comments to come after break in and more experimentation.

    Thanks for the report!
    What is the height of your ceiling?

    So you listened to them sitting on the floor and then raised them up 3.75 inches? Correct me if I'm wrong, but I'm pretty sure these aren't floor standing speakers. I think you need to get the center of the horn close to ear level to give them a fair evaluation.

    Yes, the horn goes at ear height when seated in the normal listening position. G.T. mentioned that nearly everyone preferred the "4367 slightly better than the 4365". I guess it would be kind of nutty if it sounded worse. The components are definitely less expensive than the 4365 components. 1501Fe versus 2216Nd-1, 476Mg and 045Ti versus D2430K. Regardless, both systems are very nice, especially if one doesn't want to "hassle" with the additional setup required with the M2.

    Sorry to disappoint you Ed. I am out of town for awhile. Imagine 4430's with less butt cheek until I can post them.

    Much much thanks for all the advice, especially the JBL 4367 technical info, graphs etc. What is odd is that I have listened to literally dozens of high end speakers in this room over the last 15 years, many of which also measure accurately, and they do not exhibit the problems I am having. I have not thoroughly read or digested the technical info just posted but I am being forced to consider that some how the 4367's load the room differently than TAD's, Dunlavy's, Wilson's, Revel's, B&W's etc. I am only a wannabe engineer so I have gotten use to being wrong, which is what I am hoping for here. I love everything about these except the bass problems so I will continue to play with positioning or simply try another room. Thanks again........

    Also, I wouldn't start getting too nervous about their sound (especially the low end) until they've had at least a solid week of playing time.

    Screen shots of Audio Control 1/3 octave analyzer show hump centered at 125hz in my listening room.
    I could not improve upon these measurements and maintain a reasonable relationship between the speakers, listening position and walls.

    Walnut cabinets are supposed to come shipped with blue grilles only. I received one of each color, black and blue, so I showed how each look on the speaker.

    I am still looking to find or make the proper stand/riser for them. I realize the horn needs to be at ear level and that the 2x4's are too short, but it was all I had at the moment and I could not wait to hear them.

    I never heard the 4365 so I can't comment on the sound quality differences compared to the 4367's.

    The ceiling height is a suspended ceiling at 9.5 feet as the room is in my audio store. Dozens of high end speakers have been auditioned in this room over the years, so despite it's problems, at least I am familiar with it's acoustics.

    A couple of quick measurements with my Audio Control 3051 real time analyzer this morning showed a smoother response at 3.75 feet off the back wall versus the peaky 160hz range using the 4.5 foot where I started (where most speakers seem to work best). The 3.75 foot position was pretty linear from 50 to 400 hz but with a fairly sharp roll off of 6-8db at 40hz relative to the bass in the 50-100hz region. The overall bass response was elevated relative to the midrange (above 800hz) about 3-4db. I expect the proper height stand to mitigate most if not all of this.

    The loss of bass at 40hz is more of a concern. Perhaps I still have not found the sweet spot for these in the room yet. However I have some concern that the 4367 may have been tuned/voiced for the Japanese market which favors a curve that smoothly rolls off the deep bass at some hinge point in the mid bass. If this is the case, EQ will be necessary for me to achieve the tonal balance I expected. Flat to 40hz is important as it is low E on the commonly used standard 4 string electric bass guitar.

    Interesting!

    The M2 does have the +4 or +5 dB PEQ bump at ~ 22 to 24 Hz if I remember correctly and G.T. has always maintained that his newer systems can use a few dB of boost on the bottom end for the North American market. So a bit of boost on the bottom for the passive 4367 should work just fine. Some folks are going to EQ the system for a room anyway so it isn't a problem.

    Congratulations on the 4367 speakers. Is this real wood veneer, or wood print? As far as the previous comments go, one was talking about the 4365 which is of course another speaker. The other thing is that running in is needed for the bas resonance frequency to stabilise. Looking at the graphs the ports are tuned to 30Hz (the dip in between the two peaks, although the left peak is not shown). This 30Hz seems low enough for a good low end. But I must say that the peak at 125Hz shown by your analyzer is not what one would expect. I can imagine it not sounding as you'd like.

    My experience with having JBL drivers reconed is that they need to move to break-in. As the drivers are much bigger than normal speakers, this means getting the volume quite high. Because before you can see a 15" move, there is some serious bass going on. And 5 minutes is not enough :-) Good luck, hope you get them working properly.
