Jbl 4367 ? .....

[joeinid]

Anyone know anything about these new speakers? They should be shipping very soon.

[joeinid]

Thank you Don!

[Audiobeer]

Can't wait till someone here has heard them just to see what their observations of them would be compared to the 4430s' at 7 X the cost (Street Price).

[4313B]

$2,196 in 1981 → $5,975.05 in 2015 so probably only 2.5x the price?

The components in the 4367 are night and day better than the 4430 components from 1981 but it did take JBL thirty-four years to get here from there.

[jpw]

I just ordered a pair. I used to own a pair of 4430's and will be interested to see how much improvement there will be with the 4367.
I am hoping for more extension a both ends of the spectrum, flatter response, less stored energy and better clarity and detail.

Nice. Looking forward to your feedback.

What do you mean by 'less stored energy' ?

[joeinid]

Hi John,

Absolutely looking forward to your thoughts. I was considering the M2's and now I think these would be better for me and my setup.

Please keep us updated.

[bubbleboy76]

I wonder if they put in the same amount of work with this horn, with iterative real-world tryouts, as the M2 horn? Or if it is just roughly using the principle of the M2 horn. Look-a-like to sell more?

[4313B]

I would imagine so. The 4367 horn is a little bit more expensive than the M2 waveguide.

Yes.

[baldrick]

They looked smaller than I expected, are they quite a bit smaller than 4365?

[bubbleboy76]

Yes.

Can you PM part-number to me?
It would be cool if my 4365s could be upgraded with this horn. But probably the size differs too much, I guess.

What is that?!
The successor to 4429?

[bubbleboy76]

Did Greg work on 4367?
Maybe his final crossover design?

According to the picutre text it is 4367...

[bubbleboy76]

Maybe thoose guys are NBA players?

Phone cameras often distort the picture, so things to the sides looks bigger than they are.
I always try to get in the middle of phone camera pics, it suits my body size better!

Yes, it is smaller than 4365 overall. It is 110 milimeter shorter in height. I just measured and to me it is huge difference. Well, well.....as long it sounds good:)

It is shorter in width as well. Around 40 milimeter.

[4313B]

It does seem small in that photo. I guess the 2216Nd-1 has a smaller enclosure volume requirement, I don't know the volume of the 4367 yet and didn't do any math, so it is just a guess.

[caladois]

Sized similar to the 4338 so !!!

Back of the napkin says 8 ft box based only on external dimensions. I have no idea of panel thicknesses or driver displacement. 4430 (by the same fuzzy math) is 7.3 external which I think we know comes to around 5 ft once all is said and done. Interestingly the 4367 weighs about 8 lbs more than the 4430 even with that neodymium and smaller comp driver. Maybe the panels are thick?

[jpw]

Warren,

Less stored energy = better waterfall plot hopefully through better braced cabinet, less horn vibration and more linear drivers etc.
Should not be that hard to do compared to the 35 year old 4430.

[4313B]

Did Greg work on 4367?
Maybe his final crossover design?Yes. It was his final project before being fired (Harman is stating that he retired which is patently false). I couldn't help but notice that Sean Olive posted a link to a new Engineering intern position a day before Greg's "official retirement date". That position has already been filled.

It would be cool if my 4365s could be upgraded with this horn. But probably the size differs too much, I guess.It is a Harman Luxury product and therefore REALLY tough to get. They have zero interest in running "extras" of any transducers or other parts like horns and selling them ala carte, hence no upgrades from the DD66000 to DD67000 for example.

In any case, I think you are quite good with what you have. I think going forward we are going to see a "cost reduction" trend wherein Harman tries to squeeze the best possible performance out of lower cost components rather than building top shelf components like the 476 or 1500 that have inherently superlative performance.

Interesting, thanks.

Do you know if 1200fe is "luxury", or possible to buy?
Sometimes, I have unhealthy thoughts at night... To build something DIY looking a little bit like the Timber Arrays, with M2/D2 (not R2/D2), 1200fe and 2269h. Separate box for each transducer, as small as possible, just placed on each other.

[4313B]

Do you know if 1200fe is "luxury", or possible to buy?They are from Luxury and have been unobtainable for years. It took me a year and a half to get a replacement for a broken one and that was several years ago.

The 4-inch voice coiled 2206H is arguably the better bet. The extra 3 to 4 dB efficiency is nice.

[bubbleboy76]

what about the light pro neo diff-drive 12" 2262h and 15" 2265h, how do they stand compared to the 2206h respectiveley 2216nd?
light is good for me, maybe want to wall-hang in a future HT.

There is something to be said for the light weight transducers. :)

Hi bubbleboy76,

I would expect them to be very good mid-bass drivers, as they are 3-inch voice coil design.

http://www.jblpro.com/ProductAttachments/technote_v1_n33.pdf

Looking at the 2206 FR curves, it seems to be almost perfect flat response without any response large peaks and deeps,
so I would expect it to be easily incorporated in the system.

I think that 2242, 2226 and 2206 are on one side [ JBL Technical Notes Volume 1, Number 22 ]

and 2268, 2265 and 2262 and not to be forgotten 2269 for the bass section, on the other side.

It is known that Nd magnet is more sensitive to the higher temperature (loosing its strength) , while ceramic can be 'recovered' while become cool.

Not enough rising response and/or distortion output for them. I think D.B. designed it. The guy absolutely knows his stuff... I believe he did alot of the neo transducers too.

[hlaari]

2206 and 2262 are very good mid bass drivers I have play with 2262 for some years ago

what about the 10" 251J?
that driver look´s very good on papers

My JBL rep says my 4367's will ship the end of November.
Others who ordered first may get theirs sooner.
So December sometime before I get my hands on them and can give any feedback.

McIntosh is a perfect match for 4367. Power rating is perfect as well. Connect it to the 4 ohm tap and run in single wire and be happy! It is allready bi-wired inside the speaker:)

[joeinid]

My thoughts too. I am excited for everyone's opinions on these speakers and while I lust for MC1.2KW's, the MC452 is more likely in my future unless someone talks back into the MC1.2KW's :dont-know:

Hallo!

I have lookt at the new Mcintosh and to me the MC302 seems to be a good match for the 4367 if looking that the 4367 has 300Watts(RMS) at 6 ohms.

So, it means

Watts x ohm Squareroot = Volts

300x6 Squareroot = 42.42Volt
600x6 Squareroot = 60Volts This is the maximum voltage this speaker can handle.

So, connecting higher power will give more voltage drive to the speakers and be careful with the volume knob.

[joeinid]

Does anyone think Naim could be a great match with these speakers? I had a Supernait2 integrated and miss the Naim sound. I was thinking about going higher up in the Naim line as another flavor to what I have for these speakers should they prove to be as good as we hope.

Thanks!

Bump,


Anyone have their pair of JBL 4367's yet?

Nope, but I've inquired about the 2216Nd-1 if that counts ;)

I too have a pair of 4367 on order. My dealer said he will receive them no later then first week of December. They will replace my L166 Horizons of which I am the original owner. I will be driving them with a Mcintosh MC302 amp and C50 preamp. Can't wait!

I have a McIntosh MC302 and it is my understanding from the manual to tap in to the next higher ohm that is closest your speaker so the 4367 should be connected to the 8 ohm tap. The amp is a beast to move so I would like to get it right the first time. I welcome opinions. Thanks!

Looking forward to reading more about them. The JBL 4367 and Revel Salon2 are on my short list. I know, different speakers, but I already love the Salon2's and dying to hear the 4367's.

Having owned specialty audio stores most of my life in Iowa, I have had extensive experience with many brands of amps that use output transformers. In general I have found that if you are on too high of a tap (8 ohm tap with a true 4 ohm speaker) the bass will be thin and somewhat under damped and the overall balance can lean unnaturally bright. Conversely if you are on too low of a tap the bass will be muddy, dynamics will suffer, and the treble will sound closed down. When the measured impedance of the speaker isn't clearly 8 ohm or 4 ohm I agree with the next higher ohm tap choice. I will be using MC-601's and a C-48 for starters when my 4367's come in.

[jpw]

joeinid,

We sell the Revel Salon's so I will be able to do this comparison. Like you I can't imagine they are much alike. The Salon drinks amplifier power. I have had the power guard anti-clipping circuit actuate on a McIntosh MC-452 (a very conservative 450 wpc) at levels that are only what I would call moderately loud. Still I love this speaker for it's clarity, neutrality and especially it's linearity through three octaves of bass into the lower midrange. The vast majority of speakers foul this area up. Also very little metallic sound despite metal domes. It still compares very favorably to the latest efforts from B&W, Magico, ProAc in the same price range even though the Salon 2 is well over 5 years old.

Thank you for the response. Just to clarify, you are in agreement that I should connect the 4367 to the 8 ohm tap. Thanks.

[joeinid]

Hi John,

Thank you so much. I love the Salon2's and know they are very power hungry. I love McIntosh on the right speakers and I am not sure the Salons are right for McIntosh. I have not heard that pairing enough.

I totally agree with your assessment and would take the Salon2's in a heartbeat over most of the speakers out there today.

I finally had to give up on my TAD CR-1's. I know many still aspire to own them and many love them, but I could not take the tweeter long term. For me and my taste, it was just too forward. At low volume where I do most of my listening, they were stunning. Crank up the power a little and the tweeter was too sharp for my taste. Others will disagree, but I could not find an amp/preamp combo for the TAD CR-1's that could make me love them long term.

I am anxious to read your findings on the 4367's (as well as everyone's opinion) and sincerely appreciate your participation here. I am sure the 4367's will be easier to drive than the Salons and make the most of some of my lower powered tube amps.

I so wanted the JBL M2's but never made the effort to hear them because of the needed setup, dealer involvement and necessity to use the Crown or Levinson amps unless I use the other crossover option (the name escapes me right now).

As long as the tweeter is not forward like my previous TADs, I think the 4367's could be my next pair of speakers in addition to my Strads.

Thank you to all who post their opinions on the 4367's..

Joe,

I agree the TAD CR-1 could be perceived as balanced a touch forward in the treble, not a peak at one frequency, but over a wide range. During speaker seminars years ago at my store with Andrew Jones, I found out possibly why. Unlike most audiophiles, he does not choose to set the toe in on the speaker to have the sound from both speakers intersect at or slightly behind the listeners head. He sets them with even more toe in so that they intersect well in front of the listeners head. With this arrangement it means that your ear is likely less on axis with the tweeter/midrange and so the output is attenuated over this region slightly. Presumably this would have been taken into consideration when he designed and voiced the system which would account for a more forward sound on axis. Also I found they worked best in a well damped, less live room.

MAC amps sound very good on the TAD's which have a pretty linear well controlled bottom end. Tons of damping factor not needed.
MAC amps generally have a slightly more tube-like softer top end too. Likely the output transformers.

[joeinid]

Hi John,

Thank you so much for your thoughts. I agree on the setup and even with the tweaking, I could not shake the feeling that my perceived forward tweeter was mildly irritating at best.

My current speakers, SF Strads are just wonderful to my ear and while I don't need anything else, having another flavor is always fun and the 4367's could be the ones.

Hallo!

According to manual of MC302 on page 8-11 or "General Information" Note 3 page 3. Particular this info is good to know.

If you have an Impedance, in this case 6 ohms, it say's "If the Loudspeaker’s impedance is in-between the available connections, use the nearest lower impedance connection".

I would connect it at the 4 ohms tap. It will be more balanced between bass and horn.

I know, I had MC252 and the 4 ohm tap sounded best driving any JBL I owned at 6 ohms nominal impedance.

Is there a PDF with the crossover design for the 4367?

[audiomagnate]

Is there a PDF with the crossover design for the 4367?

Ii's not a schematic, but here's what it looks like. Are those diodes protecting the D2340K?

[Odd]

I think the diodes are for Charge Coupled the crossover.
Have not seen drawing of the 4367 crossover, but Charge Coupled with diodes are used in other JBL filters.

That makes sense. It also explains all the capacitor pairs.

[4313B]

There should be a low pass board and a high pass board. G.T. designed them so they are definitely charge-coupled. :)
The HF board is ~ $325 and the LF board is ~ $280, both unobtainable.
The horns are ~ $390 each, also unobtainable.

Then I'm guessing, if the photo really is for a 4367, that this is the HF board.

[4313B]

That would be my guess too. The LP probably uses some pretty large inductors. My guess from that photo would be one coil for the HP filter and three LCR notch filters across the D2430K/Horn.

That's odd. How could a design with completely different drivers, horns and cabinets end up with the same crossover? That doesn't make sense to me. Similar sure, but identical?

Don't know if "same" means "identical" to you, that was not what I meant.

I was more thinking of charge-coupled.

What, if anything connects to "A"? These newer charge coupled crossovers don't have batteries anymore, correct?

[JuniorJBL]

It looks to be a self powered, bypassed, C'Ced low pass. Pretty cool if you ask me. :)

Nope. No more batteries!

Happy Holidays to all at LHF!! :xmas:

[bubbleboy76]

This self-powering, does it require some volume-level to work?
My stock 4365 required some pretty high volume to sound good. Not so with active crossover.

Happy Holidays to all at LHF!! :xmas:

But what is connected to "A" in those schematics?

You connect all "A" together.

The voltage comes from the LF section.

This self-powering, does it require some volume-level to work?
My stock 4365 required some pretty high volume to sound good. Not so with active crossover.

Yes. The XO gets the power from the output of the amplifier.

Any idea where to find the white paper that guy here (http://www.avsforum.com/forum/89-speakers/2243554-jbl-4367-consumer-version-m2-pro-monitor-new-specs-white-paper.html) is talking about?
I would be curious to see those power compression curves...

I don't have this problem with my 4365 stock network. Does not require high volume to sound good, sounds pretty good at low volume level as well. Of course, it depends what amplifier is being used.;)

Here you go!

Happy Holidays! :)

Thanks for the tech info.

What does the JBL 4367 WX and 4367 BK stands for?

BK is probably the all black version, and WX the traditional wood/blue baffle.

Here is the official white paper, as posted on the AVS forum (http://www.avsforum.com/forum/89-speakers/2243554-jbl-4367-consumer-version-m2-pro-monitor-new-specs-white-paper.html#post39907130).

[audiomagnate]

If the crossover isn't getting enough current from the audio signal at low levels to work properly, can a battery be added to the circuit, like in the original designs?

Thanks, let's start freak out over the curves now! ;)

It would be interesting to hear your reflections/thoughts about this information.

I would like to see the spinorama-diagram. The almighty 4313b has it?

[bubbleboy76]

The UHF area looks much better than 4365, from what I remember. But still not "M2-perfect", right?

[bubbleboy76]

I am tempted to do an power-compressnion measurement of my 4365s as a comparison, or is it out there? 4313b?
Is it possible to measure power-compression correctly in-room?

[audiomagnate]

...But still not "M2-perfect", right?

But that's to be expected. I'm actually surprised it's as flat as it is, The rolloff in the 2340 was taken care of, and the dip centered at 11 or 12 K it tempered slightly, but that has to be audible to someone with decent hearing.

[jpw]

The dip around 11khz is about 4-5db relative to the frequencies on either side. Dips tend to be harder to hear than a peak of the same magnitude and at extremely low or high frequencies errors are harder yet to hear because of the ears declining sensitivity. I would venture to guess that the combination of the 11khz dip followed by the peak at 15khz would be heard as a single characteristic. Due to the high frequencies involved I would consider this audible under some conditions, but still a minor flaw.

Hi ,
are T/S parameters available for 2216Nd-1 or EDS?

Thanks,
Zeljko

I'm also keen to find an Engineering Design Specification sheet for the 2216nd-1

There is one around for the 2216nd, but not for the variant used in the 4367 it seems.....

Can anyone help out??
