They are very different. I have had both. You cannot use the M2 filter settings for the 4367.
The voltage drive in the 4367 white paper will give you some guiding, but remember that passive...
Hi all,
Pos, I agree that is a very good combination. You can certainly match amps like you are suggesting and I'm probably lazy to want them to match out of the box. You did carefully pick yours,...
-Agree with POS and Widget. When starting new there is really no competition between the vintage stuff and the newer 2216 and alike. And no meaningful price difference either compared to the overall...
Hi all,
I managed to damage one of my SUB1500 subs and pending the extremely limited access to spare parts I need to start thinking about alternatives.
I would prefer dual or four 15" in...
Thank you for the kind words. Its been a fun and humbling journey.
I'm pretty happy for now. I think the odd experience that they kind of "disappears" when playing good material, indicates that we...
Really nice. Lots of effort going in to those cabinets. Always inspiring to see nice builds. I think I prefer the veneer version for domestic use.

Hi all,
I have now had the 4367M (M for Modified 😊) operational for some time and had the chance to develop some quasi anechoic and in the room DSP curves. The room is pretty ok except for a nasty...
Hi,
They may look the same but are different in more areas than coverage.
If you intend to use a 4" 1,5" driver for HiFi use the 6815 is clearly a better choice. It is the wave guide JBL use...
Hi,
Unless you need to play stupid loud you can extend the ports about 1-2 inches and add some EQ to compensate. Those big 18's will be than enough in a residential setting without reaching x-max....
Hi,
Rob, sorry did not mean to imply that you did say that the resonances are audible. Just wanted to make a point in that we, at least I do, sometimes chase to resurrect issues that are not...
Rob, I think you are right but it is probably more or less neglectable today. I recently did a shoot-out with 9 JBL 1,5" drivers on VTX, M2 and 4367 wave guides with many different measures on each...
Hi,
Its not there in a 3ms window so it is room or cabinet.
Btw the 475nd dia has a coated diamond pattern.
Will post 3ms measure tonight.
Rob
Ian, please see attached the measurement of the 2450SL/475ND driver on the 4367 wave guide without any EQ applied. Not too shabby :-) .
The large format 1,5" driver cores really loves the newer...
Ian, the large format drivers on the 4367 is really very nice behaved. There is a humb around 1,5kHz and the normal CD fall off from about 4-5kHz. I put a wide "minus" Bell to lower the hump and a...
Here are some curves for those so inclined
1. JBL curve for 2216Nd-1
2. My curve is similar but a small difference due to cabinet. OBS, composite quasi anechoic curve from several...
Ok, so the 4367M is finished and they turned out quite good.
As mentioned above the streamer is done and in the end I dropped the BSS BLU-USB unit and went for a Toping D10B (USB to SPDIF). The...
Great info and graphs.
A few observations.
I like your "depth gauge" approach but it may be valuable to consider that the outside of the driver is a "cover" which is not always centered and...
Thank you for all the kind words. Now the difficult part starts.
The DSP streamer V2.0 is now operative. I finally settled for a BSS BLU-160 with both digital and analog inputs & output cards. It...
Finally after many years the 4367M's are finally live. Still quite a lot of work on curves but promising.
Today is the first day I play music on both of them. I did build a basic streamer with a...
Hi Dezmond,
I think you should very careful to run the 045's below 4-5 kHz. They diaphragms are very delicate and 800Hz may well destroy them given some power.
Kind regards
//Rob
DerekTheGreat, JBL M2 is capable of about 123db with limited power compression and there is no reason to think 4367 will produce less as they use very similar setup (sans the passive filter that may...
Hi mefisto,
Easy part first, the 5006815 is a 1,5" throat waveguide, so that is plain wrong. I have a bunch of them here. The bolt pattern on the flange is the small JBL 4" driver bolt pattern as...
mefisto, if you look at the data files (pls see below) you can see how low you can go with each driver on each horn. All the raw data is there. No caps to adjust for, just plain FR in different...
Hey Widget,
We should probably make a new thread on your DSP endeavor.
I have had the opportunity to test many DSP and nowadays they are silent if used correctly.
The problem people often...
