I like to know if someone have tech info for 2267H?
can 2267H be used in 2-way speaker?
4313b, did you ever get any info for 2267H?

2267H
FS = 41Hz
QTS = 0.42
QMS = 8.3
QES = 0.44
VAS = 89L
EFF = 1.4 %
PE = 600 W
XMAX = 15 mm
RE = 4.8 Ω
LE = 2 mH
SD = 881 sq inches
BI = 22.64 N/A
MMS = 180 g
Vc = 100mm
Owing to the upper data as 15" driver, it seems to me as mid-bass
over 800H it would start to beam...., look Le=2mH.....
May be if two drivers used, or a kind of bass horn to reinforce LF region....would help

I think at most of this information are wrong
first of all 2267 are 1200 watt not 600 and with all this X-max 15mm the Fs is much lower, more around 30Hz
I was told at 2267 are 15" version of 2269 same voice coils, dual 45 mm
you can see in the information for JBL VTX-S25 subwoofer at 2267 can go very low in frequency close to what 2269 does in VTX-S28

Hi Ari,
As I can see from the
http://www.jblpro.com/ProductAttachm...et_4.13.15.pdf
there are TWO drivers in the box, so drivers mutual coupling is present, second that box is tuned round 35Hz and active EQ is applied
but I can not confirm that the mentioned TS are correct.
From the:
http://www.jblproservice.com/pdf/thi...parameters.pdf
may be more precise data

yes, there are two 2267h in the VTX S25 and also VTX V25 but the thiele/small info are still wrong!
Powerful Low Frequency
2267H 15"and 2269H 18"Transducers
The 2267H was specifically-designed for VTX V25 and
has the same motor structure as employed in the 2269H
18" transducer featured in both G28 and S28 subwoofers.
The result? Four-inch diameter, dual voice coil, dual
magnet transducers with industry-leading AES 2 hr power
handling of 2000 Watts. Combined with uncompromised
Crown power amplification, VTX V25 low section output
is unequalled in its class and G28, S28 subwoofers
provide a solid foundation for high impact, very low
frequency reproduction.
Hi Ari,
Well, how to say, may be Your wishes are on one side, and the explanation, but JBL official TS data are the only things we are on the table, and from them, l don't expect 2267h to be a bass driver of normal user., but it can be EQ-ed, so may be it can be used as sub too, but I do not like such loudspeaker usage.
I do not know how it would work in bass horn loading....
I would not look only the magnet motor structure only, suspensions are important to, may be You can put its TS parameters in the calculation and can seen the results.
I do not know Your application, but for the home listening application I can imagine that 2269 wouldbe better decision, or some old school models sa 2235, (even 2231A as my favourite for smaller box about 150Lit), but not to be used say over 500Hz, a kind of 12inch midbass would be my suggestion up to 1200Hz,.....

I am only curious about the 15" 2267h
my friend have them in his VTX sound system an he said at they sound very good, big and deep bass!
I have no problem with my home audio, I have four 1501Al-1 and 476Mg/M2 waveguides that are waiting on the shelf for DSP system

Hmmm, 1501A, interesting, so 12inch midbass woul be more then adequate, in order to protect nice 476 frm too low frequecy loading, and be protected from 15inch driver beaming....

1501Al-1 and 476Mg work very well with passive network in the Everest models so there should be even less concerned in the DSP mode
the goal is to make the speaker as simple as I can, so first I am going for 2 - way speaker

Yes, You are right that 2way system is nice thing, but I would suggest You to try (just as an experiment ) with midbass such as 2202 ,and after I am sure You will never move back.....

I'm also curious about this 2267, would it be suitable in a 2 way or will it need to be crossed lower?
V25 is a 3way setup with 2267h, 2169h and 2430K, but I was thinking more of a 2 way crossed at aprox 800hz.
It looks pretty much as a 2216 on steoids
I would like to try 2267h with D2430K/M2 waveguide
I have seen pictures of the 2267h coils and it look´s like same length as 2269h coils
yes I would say at 2267h look´s like 2216Nd on steroids

What makes you think steroids are a good thing?
steroids are not good thing for people if that is the questionWhat makes you think steroids are a good thing?
2267h have a lot more X-max than 2216Nd so they are capable to handle the lowest frequency better than 2216Nd
but the question is does 2267h work as good up to 800Hz?
2267h are one of most expensive JBL woofer on the market, it cost 1500 USD each!
For one thing the directivity behavior of the 2216nd is probably a better match for the M2 waveguide thanks to the geometry and material of its cone, as explained by Charles Sprinkle.
Also, while the larger VC surface of the 2267 will surely fare better with high power levels, the special VC wire material of the 2216nd is probably at an advantage when it comes to lower levels (ie hifi or monitoring levels), thanks to its lower power compression.
