View Full Version : What were JBL 2235H 15" Speakers used in?

Trying to figure out if the JBL 2235H 15" Speaker was offered in an enclosure. Trying to find a couple for a project and was thinking this might be an alternative way to search for them.

If they were, does anyone have a list or model number etc?

Thanks

My B380 sub had one! Pretty sure they also came in the 4430 2 ways ...

They get traded around pretty well - got a pair from a forum member a few years back for
the 4341s I was modifying at the time (that came used with 2234s).

Once I had the 2235s, I moved the similar 2234s into the L200s in my Avatar ...

might be less expensive to look for compatible frames that can be reconed
(e.g., 2225... there's a vetted list here somewhere)

Other than the already mentioned B380 subwoofer, all I can think of system-wise is
rather expensive/collectible(?) pro monitors of the 43xx and 44xx variety.

Grumpy's right the easiest way is to get a pair of ferrite cores like 2225's and have them reconed with fresh kits. Don't know what the cone kits are going for now but a few years ago that was the cheapest way to get a pair. You can also look for 136H's many of which would have been reconed with 2235 kits.

The only ones I'm aware of are the B380, 4344, 4355, and 4430. Which means, as others have mentioned, they will be expensive and not the best source for parting components.

I asked my favorite Seattle reconer and he said $130 maybe more for the little weight ring gizmo if it's there and "difficult".
I guess my question with regard to the 2225s is how close can you get them to the 2235s ?

Do the 2225s have the weight ring thingy?

Thanks for these suggestions, always trying to figure a way to back into things (probably nothing new)

Guessing that's an aftermarket kit for $130... may not come with the mass ring. JBL kit has it in there.
2225 is same frame and magnet as 2235, so once reconed, it -is- a 2235. ... without the mass ring, it's a 2234.

Your decision on the whole after market vs. OEM recone business...

JBL kit is P/N C8R2235 (same kit for 2234)

I'm probably wrong here but its perhaps a way to go , 2225 , remove the suround and replace with a foam from Rick Cobb , add suitable amount of aquaplas to back of cone in situ.
Tricky task with the aquaplas I suppose but would this not be pretty much where we want to be ??

Don't flame me , just thinking outside the box.

A wealth of information.....

If one had access to aquaplas, something like an S&L woofer tester, patience,
and more knowledge than I about the difference between the 2225 and 2235
progressive spider, one could conceivably come close, or at least learn from
the experience :)

Yeah, the MSRP on that cone kit is $214.

It was just an idea.. I think the coil is longer on the 2225 also ........

Re the Aquaplas did someone not figure out the equivalent qty to make up the mass ring weight ?

On the subject of aftermarket kits I was given a assurance that the MWA product is made on the same jigs etc as the factory parts. ( This from a major JBL service center in this country )

grumpy

wasn't trying to sound too critical :)

I think 4313B had/has posted the mass info and steps
in applying/drying/weighing/repeat. vs. using the mass ring
with the 2235 kit.

No probs Grumpy , as I said I was just thinking sideways.

Actually I'm no big fan of the mass ring in use where the driver is expected to play up to 800-1000Hz. You can hear its presence. In sub use , no probs at all of course.
This from a 2235 user , but I have taken my mids down to 600 ish and boy did that clean up some mud.
I would expect that Aquaplas only might not sound as thick at the HF end of things as the weight would not be concentrated at the VC , which is now trying to move very quickly.

Anyone ever tried adding the mass ring to a 2225J ?

grumpy
03-01-2013, 08:10 AM
I have not, but my understanding is you would be trading off efficiency above ~50-100Hz
(roughly 3dB less), and gaining another 10Hz or so of low frequency extension, ...
with a larger box, tuned lower being required to take advantage.

One could also accomplish much of the same effect by electronic equalization
(excursion limits remain the same with or without the mass ring).

I had 2235s in my 4341s and put the 2234s the previous owner had stuffed into them
into the L200 custom 3-way speakers that are my main JBLs these days.
I think the 2234s are faster hitting than the 2235s - but it is a subtle difference.

Tho I suspect if you could find either the 2234s or the 2235s you'd be happy.

I thought JBL Pro had some 2234H's or 2235H's left.

It appears they might have some 2235H-B left (B stock).

Call Pro Parts and see what is available.

Moving right along now....
Found a pair of 2225s and they are somewhere along the way. Talking to my usual speaker reconing guy in Seattle and he has me looking for the mass rings. I've seen some at "The Speaker Exchange" but they want $34 each for them and they don't look like the pictures I have seen of JBLs

Anyone know where to get the real thing or have any?
Here's a picture of the one they are selling at Speaker Exchange. Never seen that bulgy thing on the side before

bulgy thing is to be removed. If your reconer gets JBL kits, they come in the box.
If not, $34 does seem like a lot for something that often gets thrown away. It's
just a weight. A coil of large gauge no-flux solder (http://www.dkhardware.com/product-29712-2160-60-40-solder.html?mr:trackingCode=2662A810-CDE0-E111-9B44-001B21BCB944&mr:referralID=NA&mr:adType=pla&mr:ad=18074701452&mr:keyword=&mr:match=&mr:filter=40818747372&gclid=CP-cmrPx3LUCFSSCQgodlkwAOw) might work as well.

Well I'm glad you asked that question.....

The wife and I were talking about that over a Martini tonight. I'm retired/disabled and mostly bored. I have always wanted a perfect stereo system.
.....So what is that (the wife asked)?
My best answer is this.... (Martini plus a glass of red).... If you were to be blindfolded and someone played a piece of music, you'd be able to point at the drummer, the bass player, the piano etc. but you would not be able to point at the speakers..... I have heard such systems.

I am cursed with the obsession of making things. That's probably why I became a machinist 30 something years ago. So I have come up with a design that looks good on the computer and would like to try it. If it doesn't work, then I'll try something else. Maybe one day I will get it right, but I hope to have fun trying it, no matter....

Today....
A two way system
2235s on the bottom in enclosures that look good on paper and are made of MDF or HDF
Maybe some 2446s on top with wooden Tractrix horns (yet another project).

I have some CNC mills and a few wood working tools and a lot of time

You just never know

Why are you looking for mass rings?? The 2235 kit comes with them and adding a 35 gram mass ring to a 2225 will not make it a 2235.

Ah I see said the blind man as he picked up his fiddle and saw.

Good project and great reasons for getting started. I wouldn't restrict yourself to the 2235 necessarily , however since you have a plan that involves a large format horn you should be able to use the horn down to 5-600 Hz , to my ear at least this gets you away from the issues at the top end of the 2235's range.
Anyway since Lee has come up with one for you I would snag that and post a WTB ad in the Marketplace section and see what comes up. There will be one out there for you , just be patient.

That'll get you started at least and by the time you get your boxes completed I'll wager you have another at hand. Job done.

BTW all this is a fairy tale and worthless without pics , thats the rules around here. Good luck. M

Incidentally you mention that you have CNC mills to hand. There is a healthy stream of small machining jobs popping up in these forums , you know flanges and so on for obsolete drivers etc etc. You could be the go to guy. You could machine your own mass rings in any case.
I'll bet there would be some take up for acrylic phase plugs for slot tweets. Lots of our boys would like the 077 look.

I talked with the local official JBL reconer (Morgan Sound, Lynnwood) and he says that JBL doesn't have any 2235 kits available but (officially) may have some in May which he scoffed at. The guy I use, Around The Sound in Seattle, says he can match up the various components of the recone to get an aftermarket equivalent, but I'd have to come up with the mass rings. I've used this guy for the last 20 years or so and he has done (what I think is) pretty nice work for me.

Hi Greg. If you want a life-like system, I wouldn't take a 2235 as a bass driver. Instead look for its bigger brother, the 18" 2245. It has more impact. It is basically the same driver, just bigger. I find the 2235 "tiny" compared to the 2245... Just sayin'.
