I have a pair of old JBL 2205A, and it's hard to find the recone kit. My question is, is there a similar JBL recone kit that would fit the 2205A, such as the 2235 or similar.

That's correct. Just to highlight the note about the E-130/E-140 using a higher flux density magnet structure at the bottom of the table. Not that you would use those kit's. Check with your local authorized JBL support for availability.
Depending on how hard the speakers have been driven you might want to verify flux density in the gap as part of your re-cone Alnico's can demagnetize if over powered.
If the flux is low it will effect the response in line with the highlighted note.
Unfortunately almost, if not all of those kits are NLA. They have run 2234/2235 years back if you can find them.
Good Luck!

I don't know which one to choose, so I ask which recone kit you would choose here on the forum for a pair of old 2205a baskets. I think of recone kit jbl 2225h or 2235h (without mass ring)What is your first choice?That's correct.

I would choose 2234 which is 2235 without the mass ring. Good bass and nice mids.
2225 vs 2234/5?? ... your intended use (2225 being more similar to a 2205 in terms of typical use for sound reinforcement, where 2234/5 sees more use in sound monitoring or 'hifi'). Neither choice is 'wrong'.
Availability of recone kits may also drive you toward one or the other, if you just want to have a pair of working drivers and the usage plan can follow
The biggest issue is going to be what's available so see what you can find and as said above decide how you want to use the driver.

One last question, I'm looking at the pictures, the picture on the left is the JBL 2225H recone kit and on the right is the JBL 2235H. If you look at the Voice coil pictures, one is higher than the other. Does it matter and is there anything special I need to think about when I mount the recone kit
peppes,
BTW, looking at your kits picture.
My all original 2205H woofers appear to have a little more cone ridges than your left 2225H recone. Maybe a couple more. The last ridge on the 2205H cone, towards the frame, seems about 1/2" away from the surround.
This would mean the number of 2205H cone ridges is closer to that of the 2235 kit, though different surrounds.
It might have to do with the 2205H having lower resonance (Fs 30 hz) than the 2225 (Fs 40 hz), the former may require additional cone rigidity due to the potentially lower bass capability, while both have the same Mms.

Do the kits come with adequate instructions for setting the voice coil height?
-seems- like the bottom of the 2235 VC should drop in about 1.9mm lower than the 2225 (.6" vs .75" coil), but I'm no reconer!
I'd want it done right, and I have never built up a recone kit from scratch. Seems a path fraught with peril (or much learning) without the proper tools/jigs/experience.
Official JBL kits came with the spider and VC pre-attached.
Same here, I've never built a recon kit from scratch. I have the old speakers that are complete and I can measure and check them. Instructions are included and there is also YouTube to watch. I check in the instructions, you can read within " " "Insert the plastic shim around the center pole of the magnet. Place the voice coil around the shim and adjust the height (refer to the original coil if necessary). Coil cables must line up with the terminals on the speaker frame. Make sure the voice coil is tight against the center post so it will not move during installation of other parts. If the shim is also thick, you can cut the shim into strips 1" wide and spread them evenly around the coil piece to make sure the voice coil is tight and evenly spaced."I think it will work if I read and check carefully before I change. But if I fail, it will be very expensive for me I need to pay for expensive shipping and customs fees to bring the recon kit to Sweden
Hello peppes
Don't you have a local shop that can install the kit for you for a fee?

yes that might be a good idea but there is no company in my small hometown i have to send them. I like challenges and want to try installing the kit. But it might be an expensive lessonHello peppesDon't you have a local shop that can install the kit for you for a fee?Rob
peppes,
There's nothing wrong to try doing it yourself however its preferable to have some knowledge and/or a written reference you can trust.
Attached are pics of JBL's official recone procedure, this may help reduce the risk of error. I'm posting for you the older of the two versions of the procedure since you are dealing with a pretty old 2205A.
Sorry for the two-part and repeat of some paragraphs but the text is longer than a single page.
Hopefully that guidance will help you succeed. That could be of interest for other folks too...
