JBL Speaker (4410) repair question

Often times the rubber cork or synthetic gasket will "glue" itself to the baffle over time.

Some DIY speaker builders actually glue the speakers to make sure the seal is secure... I doubt JBL did that.

So what I am saying is that, in my experience, you often need to "yank" the speaker loose with a short sharp tug. Now, if for some reason it is glued... then my method isn't so good.

If it were me, in the absence of info... I'd give it a good hard yank.

The best advice is of course to contact JBL... I am sure they will be very happy to help you.

all the best,

I know this is old but if you're still around did  you ever figure out the issue? I'm about to embark on the same  project and am researching what to potential issues/problems.

I just re built my old Tanoy 6.5 using parts from these guy's. They sound like brand new again for less than $50. They still suck when put beside my Yamaha NMS10's but I'll use them for Home stereo. 

I have all JBL speakers, and yes they will stick to the cabinet and need to be loosened. Do not think that is bad, usually the surround will not break either (and if the surround did break they can put on a new one). I have 34 year old Professional speakers (not used so much anymore - no room -big speakers cabs) but they still work fine and new speakers may be different, but really they are not better (except maybe more punch in the low end which I do not need using a smaller speaker - mine are bigger). I have 8" speakers and tweets like the new ones in other cabinets and to me the new ones are newer and should be better but also to me, they do not sound that much different. I read where bass guitar players are still using those 15" speakers like my Pro speakers still to this day like the 140's, I think mine are K140's but have to look it up to play bass guitar through it but I use mine for stereo speakers. Just the white coned speakers had a little better transenient response. In fact some people would prefer the old cone paper speakers over newer ones and like I said still do for playing an instrument through those speakers even back to the D130 series way before mine. I had my 10" speakers recone a long time ago now, and they upgraded those to the next version at the time (so they handle more power then they did before, but to me it did not change the sound of them). Might want to remember how they really do sound and used to sound. I still use mine and probably will have to take them to the land management trash place (landfill) before they are really dead (I don't really see selling them).
 
Something to think about.
My JBL's are all passive speakers though and as good as the amp that is connecting those up.
 
Just keep working with the speaker to loosen it up. After years of heat and environment, things get sticky well kind of pressed to stick to the different surfaces.
 
 (and bullet ring radiators with those 10" and 15" speakers for the tweets. Of course the K145 would have been better, but heavy is why they probably are not budging easily from the cabinet.)(and still to this day it is area cone of the speakers that determine bass response and 18" speakers are even better for real low end response).

But who wants to move 'em?????
(crossovers not withstanding on those speakers either).
Pretty pictures of my speakers.

Ya, I done with this post.
Should I include the crossover picture?
Okay, I am done.
