Need help...A different refoam question.

I have a pair of Infinity 652i car speakers with a problem. The glue used to join the RUBBER surround to the POLYPROPYLENE cone has become brittle, and the surround is separated all the way around from the cone.

I am wondering if the glue I have left over from a recent surround job will work on these materials. This glue came in a kit, but I used it on foam surrounds, and paper cones.

Thank you.

rubber cement!
or shoegoo or something similar.

dont use elmers anything, or aleenes tacky glue because they wont stick to the cone or surround well enough.
 
Thanks guys...Anyone know where I can get Seal All?


BTW... What is the use of using rubber surrounds and polypropylene cones if you are going to use cheap glue? What's up with that Infinity? These are only 6 years old.

could be heat, sunlight, water, could even be they were kept in a place with some strange chemicals or solvants and it ate away the glue, it could also just be that they were made wrong..
hows the matching speaker doing??

These were bought new (Crutchfield) and installed in the doors of a Toyota Tundra. One day I started to hear a rattle, but procrastinated on looking at the speakers since it would take time to get to them. I actually bought 4 since the rear doors use 6.5" speakers as well. I suspect that they will all go at some point.

I bought them because I thought Infinity were quality speakers, and these have pivoting tweeters which is important in speakers that are mounted low.

The original glue is yellowish brown, and now hard and brittle. :scratch2: The glue mentioned in the last post (orange county) is also yellowish brown, and it stated that it is good for FOAM to POLYPROPYLENE ...my surrounds are RUBBER.

I just want to make sure I get the right stuff, since it is a PITA to keep having to get to them. The back doors are very easy and I can do them in 10 minutes, the driver door with all the electronic harnesses takes much longer.

Here's a purpose specific glue for poly cones and foam or rubber surrounds that should do the job from Orange County Speaker Repair. For the price, peace of mind is cheap!

I wouldn't use that glue. I got it with some surrounds (they were foam though) and it reacted in a very bad way with them. It was a real pita to get all the glue back off the cone after the failed attempt. The glue may work but I would test a small area first to see if it damages the cone or surround.

Supposedly regular surround glue isn't good enough and this was for a pair of Pioneer DSS-9's that have the polymer graphite cone. I got another set of surrounds and used the Aleene's (sp) Tacky glue. I don't know why you wouldn't think this wouldn't work. It's a craft glue made for all kinds of materials. I've been using these speakers in my main system for the last couple of years without any problems.
 
well i have found with aleenes tacky glue that once it is completely dry it can be chipped off a smooth hard surface easily, same with elmers glue..
imo you want something that is more flexable than that..
i think i would use silicone.
 
It really depends how you prepare the surface. Silicone can be a good adhesive but it too can be easily pealed off if not prepared correctly.
 
Glad you posted on your experience with the poly cones, Denny, I have a pair of Infinity's that need resurround and was wondering about adhesive. I've had good luck with Aleene's on everything else so I'll use it on these.

Elmers will not work. :no: I knew better, but tried it anyway. This was before I got glue with my Cerwin Vega surrounds.

Again..I am looking for glue to join Rubber surrounds to Polypropylene cones. These surrounds attach UNDER the cone which makes it a tad harder.

Lance,

The Pioneer's I used the Aleene's glue on was not poly but a hard graphite cone. Now that I think of it I have used it on a pair of 8" Yamaha's I refoamed for my brother that had poly cones.

I always clean the surface with MEK unless it is a paper cone. This will remove any contaminants or oils that might cause the glue not to stick. Even oil from your fingers can cause problems. Something I think a lot of people overlook.
