Springfield Speaker Pro-Grade Black Rubberized Repair Adhesive Glue (1/2 oz)

The good quality is superb. I had a whole the size of a nickel in my subwoofer. I created a patch and use the glue. It dried quickly six hours. It wasn’t running. It went all nice and thick and when it was finished drying, it was a smooth finish. Very easy to use bottle and a low quality itself has a strong bond and doesn’t have an odor.

Good product. Fixed my speaker

I needed to replace a pair of speaker center cones and this worked very well and has for over the past year with lots of speaker use and no signs of glue degradation.

while listening to my daily driver at a low to medium volume, there was suddenly a rattling quite like the voice coil former was tagging the pole piece. had to finish drive home with no tunes in SoCal, bummer. got home and pulled the offending sub box. i found the pulp type cone had ripped off the foam surround about half way around. this is a ddaudio 1508, 500 watt rms, long throw 8 incher, pretty good at hard bass when you have two like i do. i will be getting a recone for this but i wanted to find out if a repair was feasible. i ordered this adhesive (Pro-Grade Black Rubberized Speaker Repair Adhesive Glue (1/2 oz) - Dries Black, Brand: Springfield Speaker ). while i waited for it to arrive, i slit the rest of the surround off of the cone while preserving the overlap, mirroring how the detachment was already. then i cut the dust cover off of the cone to expose the voice coil and pole piece. it is super important to ensure the voice coil travels exactly parallel to the pole piece. so, i stuck 3x5 cards evenly down the gap until the voice coil/cone was stiff to move. folding the surround back i squirted a layer of glue around the cone matching the old surround lines area. a couple minutes later as the first layer soaked in, i went around again with a thicker layer of glue to be sure i had plenty and not worried about tiny amounts of dribble, it's an out of sight sub after all. then, i pulled the cone up slowly to contact the surround plus a little more up, like an 1/8 inch or less, looking for good contact. the next day i went back and added a glue line over the thin lip of the surround and down to the pulp cone as more adhesion, i also added a lip of glue to the back side of the cone and surround, only missing small areas where the steel basket was in the way. a coupe hours later i pulled the 3x5 card shims out, blew out the voice coil with compressed air and glued the dust cover back on. the next day i dropped that sub back in its box and put it back in the daily driver. the first test was some old ying yang twins, me and my brother album. the suspension is already well broken in so i let that sub have it. and for a few minutes i went into over excursion just to see. i went long and hard enough to smell the voice coil adhesive till i backed it off a bit. the glue was holding perfectly and the sub sounded just like its twin that did not come apart. back to banging, and no odd noises, just like it should be. for the next week at nearly two hours a day commute i beat on those subs with gangsta rap/crunk and similar. 2 500watt ddauio 1508 on a jl audio 1200/1. then i went back to my normal metal/hard rock diet. it's been just over two weeks now and the adhesive sold here is still holding like the day i put it on. visual inspection, everything just like i glued it. i still plan to do a recone on this mfg in 2010 sub just because it's so old, but i'm going to wait a while and enjoy the $12 repair, knowing this is a cheap option for the future. good adhesive!

Used this to refill the surround on a 10-in Polk Momo subwoofer. I've been banging away with the bass for about 2 months now and no problems. I'm giving it four stars because I don't know about the longevity. But so far, so good. I'm a Metalhead so I'm not listening to hip hop. But there is still a lot of bass.
