Boston Acoustics 8 Inch Foam Speaker Repair Kit FSK-8 (Pair)

I have an old pair of Boston Acoustics model A70 speakers, even today a nice sounding, elegant looking pair of transducers. But the foam rings that support the edge of the cones on the woofers had basically crumbled to dust, as these tend to do after a few decades.I was pleased to find this inexpensive kit by Simply Speakers, and put the kit to use in accordance with the well written and illustrated manual that comes in the kit, and also with the well done video on YouTube that they have put up.The kit includes one pair (2) of replacement foam rings, one tube of special glue, and the small instruction manual. The kit does NOT replace the 'gasket' on the front of the speaker frame, but if my own A70s are any indication, those gaskets must be made of something different from the rings, because they were still in excellent shape (and anyway, these woofers mount to the A70 cabinets in such a way that the gaskets are not used, and just serve to improve the appearance of the speakers).The procedure is simple and well explained, but I do encourage you to also watch the video; they cover exactly the same steps and points, but seeing it actually done helps boost your confidence level in ways that the printed manual cannot.The only tools you need are isopropyl alcohol (or the watered-down version known as 'rubbing alcohol), a flat-edged utility knife and a few old rags (old T-shirts would be great for this), but personally I used "Tech Wipes", a tough, lint-free, absorbent paper towel used for cleaning of precision equipment. Of course, depending on your speakers, you probably also need one or two screwdrivers to remove the woofers from the speaker cabinets.The basic steps are as follows:1) remove screws or other hardware as required to remove the woofers from the cabinets2) unplug the wires from the woofers, and use the knife to pry the gasket away from the frame (save for later)3) use fingers to remove all loose and crumbling foam from between the edges of the woofer cones and the frames4) wet a rag with alcohol and saturate the remaining foam and old adhesive on the woofer frames (which softens the foam and adhesive), and use the knife to scrape away the resulting goo5) wet the rag with more alcohol and carefully soak the remaining foam and old adhesive on the rim of the cones, then carefully use the knife edge like a squeegee (NOT with a cutting motion) to scrape away the goo from the cone edges6) wait for the alcohol to evaporate and any remaining adhesive residue to dry7) orient the woofers so the cones are facing up, and so their magnets are resting on a piece of paper towel, old rag, etc; so you can easily rotate them as you work, without the magnets scratching whatever they rest on8) with the foam rings upside down, apply a bead of the special glue to the underside of their inner edges, smear it flat with your finger, flip the foam rings right side up and set the glued edges down on the edges of the cones (of course you do this one woofer at a time), gently pressing the foam against the cone, making small adjustments to position concentric with the cones, until the glue gets tacky enough to remain in place without your help....this takes less than five minutes. Note that the remaining old adhesive should have left enough of a mark on the cones to act as a guide for positioning the new foam rings9) wait one hours for the glue to set up fully10) lift a bit of the outer edge of the foam ring (which rests on the metal frame) and fold it over enough to apply a bead of glue, moving your hand along the edge and turning the woofer until the bead goes all the way around.11) reach under the woofer and use finger tips to lift the cone upwards, this will separate the newly glued foam edge away from the frame momentarily, then lower fingers so that the woofer's 'spider' pulls the cone back down until the foam ring sets down on the frame12) press down on the middle of the woofer next to the dome, then lift partially back up, to check for any sign that the voice coil is rubbing (you can hear it doing so), which would indicate that the cone is not properly centered13) if the cone moves up and down without causing the voice coil to rub, then press the glued foam down firmly onto the rim, and work your way around the edge, turning the woofer as you do....the glue sets up over a few minutes, so initially it seems as if the glue will NEVER start to grab, but then it finally does14) wait one hour for the glue to set14) use some remaining glue to reattach the gasket if so desired (wait another hour for the glue to set)15 reattach the wires and reinstall the woofers in the cabinetsMy woofers came out looking and sounding great. The process was easy, but it helps if you take your time and do it carefully.

My friend gave me an old pair of Bose 301 speakers, telling me that the foam on the bass speakers was worn out, but that I could buy a kit to fix this. I bought the Simply Speakers FSK-8 kit and it worked great. The speakers now sound wonderful. Instructions were good. I suggest watching the video. If you are not real steady when applying the glue to the foam, then I suggest doing it on top of a newspaper instead of on the speaker as shown in the video. I got some glue on the foam and speaker paper. When I glued the foam to the base on the second speaker it was off center. I could not slide part of it into the correct position, so I pulled the entire foam up and re-positioned it. That did the trick.

I have a pair of Boston HD8 speakers that I have connected up to my living room AV system. Recently I had been hearing crackling coming from the speakers. I initially thought I had accidentally blown them by playing my music too loud. But, when I popped off the front covers I could see the foam edge was badly deteriorated and falling off. Not knowing anything about the construction of speakers I assumed I had to buy new ones, but after a little research I was amazed to find the Simply Speakers repair kit on Amazon. Last night, I watched their repair video on YouTube, unscrewed the speakers and disconnected them from the speaker housing. I found some rubbing alcohol to help clean the speaker cones and mounting area from the old foam and glue residue (this is an important step so don't skip it if you want the new foam to stick properly). Also, as they show in the video a small scraper like a craft knife will be very useful to scrape away the remaining bits of foam and glue residue. The new foam edge is a little larger than the available space so you might want to shave off a little to fit properly but I doubt this makes much difference in reality. The glue is very sticky so keep a cloth handy in case you get some on your fingers. Wait about an hour between the two glueing steps (inner rim stick to the cone, and the outer rim to the speaker frame) and reconnect and screw the speakers back in the housing. I fired up the AV receiver and the speakers work better than I even remember! Great repair - highly recommend this kit.

A little pricey for what you get, but cheaper than a new woofer. Only 4 stars because I had to trim the outer diameter of the foam about 1/8" around the circumference for best fit for Boston Acoustics 380 in-wall speaker (8" woofer); expected a perfect fit without modification. Watching their videos, repair is easy to do and works fine.

One of my 30 year old in wall Boston Acoustic speakers started making a rattling noise and when I removed the grill I discovered the foam around the mid-range had crumbled. Looked at all the other ones and found they were also in bad shape. Ordered and installed this product and they sound fantastic. Installation was straightforward. Hardest part was being on a ladder removing and installing the speaker. Tried removing the entire unit rather than just the speaker but that didn’t help. Once the speaker was out it was just scrape off the old foam and glue the new on. Support was VERY responsive. Only suggestion is that the glue be ordered separately. A tube comes with each repair kit which includes 2 pieces of foam. I used less than 1/4 of a single tube for a bunch of speakers.

These are nice and easy to install. A bit pricey though-

The right part. Correct fit. Speaker now works good. Install is easy but time consuming (removing and cleaning off old foam). Overpriced for what you get; 2 pieces of foam and glue.
