The most common problem with speakers are rotted, torn or damaged surrounds. The surround is the outer suspension part of the cone. Constant vibration, time and the environment cause foam and rubber surrounds to degrade. Cloth and paper surrounds can become brittle. This causes distortion and poor performance.
Luckily, our easy to install repair kits will make your old speakers sound just like new!
New-Edge-It® speaker repair kits. America's # 1 brand since 1992.
See Product Description, Title or the "Fits Models" tab to see speakers listed for this repair kit.

Outer diameter: 3.875" (98mm), Roll outer diameter: 3.5" (89mm), Cone diameter: 2.875" (73mm), Inner diameter: 2.5" (64mm)

Pretty good
My first attempt was a bit messy, but speaker 2 was better. Note that for Boston satellite (Sub-Sat 6) you need to pull off the metal grille by hooking a paper clip or similar. Warning for other UK customers: customs will slap on £13 import duty which needs to be paid before delivery.

recently purchased the repair kit (FSK-4)for my Boston Acoustics Sat 6 speakers. repair kit was delivered in a timely fashion with all parts included, including easy to follow step by step instructions. the product was of fine quality well worth the money spent. The customer service rep was helpful and very professional. The finished product was a fine sounding speaker and you could not tell it was done by an average joe .... sounded like it was repaired by a professional. I will truly order more speaker repair kits from this company for I do have other speakers that are in need of repair. And now that I know how easy it is to repair speakers I shall do so with confidence regards... Bill

Mr
The items were great, speedy delivery and good customer service. I had a bit of hard time putting them on as the speakers are small and I have big hands. So happy to my Boston SubSat 6s back in working order. Thank you so much guys. Will recommend you and use you again, if needed.

Just as promised. I followed the YouTube video. These were smaller speakers than demonstrated, which made handling the speakers a little more challenging than the video showed. It worked out great. I wish I had not thrown out all of the previous speakers. Thanks!

Worked perfectly for my Boston Acoustics SubStat rear speakers. This is my second foam speaker repair kit. When you follow the instructions it works perfectly replacing the foam edge and you've just extended the life of your speakers inexpensively.

Works as advertised!
I have an old pair of Boston Subsat 6s from the early 90s. In the early 2000s I had a woofer go and at the time was able to get a replacement woofer from Boston for about $75. Fast forward 10 years and the second had the woofer foam dissentegrate and I left it unused (going to a mono setup) thinking I would get around to finding spare parts). I came across this site and watched the videos so I knew was I was getting into and removed/cleaned up my woofer and then order this. It took no time at all to install and now the full setup is back up and running (currently using as a Zone 2) again all for a 1/3rd of the cost of replacing the woofer 20 years ago, not considering inflation)!

Q:
I need a phone kit for Boston Acoustics SubSat6 Series II speakers. They are about 3 7/8 in outside old foam measurement and the paper cone is a full 3 inches not the 2 7/8 measurement for your 4" version. Do you think this FSK-4 kit will work with my SubSat6 II speakers? Regards, Keith
Asked by:

A:
Yes, this kit works great on the Sub/Sat 6 (satellites). We also sell the subwoofer kit if you need it.

Q:
Hi. I need to order these for my Boston Subsat6 satellite speaker. However, I can't see how to disassemble the speaker cabinet! Does the metal grill just pull off? Thanks.
Asked by:
Steve Jones
- 5/15/2017
A:
Yes, the metal grill must be carefully pried out (we use a putty knife). Then you can easily access the driver for service and repair.
