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!

The foam replacement for the Boston Acoustic speakers included the special cement. I was able to repair 2 speakers whose woofers had lost their foam mounting over time. The 25.00 price seems a little high for small pieces of foam and cement but it did allow me to resurrect speakers that would cost 300.00 to buy new.

HD-5 repair

Thank you for the quick delivery of my order. The 5.25 FSK was an easy and perfect fit-up for my old HD-5s. They sound great!

Perfect fix for my old HD5's

I have had a pair of HD5's for quite some time and I absolutlely love them, but the foam blew out from age a few weeks ago, and while researching a new pair of speakers, I came across this foam kit to fix them up new. The installation was pretty easy, aside from a little glue gone wild, and after letting them set for a few days they are good as new and still sound great.

These edge repair kits are great. I have not only used this kit, but a couple of others as well. The kits allowed be to bring around $2000 worth of speakers back to life for around $75.

Q: Repair is for Boston Acoustics HD7 speakers. Cone is 5.25 edge to edge (inside edge of foam line) Is this 5.25 Foam Repair the correct size? I assume since you do not have a 7" repair kit - speakers are 7" to outside of metal ring. Thanks

Asked by: Charles - 6/9/2016

A: For your Boston Acoustics HD7 model, we sell the exact repair kit. Please order foam replacement kit part # FSK-7HD7

Q: Sorry for 2nd question, similar subject (THANKS for 1st ?, your answer was very helpful). What repair kit should I order to replace my Boston Acoustics Model 350: the FSK-5.25 Foam Kit OR the RSK-5.25 Rubber Kit? My current BA Model 350's have a Foam edge, so I assume I order the Foam FSK-5.25 Kit ---- which I assume will fit my BA Model 350's even though this model number is not listed in the 'product name' like the rubber kit. Again, THANKS for your answers.

Asked by: Gary - 2/10/2017

A: Yes. Either kit will work. They are the same dimensions. Rubber lasts longer, but is also heavier so it will reduce efficiency a bit. That is normally not an issue.

Q: How is this kit different from FSK-528 and which one should I use for Boston Acoustic HD5 fix?

Asked by: Michael from Texas - 7/27/2017

A: The FSK-5.25 is not a "filled fillet" surround, and as such, the inner lip to roll of the foam is not filled in. Either kit will work, but the FSK-528 is the technically correct kit for the Boston HD5.

Q: Is this the recommended kit for BA C 700 or is a rubber kit better?

Asked by: doug - 9/1/2017

A: The original is foam, but the rubber kit part # RSK-5.25 will also work. Rubber is longer lasting, but a bit heavier so it will reduce bass efficiency a bit.
