These are great speakers that were at the end of their life, now they sound like new without the cost of new speakers.

Repaired a pair of Boston HD7's with this kit. Worked as expected. Takes a little time to get all the old surround off, but other than that, wasn't bad. Their tuning video was worth watching to validate everything was good before the adhesive sets.

Used this kit on my Boston Acoustics HD-7s and the resurrection from the dead was done. They sound great again. It's really easy to do this with these speakers. You don't even have to remove them from the cabinets. Nothing too special when it comes to packaging but you get what you pay for and it works. Would done again.

These fit the HD7 speaker exactly in terms of diameter so no trimming needed. The hardest part was removing the old foam and some of the residue glue from the frame. The HD7 cone is plastic so not as sensitive as a paper cone.

This product worked exactly as advertised--and resuscitated my 30-yr old BA speakers. It's simple to install the foam rings, but you must allow time for the glue to cure properly. So plan for some down time between steps. I can't stress enough how important it is to read the well-written instructions carefully (unless you're a seasoned speaker builder)!
