Mr
The surrounds fit perfectly; the glue held them in place, and a month later, all is very well. I've cranked up the volume and bass; all is well. My cX 100's are now good as new! (and that is very good indeed!)

Super quick delivery. Easy to follow instructions included. This was my first attempt at repairing speakers. It was easy. My Bang & Olufsen sound like they did when they were new - GREAT!

Mr.
Speaker foams were promptly shipped. I had to customize by cutting the foams, and tech support was extremely helpful and responded promptly to my inquiry.

mr
since this kit was for a specific speaker I would expect it to fit properly. the foam ring was to big for the speakers though I was able to find a solution on your web site of cutting the ring to fit. parts where delivered on time and UNDAMAGED the glue tube opening was to large for this speaker size and put down to wide a bead of adhesive but in the end all worked out ok. my unusable speakers are sounding great now thank you !!!!

I used the repair kit to replace the crumbling surrounds on an old pair of Beovox cx100 speakers. Overall the kit worked fine but it did require me to create some tools to get good results. My only complaint about the foam surrounds is the inside diameter could have been smaller by at least an 1/8 of an inch to give a bit more gluing surface to the outside edge of the speaker cone. As for getting a good glue seal I used short sections of acrylic tubing, one for the inside and one for the outside edge, to weight down the foam while it dried. I noticed that the glue when first applied to the foam will make it deform and curl, making it tricky to adhere it evenly with just the fingers or a burnishing tool. It is easy to shift the position of the surround with all the rubbing. The outside edge is easier to glue down because it is being adhered to a flat surface. I used an acrylic tube with a straight cut to hold it down. But the inside edge is being glued to a cone that is angled down. So to get a even flat seal I made a bevel cut at the end of an acrylic tube to match the angle of the cone. I got successful results despite having to redo one misaligned speaker. It helps to have some dexterity and delicate touch. I would have paid a little extra for some plastic rings to aid in the glueing. Thanks, Evan
