Recent refoam projects:

Bang & Olufsen Beovox S55. It's a streightforward repair job, those Beovox 8" woofers. You just glue the ring to the front of the speaker cone. The same proces can be used for many, many other Bang and Olufsen speaker units.
Philips Digital World series FB561. A special woofer. Not only is the ring glued to the backside of the cone, the ring is also 'inverted'. We chose to repair this unit using a special 8" foam ring. This unit can also be found in Philips' FB563 and FB565, but more speakers use units like these, for instance: FB770, FB790 etc.

Please note we can provide you with many rings. If you want to refoam, please contact us.
