The foam replacements worked very good for my very old Boston Acoustics Sub Sat 6 main speakers. The replacement foam was a little to large but i was able to trim them carefully. I emailed Simply Speakers with questions about the process and they responded very quickly to all my questions. I felt like they were there to help with any question or issue I came across. They have been working very well and if my other speakers Boston Acoustics speakers start to fail I will order additional kits from them. Their online videos helped a lot.
