Tizman Posted November 6, 2021 Share Posted November 6, 2021 Hi All. I picked up this woofer last week and was hoping someone could help me identify it. It came with a couple of drivers that the seller identified as being Klipsch in origin. The lot included a K-48-KT. This driver has a cast frame and looks most like a K-45. The ribbed spokes on the basket are the same, and the rear vent and cone look the same. The big difference is the extra magnet attached to the back. Any insight would be much appreciated.

What impact to parameters is normally expected when adding a magnet like this? My intended use is in a large horn subwoofer. Quote Link to comment Share on other sites More sharing options...
Tizman Posted November 6, 2021 Author Share Posted November 6, 2021 For the purposes of speaker design, are the effects on the driver parameters significant enough to keep me from using the normal K-48 parameters? Quote Link to comment Share on other sites More sharing options...

My intended use is in a large horn subwoofer. It's called a ceramic ring magnet , it comes in various weights and sizes , this is added to increase the driving force of the woofer and a more punchier bass than stock Quote Link to comment Share on other sites More sharing options...
