Basic Study - Part 2 - Compression Driver

The compression driver removed from the horn assembly. The tissues are "improvised" method to stop contamination to the voice coil magnet's gap. There is supposed to be a metal net on the horn. However this horn is made by Image Dynamics, further more bought 2nd hand, therefore did not come with a protection net :(
