The Final 0.3 hybrid electrostatic loudspeaker was an excellent speaker in its day.

Some of these loudspeakers are now requiring attention to the electrostatic panel due to the aging effects of airborne pollutants. This has caused the panel to become less sensitive that it should be causing a mis-match between bass and treble sections.

All is not lost! The panels can be re-built given our repair kit and a little labour. Our repair kit provides materials to allow you to replace the diaphragm with a thinner material which will give superior transient response.


Cost     AUD $180.00 

Due to postage restrictions we cannot supply all materials required for this rebuild, however, we can advise suitable alternatives that should be able to be sourced locally.
