How to remove B&W 800 N midrange??
I am pretty sure the driver is blown and would like to remove it to test/replace. It looks like the midrange driver is held in by a threaded rod that goes through to the rear of the enclosure. Does anyone know for sure? I am the second owner, so there is no warrantee to be concerned with. Thanks.
