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.

Unscrew the long rod from the back, hold the driver from the front while doing so as it will eventually "fall out".

Use a very large screw driver or something as wide as the slot, or it will leave mark on the "screw".

It's not rocket science, I have done it on 802N.
Don't have a direct answer, but I had to replace a tweeter (on a much cheaper DM series spkr). When I called B&Ws US importer/service ctr in MA, they were very helpful with instructions on how to do the replacement. In fact, I also ordered a gear for my Rotel CD drawer assembly and they were instructive for that fix as well. Great service for a $30 parts order.
Arcoleo and semi.....congratulations, you know more about this than my local B&W dealer. He is looking into borrowing the 700.00 tool from B&W. What a pain! Thanks to all for your help.
