Up for sale here is this new GRS 5SBM 5" sealed back midrange.  This came from a closed repair shop.  It is tested and plays well and works great.  Please make sure this is the right driver for you. 

Please see my pictures for details.

US shipping and handling is $10.  If you have any questions, please ask. 

I have more speaker parts and other vintage electronics listed--feel free to take a look!
