Beautiful, Ruben. How are these attached to existing speakers?
Thank you, Sir!

They attach via threaded inserts and 1/4" x 2 1/2" screws.
Here are the steps:
(1) Flip the enclosures upside down.
(2) Remove the original bases.
(3) Transfer the hole pattern from the new bases onto the underside of the enclosure.
(4) Drill for the threaded inserts and screw them in.
(5) Attach the new bases.
(6) Flip 'em back over and admire the new look!

Ruben
