After using the Greenback cabinet for the Plexi 'Warm' Pack - I wanted to have a Greenback cabinet myself.
Unfortunately are Celestion Greenbacks only 25Watt's ... and my Marshall Cabinet is a 2x12" (1936Vintage).
But since a few month are the new Celestion 'Creamback' speakers available - same sound as the Greenbacks - but 65 Watt's - great!.
Just replaced my two Vintage 30's with Creambacks - love this speaker very much.
