Acoustat, 121-2a can they be cut down

I believe the panels themselves are 8 or 9 inches wide by 48 inches long... If you remove the socks, you will see exactly how they are made. Obviously you can't cut the panel and leave it functional. Some have wood bases that add a couple of feet and other models use stacked panels. The model number you list is for the electronic interface, so I have no clue which model speaker you have or whether or not it could be made shorter.

The Acoustat that I have is 7'10" tall and is about 20" wide....If I remove the base can the sock be pulled off from the bottom or does it come down from the top....Will

You have a pair of 2+2's, which are (2) panels side-by-side and another set on top of those. You could take off the top panels and would have a pair of Model 2's. The link below will answer most if not all of your questions.
