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.

Just post your questions there and search the archives.

Here's another about tweaks:

To add to Mofimadness' post, you can easily transform these into a pair of Model two's as you suggest by removing the panels and cutting the frame down. I would suggest two things:

1) Cut the frames to about 60" tall and re-mount two panels in each frame near the top. You want the panels to be about 12" off the floor for most rooms. Of course it would be easy to experiment and well worth it.

2) Inside the interface, you'll see a terminal strip with a wire clip. This is the input the the bass transformer. You need to move the wire clip the the correct transformer tap for a two-panel speaker. You want the Red wire. There are three - Yellow is for 4-panel speakers (Model 4 or 2+2), Orange is for 3-panel speakers (Model 3), and Red is for 2-panel speakers (Model 2 or 1+1).

Also if you can do some more frame construction you may want to consider putting together a set of threes (three panels side-by-side) and using the orange tap. IMO, it is better to go wider with Acoustats before going taller - I very much prefer the sound of threes to 2+2s. Better yet, make some fours if your room is wide enough!

Good luck with your project.
