Acoustat, 121-2a can they be cut down

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.

Some old Acoustat freaks will think you are criminally insane just to think to bring them down. You will loose some bass impact by reducing the number of panels and curiously, increase the load on your amp. In any event, if you can, keep the same number of panels.

I've done the contrary, had Model 3s (3 panel wide)and transformed them into 2+2. Celestial improvement on imaging although a diminution of the WAF factor.

You guys are bringing back some Acoustat memories. I had the 1+1's, 2+2's, and Monitor 3's. Basically, the more narrow the panel, the better it will image. That said, using more panels gives you more impact and efficiency.

The 2+2's and Monitor 3's were my favorites and I could live happily with either model. The 2+2's may have imaged slightly better, but the 3's had a bit more midbass impact.

Fire_bottle's idea of cutting the frames so that 2 panels would stand about 5 feet tall (holding the panels 12" off the floor) seems like a good one.

The Monitor 4's had the worst imaging of the lot and you need the right room for those as they are very wide and bass heavy.

Since the 2+2's generally sell faster and for more money than the shorter side by side configurations, you might post them for trade here and ask for paid shipping.

Agreed with Samujohn, you may want to just find the model that fits your room best and sell off the 2+2s, especially if you can do both locally.

Plato, in my experience the Monitor 4s can actually sound downright magical in the right room. I've displaced Model 3s in fairly narrow rooms twice now. With Acoustats it's always a matter of just setting them up and seeing what happens... which is why I tend to keep a stock of various models handy.

Fortunately for me I have low ceilings so it's down to three models - the 2, 3, and 4. Right now the Monitor 4s are winning out to my surprise!
