Not sure if members of this forum are aware of the following:

A commercial version of a mid-side speaker system has been offered for quite some time.  I bought two Space Station Mk II powered "single point stereo" speakers that were designed by Aspen Pittman when he owned and operated Groove Tubes.  I use them regularly when playing small to medium sized gigs (guitar, vocals, keyboards).  The 300 degree sound field from these things is amazing!  Not really true stereo, however, they reproduce the stereo effects used in keyboards (like that of a Hammond Leslie cabinet) remarkably well.  They provide an output for a subwoofer then when used rolls off everything below 100Hz from the internal speakers since the sub will then be handling that.  The internal speakers are about 10dB down at about 60Hz.  The "stereo" effect projected by these speakers is even anywhere in a room - a very interesting phenomena that is very pleasing compared to mono.  Conventional stereo does not work well in for live sound PA system applications.

Info on the Space Station MkII (no longer produced) can be found here:

Hi. This is my first post here. I found this place while searching for information on Mid Side Speaker arrays.

I was recently ask to modify one of my MS Mid Side Matrix boards for a guitarist who had used the Centerpoint Space Station but felt it under-powered and wanted to try it with larger amps and different speaker arrangements.

In the process of adapting an existing mastering width circuit I had a chance to listen to a three speaker Mid Side Array and was blown away by the huge ambient image. I was impressed enough to want to build another one for myself for casual listening.

I've posted my thoughts on proaudiodesignforum.com along with schematics for the encoder: http://www.proaudiodesignforum.com/forum/php/viewtopic.php?f=6&t=742

This is the Mid Side board and Width control. Only half the board is used.



The inputs are Left and Right; the outputs Mid and Side. The Width Control varies Side from 0 to 100% as Mid is varied from 100% to 0%.  Four of the ICs provide balanced I/O. The heart of the MS encoder circuit are two THAT1240 and a dual op amp such as the LM49860, NE5523 or NJM2114.

The positioning of speaker at the mid side is not a bad idea.

Thanks everyone. I'm really anxious to get the speaker array set back up and have some of my geek neighbors come over and listen to it.
