Ok, here a few very rough pictures.  Keep in mind that these aren't fully setup, but rather just plopped down so I could get an idea of their performance.

Are these only to be mounted vertically?

Thanks guys! It's great to get such rapid feedback from not one but two happy customers!

Also, Max:

> Are these only to be mounted vertically? <

Yes. The arrangement of the vanes diffuses sound to the sides which is the most useful way to scatter sound in a room with a "normal" ceiling height. If the diffusors were mounted sideways the sound would be sent up and down, toward the ceiling and the floor. That works too! But not as well as sideways because usually there's more distance before the reflected sound hits a side wall.

We have considered making models meant to be placed sideways, but a thin strip only two feet high isn't really large enough for a diffusor to have much effect.

I noticed in this thread a reference to correct speaker wiring.  How do you know it is correct??????  In our experience, if you hook up everything "by the book" the absolute polarity will many times be incorrect.  This is due to the fact that believe it or not, all manufacturers are not on the same page when it comes to absolute polarity.  We learned this in the pro field doing studio installations.  If you put a positive voltage on a JBL monitor for example, the woofer moved backwards!  This led us to invest in a German made unit that tests for absolute polarity in both the acoustic and electrical realms.  The clicker could be placed on a microphone, for example, and the pickup on the monitor out (line level) of the console.  We could of course complete the monitor chain, bringing the eq, amp, and speakers into the equation by placing the pickup at the cone of the monitor speaker.  It is a several day job to go through all the microphones, cables, outboard equipment, console outputs and monitor chains to correct for absolute polarity.  We would change the wiring inside the microphone for example, swap pin two and three on offending balanced units, and change the amp to speaker interface at the amplifier end.  This was of course after we were certain all the speakers were correct.  They would be corrected if necessary by changing their internal wiring.  Many people have home studios today, and often they wonder why they do not get a mix to cause shivers like Steely Dan.  The answer is, of course, the devil is in the details.  Any audio system needs the same care in installation to assure absolute polarity.  If your system has not, the odds are almost 50/50 that you do not, even though you have the red hooked to the red and the black hooked to the black.
