[QUOTE="Ivan Beaver, post: 141413, member: 30"] Re: Infocomm??? Actually it is NOT the same. In the other "products" that you describe, each transducer is still acting as a "omni" source-producing interference to the other devices. It is through this destructive interference that they get their pattern. The SBH is using constructive gain to get the pattern. Yes the "apparent source" is further behind, but how it is done is completely different. Here is an easy test to see whether or not there is much self interference in a cabinet. Take a pair of them and set them up in stereo. Place another speaker of any type in the middle and do NOT hook it up. Now play a good stereo signal (preferably with vocals) and see how good the "phantom center channel" is. With well behaved sources, you will SWEAR there is a center channel. You have to walk up to the speaker to see that it is actually NOT on. With other systems you can kinda get a "center feel", but it does not appear as if there is coming out of the center speaker. This works for other types of systems as well. [/QUOTE]
