Audio Amplifier Signal Splitter

Have you guys heard of this, claim you can link a bunch of speakers and maintain the ohm load. if you have, maybe point me in the direction of some schematics? Here is the only commercial example i can find.

Their example of driving 4 speakers of 8 ohms each, seems like they just have a series parallel circuit wired in the box. You can do that without buying that box.
