Bass Management
One of the least flashy, but most revolutionary features of the Revolution 7.1 is its advanced theater-grade bass management. First, we should discuss what bass man- agement is and why it’s important. Then we can talk about why Revolution’s im- plementation is so advanced.
The most common home theater or surround sound speaker sets are made up of small speakers (satellites) that surround the listener. These speakers are generally not full-range, tower-type, speakers capable of reproducing everything from the lowest bass to the highest highs. The key to using type of speaker configuration is to route bass that would normally go to these satellite speakers to a subwoofer instead. This works because bass is perceived as “non-directional,” meaning that you can place a subwoofer almost anywhere in the room and have it represent audio coming from any speaker. The simplest method of implementing bass management is to set a single crossover frequency for all your satellite speakers, below which all sound goes to the subwoofer.
