Frequency Ratings Explained
OK, you see the speaker table above? You see how we’ve listed the lowest and highest frequencies a particular system can put out? This is important for a couple of reasons. The first is that it gives you an idea of just how wide the range of of sound your speakers can deliver. Humans can’t really hear anything above 17kHz (kilohertz) so don’t be swayed by a system that can go up to 50kHz, but it’s good to know nonetheless.
One of the things you may have to do at some point is set the subwoofer crossover. Simply put, this is the point in the bass playback at which the subwoofer takes over, meaning that the additional surround speakers don’t have to put out low bass notes. That means more power for the things they are good at. Setting this is absolutely simple. Usually, it’s done via your receiver’s on-screen menu. All you need to do is look at your subwoofer specs, and see the highest frequency it can go. If it’s at, for example, 250Hz, that’s where you set the crossover point. You’ll be amazed at just how much of a difference this can make to your system.
