Subwoofers![]() A subwoofer is a type of loudspeaker dedicated to the reproduction of bass frequencies, typically from about 20 Hz to perhaps 200 Hz in cone speakers, and in the case of a rotary woofer, all the way down to below 1 Hz. It is difficult for small loudspeakers in typical enclosures to reproduce frequencies below about 40-50 Hz, especially at high output levels (say, above 100 dB) as their cones will move farther than any practical driver construction can provide for , and so it is often advantageous to use a loudspeaker specifically designed for handling low frequencies at high power levels.
