Subwoofer amplifiers provide your speakers with all the power they need to shake the earth. A subwoofer reproduces very deep, low-frequency bass sounds, from 20 to 200 hertz. They are usually 8 to 12 inches in diameter. A tweeter produces high-pitched noises and are usually about 2 inches in diameter. Both a tweeter and a subwoofer can be hooked up to the same amp. However, the sound quality will be lessened unless a passive crossover is used. A passive crossover sends high-pitched sounds to the tweeter and low-pitched sounds to the subwoofer, enhancing the clarity of music. Writer Bio
