Servo Feedback: Some advanced subwoofers may use a feedback signal from a device mounted on the speaker’s cone. The servo control unit compares the subwoofer’s output to the input signal and attempts to compensate for the driver’s output errors in order to smooth out distortion level. Unfortunately, this feedback circuit, no matter how quickly it works, cannot make the correction until after the error has occurred. As a result, the correction is always arriving at the woofer output with the next signal. Therefore, the correction is made on the wrong signal and it may compress the woofer transient response and remove its impact.
Down Firing: This type of subwoofer has the woofer installed in the bottom so that it fires toward the floor. Down-Firing subwoofers look like a piece of furniture (do not need a grill) and may be more efficient. It is important that these types of subwoofers are not placed in a corner too close to the walls as they may sound boom!
