Active Subwoofers

Active or self powered subwoofers need a signal and a mains power to recreate sub bass frequencies typically between 20 Hz up to 150 Hz. The signal feed can be full range as there is a variable crossover on the power module to set the frequency cut off point. This allows the user to blend the subwoofer with the remaining mid and high range transducers. Whilst bass is not directional the position of any subwoofer has a great impact on a subwoofer's performance and sub bass capability.
