Great bass is still an integral part of any music and theater system. From the rumblings of a distant thunderstorm to the in-your-face percussive attack of a kick drum, deep, resonant bass is responsible for much of the emotional impact of any audio system. Since the volume of air movement needed to create this effect is substantial, subwoofers with dedicated enclosures and amplification have become a necessary component in all high-performance systems.
The drawback has once again been aesthetics. Subs are big and bulky. Most systems are designed with the subwoofer tucked into a corner, inevitably to be used as a plant stand. Not any more.
