In larger systems, integrating multiple subs is easy and unobtrusive. Take advantage of this opportunity to get the bass off the floor and allow it to blend into the decor with the rest of the speakers. The all-new cinema subs, great bass, no space.
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.
