A specialized speaker, referred to as a subwoofer, is responsible for that deep bass experience. 1  The subwoofer is designed only to reproduce the lowest of audible frequencies. In home theater, this is often referred to as LFE (Low Frequency Effects.
The VTF series subwoofers are the most adjustable subwoofers in the world. It's like buying 10 or more different subs for the price of one. For a given budget, you can design it to go low, or play loud, or have a ported subwoofer or sealed subwoofer, tight bass or full bass, but not all at the same time.
