With its variable crossover and phase-adjustment features, the high-performance NuForce W-1 subwoofer is designed to operate seamlessly with our Icon and S-1 systems for a low-end extension to 50Hz. In terms of tempo, speed and compatibility, the lightning fast response of the W-1's class-D amp permits the subwoofer to operate in perfect alignment with our S-1 speaker. Clearly, in terms both of looks and performance, the Icon, S-1 and W-1 are best of breed. Better yet, the W-1's adjustable crossover permits our compact subwoofer to work equally well with any bookshelf or desktop speaker.
As a matter of practical application, for a typical subwoofer crossover at 120 Hz, one wavelength of sound will be 9.4 feet long. For every 9.4 feet of distance difference between main speakers and the subwoofer from the listening position, there will be a 360 degree (i.e., one wavelength) phase shift. If the distance difference is half this, or 4.7 feet, then the main speakers and subwoofer will be out of phase by 180 degrees, thereby creating an audible notch at the crossover frequency. Continuously variable phase alignment allows the phase of the subwoofer to match that of the main speakers at the crossover frequency, at least for one listening position.

In a near field listening position where the speakers and subwoofer are very near the listener, the phase should be left at 0.

When used with S-1, the recommended Crossover Frequency setting is 80Hz.
