The best amplifier for this application is a Class-D switching amplifier. One of the reasons a Class-D amplifier is optimum for this application is that it has a dramatically increased efficiency, especially at lower frequencies. A typical Class A/B amplifier is only 50% efficient. A Class-D amplifier, on the other hand, can be 90% efficient. A Class-D amp also puts out more power with less heat and less power consumption; ideal for use as a subwoofer amplifier.
The S4/8 uses a proprietary, ultra-efficient, discrete MOSFET switching amplifier with output capability of up to a full kilowatt. The design provides extraordinary control with high-damping and great thermal stability, so that you can play the most demanding sources continuously at high volume.
The Transducers
The transducer used in a servo system must be strong enough to withstand the high current approach of the servo, and yet delicate and light enough to react extremely quickly. The S4/8 subwoofer features four 8-inch woofers that are designed with ribbed aluminum cones, that are lightweight and yet inherently stiff. Our aluminum cones exhibit no resonance or cone flexure anywhere near the frequencies at which the subwoofer operates. The lowest break-up mode (where there can be any chance of distortion at all) is at 6,000Hz – far above the 25Hz to 120Hz frequency response of the S4/8. Therefore, the driver is a perfect piston within the frequencies used, and exhibits very low cone- breakup distortion.
