More info

The T800-4ad combines sound quality characteristics of Class-A designs with efficiency of a Class-D in one remarkable package. Superior sound quality is possible through the implementation dynamic switching frequency control. The addition of Constant Power circuitry produces optimized output at a range of impedances. Rockford Fosgate created Class-bd for brute power to run low frequency subwoofers, and now Class-ad offers high fidelity in a full-range configuration.
