Given its modest cost, you wouldn’t expect to find a custom-designed balanced-drive power amplifier with a 300W peak power output in the active Wharfedale WH-D10 subwoofer. And you might not anticipate hearing tightly focused bass played with a combination of authority, punch, attack, quickness, and refinement not associated with subwoofers anywhere near this price class. Yet, just like the award-winning Diamond 200 Series of loudspeakers it flawlessly complements, WH-D10 is built to impress at a cost many music lovers can afford. Cognizant of looks, high-gloss lacquered front baffles and cosmetically enhanced veneers turn the Wharfedale WH-D10 an aesthetic beauty. But you probably won’t spend much time staring at WH-D10 given its ability to seamlessly blend into the room. Equally great on both music and movies, the dynamically astute Wharfedale WH-D10 counts a 10-inch long-throw woofer, continuously adjustable low-pass filter slope, low-level inputs, and dedicated LFE input among a simplified arsenal assembled with one goal in mind: Emotionally engaging, tonally realistic, heart-pumping performance that turns your A/V system into an escapist retreat. The spec sheet will inform you about its prodigious bass extension (below 30Hz) and wide 86dB dynamic range. But your ears will tell you all you really need to know about WH-D10.
