Velodyne Digital Drive Plus 18 subwoofer
Subwoofer technology is moving fast, with automated room equalization and system integration now a reality. A wave of new products has appeared in the past five years, all using different approaches to solving the problems of optimizing subwoofer response in listening rooms.
Velodyne ULD-18 & ULD-15 subwoofers
Velodyne introduced their series II subwoofer line in the fall of 1988, and it seems timely to review their largest, most powerful unit, the ULD-18. As the line's flagship, this Velodyne subwoofer represents the most sophisticated and expensive system offered by the company. It is sold as a system, complete with driver, enclosure, amplifier, control unit, electronic crossover, and servo cable and circuitry. Velodyne's unique servo circuitry, manufacturing techniques, and aggressive sales technique emanate from the company's designer, David Hall.
Wilson LoKe subwoofer
Piece of cake, thought I. All I needed to do to review Wilson Audio Specialties' smallest active subwoofer, the LōKē ($8950 each in standard finish), was describe how low a pair goes in my room and how cleanly they woof.
As I was soon to learn, though, there was a lot more to reviewing LōKēs than that. Why? Because a pair of LōKē subwoofers does more than reinforce the already deep bass extension of the Wilson Alexia V loudspeakers with which they are now paired in my system. Therein lies the tale.
