You need to do three things to be a perfect subwoofer: move a lot of air, control distortion, and blend with the satellite speakers. And do it in my room, not just in some perfect lab.
Velodyne figured out the first two back in 1983 with the High Gain Servo (HGS) series that combined stiff long-throw drivers powered by high-watt amps (to move a lot of air) with servo-controlled feedback loops (to reduce distortion). This allowed even the tiny HGS-10, which I reviewed in issue #84, to provide bass down to 20 Hz at volumes as loud as you want. But it's taken 20 years of development to get that last part.
Which brings us to the Digital Drive series, and specifically the DD-10. The cabinet has grown a tad from the HGS-10, but it's still under a foot in height and width so it fits into my bedroom corner. Frequency response is now rated down to 18 Hz with the same
