Baby Bloomer

摘要

Velodyne styles itself as the 'global leader in high performance, low distortion subwoofers', and few familiar with its impressive range of products would challenge that claim. Right at the pinnacle is the awesome 1812 Signature Edition, so named because it combines an 18in and 12in driver in one box - although the allusion to Tchaikovsky's famous overture is probably no coincidence. Next in the pecking order, and using the same core technology, comes Velodyne's four-model Digital Drive range. The 'baby' £2000 DD-10 is featured here and auditioned as a pair in place of one, commensurately larger subwoofer. Baby indeed, because a distinctive features of all Velodyne subs is their compactness - remarkably so for the punch they pack. The DD-10 measures just 298 x 298 x 343mm and is also relatively light at under 9kg thanks, in part, to the efficiency of its integrated, Class D amplifier. This is rated at 1250 watts continuous output power or 3kW peak! The DD-10 also utilises the smallest version of Velodyne's in-house, servo-controlled woofer which is hooked into the Digital Drive DSP module that provides for the measurement and correction of its in-room response. This Digital High Gain Servo system uses a digital accelerometer to measure and control cone excursion at a sampling frequency of 16kHz.
