Velodyne's fourth subwoofer series, the Digital Drive Series was introduced in 2003 with a new patented driver and method of servo control. David Hall's ground breaking on board Auto and Manual Room Optimization and EQ calibration using an included calibrated microphone and Sweep Tone CD provides an audible and visual view of the in room response of the main speakers beginning at 200Hz and the affects of the subwoofers adjustments through the crossover region and on down to 15Hz to six different memory presets. I believe the initial price for the DD-12 was $2999.
The Morgan Hill CA. company introduced the completely redesigned DD-Plus series in 2011. A new cabinet and massive servo-less driver design that provides even lower than the .5% THD of the previous DD series while eliminating the servo correction time.
DD-Plus' Room Optimization was also refined and added the variable drag and drop Frequency Response and Parameters Screen which adjusts Parametric Filter Frequency level / slope as well as changes to Q (bandwidth) Parametric Filter.
Sounds complicated but the visually audible adjustments are simply made from the listening position to closely match the low frequency presentation of the main speakers to the subwoofers crossover region and saved to memory.
Velodyne Acoustics has been sold to Audio Reference of Germany who currently provides a worldwide network of sales and service.
