Introduction
We were introduced to the Velodyne SMS-1 system at the CEDIA show in Indianapolis last year and were instantly impressed with its potential for improving how subwoofers interact with the room. The SMS-1 is basically Velodyne’s flagship Digital Drive room correction software offloaded into a standalone system that allows it to be used with any (even *gasp* non-Velodyne) subwoofers. The SMS-1 is essentially an 8-band parametric EQ with variable frequency, Q, and gain that shows you a real-time smoothed graph of the room’s low frequency response from 15Hz to 200Hz via an on-screen display.
