"For starters, the on-board DSP room correction system is well thought out and intuitive. Having on screen display (composite and S-Video) makes the interface very user friendly. I hate reading manuals; I didn't with the Velodyne.
The on-board "SMS-1" allows for a total of 6 different memories to be stored. I have set-up theaters that have a mode for the specific sweat spot, another for a blend from the top and bottom tier. If you need a little more "oomph" you can relax the servo in 10% increments adding as much as 3db (50% more output).
For those who do not know, the servo is a feedback loop that is hooked into the microprocessor to test its exact location 16,000 times a second. That feedback loop stops the driver from over or under shooting the desired location; hence the distortion is under one percent. Typical subs generate more than 10% distortion.
Those who critique the "servo sound" (I am not one f them) can relax the servo by dialing it back or even off. This also increased the effeciency and allows for more SPL output (up to 3DB). I use this as a memory mode as well (dialed back servo). So if you feel you are on the edge of needing more "woofage" you can dial back the servo to pick up as much as 3DB or 50% increase."
