The proprietary Velodyne subwoofer correction system is included in all the higher end Velodyne subs as well as a standalone unit called the SMS-1. Anyone that has done much research about subwoofers has undoubtedly run across the SMS-1. A 1/3 octave smoothed, on-screen graph in real time makes adjusting and parametric eq’ing a subwoofer an exercise even the most technologically challenged can excel at. There are very few additions to a full surround system that have the impact of a room correction system. You’ll wonder how you ever got along without it. And with the addition of the Mic-5, you now have the ability to correct for multiple seating positions creating a better experience for everyone. While the Mic-5 add-on may be a bit pricy for the average consumer, I can see it as a very good investment for an installer or perhaps a group of friends that can split the cost. It is nice to be able to correct for a sweet spot, but multiple seats takes it to a whole other level. Discuss "Velodyne Mic-5 Add-on Supplementary Review" here. Read the article.
