I read the review in this month's Stereophile Ultimate AV of Velodyne's new line of subs with built-in EQs. While I was setting up my servo 15 (before I read the article) I thought "wouldn't it be nice to have a sub that comes with a mic and test tones to automatically do it for me?" Sure enough the new "DD" line of subs do. It has a video output to display the FR, microphone, test tone generator, parametric EQ, selectable x-over slope, remote, and the usual set of controls. You still have to do it manually on the Velo (which is fun I guess) but it would be cool if you could assign a built in computer to do it. I think Velodyne is onto something that some of us here are already doing with our BFDs. Current trend is to make them smaller and decor-friendly. I believe this will the be next trend in subwoofer design.
