Many Infinity subs use their RABOS System.Some Velodyne subs provide remote setting via mic which does some room correction.
subwoofers w/room correction
are there any subwoofers with built in room correction other then Velodyne and JL Audio? i am not interested in using a sms-1 or the like, just want everything in one box and want to make sure there isnt anything else out there i may be overlooking if i decide to go that route.
