We are building a new home and the contractor and audio system installer plan on putting the sub woofer on floor level in the built in entertainment center with a port at the bottom. The audio installer uses Velodyne but I said I prefer to stay with Klipsh. He said just make sure you use the front firing models. He said these may not be as good as some of the Velodyne's in this application, but will work. Anyone have experieince with Subs built in and if the RW 12 is a good unit for this. I am using RB 35 and RC 35 for speakers.
