Construction is excellent as is the finish. Rubber and Spikes both provided. The back offers a host of ways to configure and setup over tonal control. The bass is wonderfully accurate, tight without being overbearing. The 8" paper/Kevlar long-throw driver is mated to 200 watts of power. For a smaller to mid sized room, this Subwoofer is at home in either a pure-audio or H/T setups. This makes a great addition to a pair of book-shelf speakers.
