3 new designs for 2006! Ultra light-weight (only 4 lbs!), the RockStars are equipped with top-of-the-line drivers from JL Audio or get just the cans and install your own speakers! To combat the "coffee can sound" the RockStars are engineered with vibration and resonant damping materials. Available in chrome, black, or custom powder coat. Rigid (w/tamper resistant hardware) or quick-release swivel mount available.
