The sleek design of the AS enclosures allows for installation anywhere in the vehicle, they can be installed vertically or horizontally. The durable MDF wood construction is designed to reduce vibration. Additionally, a special bonding sealer is used to create an air-tight seal to increase joint strength as well as bass reflex. The spun aluminum cone stays rigid even with the most powerful bass notes. Alphasonik's compact down-firing enclosures perform superbly, producing extreme bass with minimal space.

Review: Nice bass - Really filled in the low end on my system. Installed in a 2014 Raptor SCAB
Review: Great little sub woofer - I put this in my Armada to replace my old one. It's not crazy or anything. It's not going to blow out your windows or win and contests. But it does rattle the truck and you can hear it coming up the street. The build is pretty nice and compact. I'd buy it again
