Featuring a spun aluminum cone, high-strength rubber surround, and copper-wound Kapton voice coil, it delivers deep, precise bass with 92dB sensitivity and a frequency response from 26Hz to 500Hz. Its compact dimensions and versatile mounting options make it the ultimate choice for audiophiles craving powerful bass without sacrificing cabin space.

## Description

By installing the subwoofer downward, the AS down-firing enclosures optimize bass response with superior efficiency for richer, deeper, heart pounding low frequency sounds regardless of the enclosure installed position. 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.
