  • Adding a Subwoofer to Your Home Theater



  • Custom Woofer
    The AS8 has a super-fast woofer designed for audio and home theater performance. It features an anti-resonant steel frame and heavy-duty rubber speaker surround for accurate low end. The AS8's bottom-firing and front-ported design means you'll hear quick, precise bass with low distortion, even at higher volume levels. In other words, this is a tight, smooth, and natural-sounding little subwoofer.
  • Furniture-Grade Finish
    Custom-designed and handcrafted wood cabinets with high-gloss white or satin black finish make the Audioengine S8 a true work of art. Cabinets are made of rock solid 1-inch thick, internally braced MDF to eliminate cabinet vibrations which means distortion-free, accurate response.
  • High Power Amplifier
    With plenty of continuous class A/B power, the AS8 internal amplifier has a dual-voltage switch and detachable
    power cord.
  • Easy Connections
    Dual line-level inputs (1/8" mini-jack and RCA connectors) are included on the rear panel so connecting AS8 to all your gear is easy. And all cables you'll need are included.
