Audioengine S8 Subwoofer

1 Review
Excellent performance for music, movies, and games. Audioengine S8 is the perfect bass extension for Audioengine powered speakers or as an upgrade to any music system. Super compact size and wireless-ready.

Upgrade your audio

At about 11" square with an 8" custom woofer, this powered subwoofer is small enough to place in a corner or hide behind furniture. The AS8 delivers great bass performance and it's low, tight, and smooth bass will blend well with the other speakers in your system.

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.


If you decide to locate the Audioengine S8 away from your powered speakers or surround sound AV receiver, check out the Audioengine W1 wireless audio adapter or Apple’s Airport Express for high-quality wireless options. The AS8 has a built-in AC outlet on the rear panel that’s perfect for powering these great-sounding wireless products.

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.

Versatile Yet Simple Controls

Variable adjustable rear panel controls for Crossover, Phase, and Subwoofer Volume allow you to easily adjust the AS8's output and blending with your speakers. An auto-sleep standby feature turns the AS8 amplifier off when you're not playing music.

Hear the Difference

The Audioengine S8 sets a new level of audio and aesthetic quality. Even if you're not an audio enthusiast, we guarantee you will still hear a difference!

    Exceptional value


    As with all Audioengine products (my speakers are wired HD6), solid construction, thoughtful features, exceptional customer service, and great quality control.

    Adjustable crossover supports pairing with a very wide range of speakers, while independent volume control (which, when set, adjusts based on master volume) allows tailoring to individual tastes.

    Played Clapton “Unplugged”, some Oscar Peterson, and Singers & Players dub reggae on initial run; all were noticeably improved by the addition of the S8.

    Bravo !
