The Perfect Bass Extension

Excellent performance for music, movies, and games. A perfect bass extension for Audioengine powered speakers or as an upgrade to any stereo or surround audio system.

Audioengine's S8 Subwoofer has an 8″ custom woofer and is small enough to place in a corner or hide behind furniture. The S8 delivers great bass performance and its low, tight, and smooth bass will blend well with the other speakers in your system.

Low, Tight, Smooth Bass

The S8 Subwoofer has a super-fast woofer designed for audio and home theatre performance. It features an anti-resonant steel frame and heavy-duty rubber speaker surround for accurate low end.

The S8’s bottom-firing and front-ported design means you’ll hear quick, precise bass with no distortion, even at higher volume levels.

In other words, S8 is a tight, smooth, and natural-sounding subwoofer.

Set Up in Seconds

Dual audio inputs are included on the rear panel so connecting S8 to all your gear is easy.
An auto-sleep standby feature turns the S8 Subwoofer off when you’re not playing music, so you don't need to worry about excessive power-usage.

Unique, Bespoke Design

Audioengine designs and manufactures their own speaker drivers and other critical components. In other words, the S8 is not a box-built system with off-the-shelf parts, but includes custom-designed components constructed to their specifications. What they do not fabricate directly inside their factories they have made to their specific designs. Parts such as circuit boards, transformers, magnets, and wiring harnesses, for example.

The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. 

To minimize unwanted resonances and distortion, Audioengine cabinets have thick high-resin MDF walls with extensive internal bracing. Heavy internal sound-damping material is also used to reduce unwanted sound reflections inside the cabinet.
