Audioengine  |  SKU: S8B
Colour: Black


Add more bass to ANY audio system with the Audioengine S8 Powered Subwoofer.

Complete with our Isolation Elastomer Feet to reduce vibration and resonance so you'll experience cleaner, tighter bass.

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

Audioengine S8 Subwoofer provides great bass performance for music, movies, and games.


  • EASY SETUP: Twin audio inputs are supplied on the rear panel so linking S8 to all your equipment is easy. An auto-sleep standby function switches the S8 Subwoofer off when music is not being played

  • COMPLETE CONTROL: An ideal bass extension for Audioengine powered speakers or as an upgrade to any audio system

  • WIRELESS READY: If you want to place the Audioengine S8 away from your powered speakers or AV receiver, you can use the Audioengine W3 Wireless Audio Adapter for top-quality wireless

  • VOLUME CONTROL: Simply dial in the volume of the S8, then adjust the volume from the speakers, or your source device. Either way the subwoofer and speakers should stay in balance as the volume is raised and lowered.
  • VARIABLE CROSSOVER: The crossover is a variable LPF which adjusts how high the S8 plays. Audioengine powered speakers have fixed passive crossovers designed for them so they play the frequency range such as S8 will pick up where the speakers leave off, extending the low end response.

  • BUILD QUALITY:  Little expense has been spared building the S8. From the custom ¾” thick cabinet to the engineered isolation elastomer feet, we loved the feel of the S8. At 30lbs, you can literally feel the quality.
