You should spend your time experiencing incredible bass, not setting up your subwoofer. Simply connect the wireless transmitter to an output on your stereo receiver or powered speakers. The wireless receiver plugs directly into the S8 subwoofer and just like that, you’re done!

Excellent low-end performance for music, movies, and games. A perfect bass extension for Audioengine powered speakers or as an upgrade to any music system. The S8 Sub 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.

Experience Incredible Bass

Many people struggle with finding the best, super-fast woofer designed for audio and home theater performance. That’s why the S8 features an anti-resonant steel frame and heavy-duty rubber speaker surround for accurate low end. The S8 Subwoofer’s bottom-firing and front-ported design means you’ll hear quick, precise bass with no distortion, even at higher volume levels for a tight, smooth, and natural-sounding wireless sub.

Questions & Answers

  • Some people want to upgrade the audio on their TV's but aren't necessarily interested in surround sound. Can I hook up Audioengine speakers to my TV instead of buying a surround sound system or soundbar?

    Audioengine speakers can be easily connected to the audio output on your TV set. Any of our speakers will provide a greatly enhanced TV audio experience with a wider soundstage and better imaging than most sound bars.

  • Do Audioengine speakers have an auto-sleep, idle, or auto-power-off function? Can I leave them on all the time?

    Yes they do! They are equipped with a power-saving circuit that turns off the speaker's final stage amp. This idle mode activates right after you stop playing music. Due to this power-saving function, it's perfectly fine for the speakers to stay on all the time!

  • Connecting an S8 subwoofer to A2+/A5+

    Your A2+/A5+ have a variable RCA output located on the rear panel of the left speaker.  This connection can be used to connect an S8 Powered Subwoofer (or any self-powered subwoofer) for extended bass response.

    You can also add a W3 Wireless Adapter to make this connection wireless as shown below.

  • What size are the screws used to secure S8 feet?

    M6 x 40mm, 6mm diameter pan head

  • Is Audioengine able to ship orders outside of the US?

    We do not sell internationally directly from our website, but you can buy locally in many countries around the world! To buy our products from a local seller, visit this link and enter your location into the map:


  • Are Audioengine subwoofers magnetically shielded?

    Yes! All of our speakers and subwoofers are directly video shielded and allow the user to place the speakers/subwoofer within a few inches of a video monitor. This shielding also offers protection for hard-drive digital music players.

  • Can I use Audioengine speakers with an existing Sonos setup?

    Absolutely!  You can add a Sonos Port(https://www.sonos.com/en-us/shop/port.html)to your Audioengine powered speakers, or a sonos Amp (https://www.sonos.com/en-us/shop/amp.html) to your Audioengine passive speakers to integrate them with your Sonos speakers.
