Meet Your Home Music System's New Best Friend

The S8 is perfect for music, movies, and games. It's a great extension for your Audioengine powered speakers or as an upgrade to any music system.

4 Ways to Complete Your Soundstage - What Are You Missing?

With an Audioengine home music system, enthusiasts have a solid foundation for exceptional audio, right out of the box. However, to unlock the full depth of your music, integrating a subwoofer like the Audioengine S8 is essential. A subwoofer adds a new dimension to your music, especially in tracks rich in low-end frequencies. It enhances the depth and resonance of the bass, introducing you to an entirely new music experience, with bass that is reminiscent of your favorite live concert. The S8 offers 23hz - 38hz more audio you're not going to hear without it.

Set up in Seconds, Consume Less Power

Dual audio inputs are placed on the rear panel so connecting the S8 to your gear is quick and easy. The auto-sleep standby feature turns the S8 Subwoofer off when you’re not playing music, so you don't have to worry about draining power after the dance party's ended.

When Your Speaker Cord Feels More like a Leash

One way to get the most out of your subwoofer is proper placement. With the Audioengine W3 Wireless Audio Adapter, you can place the S8 anywhere you want, without getting tangled up in the cord. What's best, with the S8, you won't lose any sound quality. W3 Wireless Audio Adapter sold separately.
