S8 Powered Subwoofer
Pro Tip:
Place the S8 under your desk or against a wall in larger rooms. The S8's down-firing design provides deep bass, making it ideal for home theaters or living rooms. If you have close neighbors or need a compact option, consider the S6 for its desktop-friendly design.

Custom Components
Audioengine designs and manufactures our own tweeters, woofers, and other critical components. In other words, these are not “box built” speakers with off-the-shelf parts but custom-designed to our specifications. What we do not fabricate directly in our factory we have made to our designs (parts such as transformers, magnets, and wiring harnesses, for example). The cabinets, drivers, bass port designs, amplifiers, and crossovers are all painstakingly tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires much less power than passive speakers and a separate integrated amplifier or similar A/V components.
Quickstart Guide
S8 Quick Setup
Here are two of the most common connection options to connect the S8 subwoofer to your music system, stereo receiver, or powered speakers.
Music System to S8 Sub using mini-jack audio cable
1) Connect a 3.5mm mini-jack audio cable from an output of your stereo receiver, powered speakers, or any music system with an output, to the S8 subwoofer input.
Note: Your receiver’s manual should indicate which subwoofer connection is most appropriate.
Powered Speakers or Stereo Receiver to S8 Sub using RCA audio cable
1) Connect an RCA stereo cable from an output of your stereo receiver, powered speakers, or any music system with an output, to the S8 subwoofer input.
Note: If your stereo receiver or music system has a single RCA sub out or LFE output, connect an RCA cable from this output to the S8 sub RCA left (L) input.

Troubleshooting
S8 Troubleshooting Tips
The following troubleshooting tips can help diagnose and correct most concerns with the S8. We have attempted to make this list as comprehensive as possible, so some of these may not apply to your issue, but please go through each tip.
For trouble getting the S8 to “wake up” from standby mode, try turning the volume up on your source or speakers until you hear the S8 kick in. There is a minimum volume threshold to meet before the S8 will play.
If the power indicator on the S8 rear panel is not illuminated, try these tips:
- Verify that the AC power cord is connected to the S8 rear panel and to a working AC power outlet.
- Check that the power switch on the S8 rear panel is in the ON position and the volume control is not turned all the way down.
- Confirm that the rear panel voltage selector matches the operating voltage in your country or region.
- If the power indicator on the rear panel still does not illuminate, check the fuse in the rear panel. If the fuse is blown and needs to be replaced it is important to replace with same fuse type and value.
If the S8 is powered on but you are experiencing an audio-related issue, try these tips:
- Check that the cables from your music source to the S8 are properly connected by unplugging the cables and then reconnecting. Try using the mini-jack (Input B) as well as the RCA connectors (Input A) to see how the sub reacts.
- Check that the volume knob on the rear panel is not set to minimum volume.
- Verify that the volume levels of your audio source components, computer, etc are not set to minimum volume or powered off.
- If you are using any wireless adapters or other products with your sub, please remove the wireless device (temporarily) and connect the source directly to the sub.
