About the Audioengine S8

Big bass in a small box

Add deep, low-frequency thrills to your music, movies, and video games with Audioengine's S8 powered subwoofer. It makes the perfect companion for your Audioengine speaker system, or a fantastic upgrade to any music system that needs some extra low-end kick. The S8's custom down-firing 8" woofer delivers tight, punchy bass that blends in seamlessly with the other speakers in your system. Its rock-solid, hand-crafted cabinet features internally braced one-inch thick MDF construction with a beautiful high-gloss white or satin black furniture-grade finish. This subwoofer's super-compact build allows for easy out-of-the-way placement behind the couch or under your computer desk, but it looks so good you'll want to display out in the open.

Easy connections

Audioengine makes it easy to integrate the S8 with your existing system. You can hook your receiver or other audio components up to the sub through its LFE or dual line-level inputs featuring both minijack and RCA connections. The sub's line-level outputs also give you an easy connection to your powered speakers. Adjustable rear-panel controls for crossover and subwoofer volume allow you to easily match up the S8 with your speakers. And an auto-sleep standby feature turns the S8 amplifier off when you're not playing music to conserve energy. And with an Audioengine W3 wireless adapter, you can make a wireless connection to your speaker system.

Features

8" Woofer: The S8 has a super-fast, long-throw, custom 8" woofer designed for audio and home theater performance. The 8" woofer features an anti-resonant steel frame and heavy-duty rubber speaker surround for accurate low end. The 8" woofer is down-firing and offers low, tight, and smooth bass that will blend well with the other speakers in your system.

High Power Amplifier: The S8 powered subwoofer employs a class D amplifier which is rated at 125 watts RMS and 250 watts Peak.

Bass Reflex Cabinet: The Audioengine S8 powered subwoofer utilizes a bass-reflex (ported) enclosure with a front-firing port for added efficiency, high volume level, an deeper bass. The cabinet is made of solid 15.6mm thick, internally braced MDF to eliminate cabinet vibrations which means distortion-free, accurate response. This custom-designed and handcrafted wood cabinet comes in a high-gloss white or satin black finish.

Controls: Variable adjustable rear-panel controls for Crossover, Phase, and Subwoofer Volume allow you to easily adjust the S8's output and blending with your speakers.

  • Volume Level: The Volume control is for matching the subwoofer speaker volume to the level of your speakers. Keep the volume low when first setting up your system and then adjust to your preferred level using different music and/or video sources.
  • Low Pass Crossover: The Crossover control is used to set the subwoofer high frequency cutoff point, which is the point at which the subwoofer transitions to your other speakers. For example, if the Crossover control is set to the 50Hz mark then the sub will play all frequencies up to 50Hz. All frequencies from 50Hz and higher will then be played by the other speakers. Fine-tune the Crossover setting (50-130Hz) by ear for the smoothest blend with your main speakers. The best setting of the Crossover control will depend on speaker placement, room characteristics, and personal preference.
  • Phase Adjustment: The Phase control is used to blend the sound of the subwoofer with the other speakers in your system. Phase is the degree to which the subwoofer speaker and other speakers are moving in and out at the same time. Once you have chosen a location for your subwoofer, try changing the Phase Control between 0° and 180° while you listen for the most bass from your favorite listening position. Sometimes no difference will be heard. There is no correct Phase setting and it is not uncommon for the subwoofer to sound similar at both settings, depending on your room and location of the subwoofer. If you don't hear a difference go ahead and set the Phase knob to the 0° position.

Line-Level Inputs: The S8 is equipped with a set of stereo RCA jacks which can be used as a left/right stereo RCA input or as a dedicated LFE input. There is also a minijack (3.5mm) input.

  • LFE Connection: If your AV receiver has an LFE (Low Frequency Effect) input or single Subwoofer output, connect it to the S8's "Left/LFE" input. The S8's "Left/LFE" input bypasses the subwoofer's built-in low pass crossover and uses your AV receiver's bass management settings.
  • Stereo Connection: The stereo RCA inputs and minijack (3.5mm) input are line-level audio inputs used for connecting your audio source's audio output (lacks an LFE or subwoofer output). Both inputs are active, so no switching is required if you wish to use inputs from two different audio sources plugged in at the same time. You will use the subwoofer's built-in low pass crossover.

Optional Wireless Kit: The S8 powered subwoofer's rear-panel 3.5mm input and USB (type-A) port allows connection of Audioengine's W3 wireless audio kit (sold separately). The W3 consists of a wireless receiver which plugs into the S8's rear-panel 3.5mm input and USB port, and a wireless transmitter that plugs into your AV receiver's subwoofer/LFE output. The transmitter contains a male 3.5mm jack, so in most cases you will need a minijack-to-RCA adapter (sold separately). By utilizing the W3 wireless audio kit, you won't have to run a subwoofer cable from your AV receiver to the powered sub.

Placement: This powered subwoofer is small enough to place in a corner or hide behind furniture. The subwoofer is magnetically shielded for safe placement next to your televisions. Here are three locations to try out for best performance.

  • Corner Placement: Placing the powered subwoofer in a corner usually increases subwoofer loudness. Typically the front right & left corners sound the most natural, though rear corner placement is also an option.
  • Wall Placement: Placing the powered subwoofer along a wall tends to give moderate bass performance with increased audio quality over corner placement.
  • Alongside Front Speakers: Placing the powered subwoofer alongside one of the front speakers may blend better with the overall system, but can also sacrifice some subwoofer loudness.

Note: At least 3"of clearance around the cabinet with good air circulation is recommended. Never cover the subwoofer or place it where the built-in amplifier could be covered.

Auto Standby: This indicator LED will be Green when an input signal is present (music playing) and Red when no signal is present (power-saving standby mode). The S8 subwoofer will automatically enter Standby mode after 15 minutes when no signal is detected.

Thermal Overload Protection: The Audioengine powered subwoofer is protected by an internal thermal sensor. If it runs for an extended period of time, beyond tits designated power rating, the thermal sensor will engage and shut down the amplifier. If this occurs, turn off the power switch, lower the volume level, and wait five minutes before restarting the system. This is a normal protection feature and does not indicate a malfunction.

Customer Q&A

11 questions already asked

Q
Can I connect this subwoofer to my current 2+ wireless speakers? (my 2+ speakers are currently hard-wired to my computer vs. wireless, fyi)
[ Mike  Jun 02, 2021 ]
1 answer
A
I am running my S8 hard wired into the output RCA plugs on my 5+ speakers which are hard wired to am ipod doc and a portable CD player. The S8 works great and you can adjust volume of bass and cutoff range. Very happy with my setup!
[ MIKE  Jun 07, 2021 ]
Q
does this subwoofer work with a Denon M41 system?
[ William  Jan 05, 2021 ]
1 answer
A
Absolutely, just run a subwoofer cable from the "Subwoofer" jack on the back of the M41 to your Audio Engine S8's "line level" input jacks. If you want to get fancy, you can use an AudioQuest FLX-X RCA Y-Adapter (1-female-to-2-male audio) since the S8 has two input jacks.
[ Robert  Apr 24, 2021 ]
Q
Can it be used wirelessly like the A5+ speakers? (E.g. with Bluetooth) or do they connect directly to the A5+ speakers?
[ Dave  Dec 12, 2019 ]
4 answers
A
It's a great speaker but I do not believe it is bluetooth
[ Clyde  Dec 13, 2019 ]
A
I have this hooked up directly to the surround receiver with the subwoofer outputs. Audioengine does sell an adapter kit to use bluetooth
[ Jack  Dec 12, 2019 ]
A
It connects to the speakers and is plugged into a wall outlet.
[ Colin M  Dec 12, 2019 ]
A
They connect directly but you can use a B1 Bluetooth receiver to make it witeless
[ Michael  Dec 12, 2019 ]
Q
I have Klipsch 51-M bookshelves and space limitations. Will S8 enhance my system? Room size is Medium w/ 10ft. ceilings Thanks
[ Julian  Oct 08, 2020 ]

I have the Kanto U4 bookshelf and added the AE S8, I also have 10 foot ceilings. I use this set up primarily for my record player and the Kanto U4 also allows you to connect via Bluetooth. The added AE sub really filled out the sound and has good adjustments to get the level and type of bass you want. My room is 16x20 and I keep mine at about 42 hrtz for the crossover and Ive never needed to turn the volume over half or it will shake and rattle stuff on shelves.
