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

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. Plus, a variable phase control lets you tweak the sub's output for more precise bass response. And an auto-sleep standby feature turns the S8 amplifier off when you're not playing music to conserve energy.

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Features

Overview: The Audioengine S8 powered subwoofer is the perfect addition to your Audioengine powered speakers or as an upgrade to almost any audio system. The S8 powered subwoofer offers excellent performance for music, movies, and game. The powered subwoofer offers a compact design for easy placement. The S8 includes LFE, stereo RCA, and minijack inputs; as well as a full-range stereo RCA output.

High Power Amplifier: The S8 powered subwoofer employs a dual class A/B monolithic amplifier which is rated at 125 watts RMS and 250 watts Peak.

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.

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.

Furniture-Grade Finish: The Audioengine S8 features a custom-designed and handcrafted wood cabinet with high-gloss white or satin black finish. The cabinet is made of solid 1" thick, internally braced MDF to eliminate cabinet vibrations which means distortion-free, accurate response.

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.

Controls

Subwoofer 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 turning the Phase control (0-180°) in small amounts 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 every setting, 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.

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.

Connections

LFE In: If your AV receiver has an LFE (Low Frequency Effect) input or single Subwoofer output, connect it to the S8's LFE input. The S8's LFE input bypasses the subwoofer's built-in low pass crossover and uses your AV receiver's bass management settings.

Dual Line-Level Inputs: 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.

Full-Range Output: The S8's stereo RCA outputs provide a full-range line-level output to powered speakers or another subwoofer. This output is active whenever a signal is connected to one of the two subwoofer inputs. The volume level of this output connection is controlled by the audio input source, not the volume control on the subwoofer.

Aux Outlet: The S8 powered subwoofer is fitted with a two-prong unswitched AC outlet (11-120VAC, 60Hz/1A)

Detachable AC power Cord: The Audioengine S8 includes a detachable 6' AC power cord.

Audioengine S8 sub-woofer

Written By art, ny on Monday, September 29, 2014

Crutchfield Customer Review (What's this?)

Very easy to install, great sound with easy controls for balancing sound.

Pros: Simple and easy with great performance

Cons: on off switch located in the rear of enclosure

Extraordinary sound - worth the money!

Written By John the Geek, Richmond, VA on Wednesday, June 11, 2014

Crutchfield Customer Review (What's this?)

From the first moment I powered it on and began to feel the bass, I knew I had made the correct decision. This sub pairs so well with my AudioEngine passive speakers and Teac desktop amp that I wondered what took me so long! Now my music is great, movies on my PC are better and games are beyond immersion.

Pros: Fantastic sound, easy setup, clear directions and no hassles.

Cons: Cannot think of any.

Fills out the sound spectrum

Written By Brent, Charlottesville, VA on Friday, April 04, 2014

I added the S8 to a set of A2s for my computer music setup in my apartment and I'm very pleased with the result. When my wife and I downsized from our house (thanks for moving out, kids!) I replaced my traditional 100 watt receiver/amp/speaker/sub setup with an iTunes-based computer music system, and I was missing the deep bass I had with the subwoofer. Now I have it again. I had to reduce the sub volume level a bit so my neighbors wouldn't complain, but the overall sound is now richer and deeper. The setup was easy and the small size of the S8 fits in well with the smaller living room. I got the Satin black model to match the A2s and the Sony Bravia TV atop the dark brown, almost black Havenworth A/V credenza. It not only sounds great but looks great - hey, my wife is an interior designer, it has to look great!

Pros: Compact, easy to set up, deep rich sound.

Cons: None.

awesome base

Crutchfield Customer Review (What's this?)

I purchased the S8 sub woofer to accompany my A5 speakers. The setup took just a few mins. I know the A5 speakers sound great but adding the S8 made the sound came alive. My wife said it sounded like she was in the theaters. Awesome sound. Best set of speakers and sub I have owned.

Pros: Deep base Clear sound

Cons: None

Amazing Clarity and Power

Written By Danny, Houston, TX on Tuesday, August 14, 2012

I've had many different powered subs before that are in the price ranges of 800-1000$ and when i got these i was definetely surprised by the power they have. I tested them and i put them on 70% power, went outside my house, and saw the windows flexing from the amount of bass they produce.

Pros: Best speakers for the price, Amazing Clear low pitch sounds. Definetly Bring my Music Back To Life!

Cons: Kind of big, but hey "Big sound, Big speaker" Right?
