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.

Troubleshooting

S8 Troubleshooting Tips

The following troubleshooting tips can help diagnose and correct most concerns with the S8 Wireless. 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.

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.

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.

The S8 Wireless uses a W3 for its wireless connection. The W3 is designed to “play nicely” with other wireless products but interference can happen, depending on the type of router(s) being used, other wireless systems in the area, your computer, building construction, etc.. If you are experiencing an issue with your wireless network or interference, here are some things that may help:

Please try changing the channel of your Wi-Fi router to 1 or 11. This can be done with an Apple router using Apples Airport Utility software. On most other routers, these settings can be accessed by logging on to the routers IP address through a web browser.
Please try to keep as much room between the W3s sender and receiver units, and other wireless devices as possible. At least 2 or 3 feet is recommended.
Please try temporarily moving the powered W3 sender unit as close as possible to your wireless router. Leave it there for just a few minutes, and then place it back into your setup and retest. This may allow the W3 to train itself to “steer clear” of the signal.
We have found that every now and then the placement of the computer’s antenna in relation to the USB port can have this effect on the W3. One thing you could try is to move the W3 further from the computer by using a USB extension cable. – If using a Mac laptop, try the USB port furthest away from the display (the display is where the wifi antenna is located).
Consider upgrading to a new wireless router if yours is older than 3 or 4 years. Newer model routers handle interference much better than older routers.

Speaker Setup – How to break in new speakers.
- Speaker Setup – How to break in new speakers.
  
  So you just got your brand new Audioengine speakers and you’re ready to pull them out of the box and get them set up so you can start rocking out.
  
  Straight out of the box, your speakers should sound great, but what if your speaker setup could sound better with time?
  
  One thing that you can easily do to make that new speaker setup sound top-notch is a thing called “break-in” and it’s actually really simple.
  
  So why would you want to break the speakers in?
  
  The materials we use for our speakers are quite robust, so right after manufacturing they can be a bit stiff.
  
  One way to help out with this stiffness is to break them in so that these materials, such as the rubber surrounds of the aramid fiber drivers, loosen up. As mentioned earlier, the speakers should sound great from your first listen, but after they move around a bit and loosen up you should notice smoother low end response and sweeter mids/highs.
  
  From time to time, we get asked about how to break in new speakers.
  
  The break-in period doesn’t really require anything special other than listening to music and over time your speakers will become more and more broken in.
  
  For proper break in, we generally recommend around 40 to 50 hours of at least mid-level playback before doing any critical listening. Some our customers have mentioned that they play tones or white noise while they are away, such as while they’re at work, to help the process along, but we’d recommend just listening to them normally at a medium-level during the break in period.
  
  Breaking in your new speaker setup is a simple and crucial thing to do to make your speakers sound better and open up their potential. Some things do get better with age!

How to Clean Your Audioengine Home Music System
- 1. Turn Off and Unplug:
  - Make sure your system is turned off and unplugged.
  2. Dust the Surfaces:
  - Use a soft, dry cloth to wipe away dust.
  - For hard-to-reach places, use a soft brush or a can of compressed air.
  3. Wipe Down the Exterior:
  - We do not recommend using any solvents
  - If cleaning off stains or build-up is necessary, we recommend doing so with a very small amount of mild cleaning solution applied only to the affected area, followed by quickly wiping the area dry completely.
  - Any scoured pads or objects like a ‘magic eraser’ too easily run the risk of removing sealers and top coats of the painted finish that can leave a clearly visible change in the uniformity of the paint/finish
  4. Clean the Speaker Grills:
  - The speaker grills can be gently cleaned with a vacuum, preferably using a soft bush attachment.
  - A lint roller can also be used.
  5. Clean Buttons and Knobs:
  - A dry cloth is recommend for cleaning any knobs, buttons or other surfaces
  - Be careful not to let water get into any gaps.
  6. Clean Ports and Connections:
  - Use compressed air to blow out dust from ports and connections.
  7. Let Everything Dry:
  - Make sure everything is completely dry before plugging back in and turning on.
  8. Regular Cleaning:
  - Dust your system regularly to keep it in good shape.
  By following these steps, you can keep your Audioengine system clean and working well.
How do I know if I bought from an authorized and legitimate site?
- Audioengine operates two websites, audioenginedev.wpengine.com and audioengineeu.com. If you go to any other site but these, they are not an Audioengine site. For Canada, Mexico and most of Europe and the UK, we only sell through Amazon. There are also a host of authorized retailers and sites across the US, and they can be found here. For international sales, we have distributors that operate independently, and they can be found here.
  
  What happens if I buy from an authorized site claiming to be Audioengine? Unfortunately, there is not much we can do. We are taking all the action we can to make sure those sites don’t get indexed, but we recommend you work with the provider of the card you used to make payment to get your money back.

S8 Size: What is the size of the S8?
- The S8 is 11.25″H x 11.25″W x 11.25″D
What are the QA Stickers?
- We take great pride in our products, and go through great lengths to ensure consistency and quality. For that reason, this item was randomly selected for an additional step of Quality Assurance.
How do I make my existing Audioengine Subwoofer ‘wireless’?
- You can do this using powered speakers like our A2+s, HD3s, HD4s, A5+s, and HD6s. For this, you’ll connect the W3 sender to the RCA output on the left speaker, using a 3.5mm stereo-mini to RCA “Y” cable. Then connect the W3 Receiver to the input on your S8. You can either use a 3.5mm stereo-mini to stereo-mini cable for this, or another 3.5mm stereo-mini to RCA “Y” cable; either will work fine. Both W3 units will need to be powered from a USB port. You can use USB AC power adapters, or if the powered speaker you’re using is our A5+ Classic model, you can use the USB port on it’s rear panel for the W3 sender. The same would apply to the S8 subwoofer if you have our current ‘Gen II’ model that has a USB port on the rear panel.
Are firmware updates or driver downloads needed for my Audioengine product?
- No, there are no firmware updates or special drivers needed unless you own our A1-MR multi-room speakers or our B-Fi multi-room wireless streaming device. If a firmware update is released for the A1-MR or the B-Fi, you will be notified of the update the next time you open the Audioengine Control App. If an update is needed, simply click “update” on the DEVICES page next to the product that needs to have the firmware update applied. The app will handle the rest of the process from there! Standard plug-n-play drivers that are provided by your computer’s OS are utilized when using the USB input on our A2+, HD3, and HD4 speaker models. And all of our Bluetooth speakers/products are compatible with any device that supports Bluetooth, and the A2DP profile for streaming stereo audio. This includes most smartphones, tablets, and computers. For computers that don’t include Bluetooth support out of the box, you can simply add a USB Bluetooth adapter.
What size are the screws used to secure S8 feet?
- M6 x 40mm, 6mm diameter pan head
Does the crossover on the S8 adjust the frequencies played by speakers connected to the RCA line output?
- The S8’s crossover is a variable low-pass filter, and will not adjust the audio for the RCA output connection. This is a full range line level output.
How do you set the crossover on the S8?
- The S8s crossover is a variable low-pass filter. This means it variably adjusts how high the S8 will play. Unless the subwoofer is pretty far away, you can usually leave the phase switch set to 0°. When setting up a new S8, I like to start with the crossover all the way counter clockwise and, with some music I’m familiar with playing, first get the volume “about” right. After that try making very small adjustments clockwise on the crossover, evaluating each small change from where you’ll be listening from most often. Once it starts sounding like you can localize where the sub is coming from, back it off until you can’t again. You may also need to lower the volume a touch after the crossover is dialed in, or perhaps even while you’re dialing it in, depending on the acoustics of the room you’re in, and your own preference on how present you’d like the sub to sound. Audioengine powered speakers have fixed passive crossovers designed specifically for them; this simply means that they are designed to play the frequency range they produce, so it’s not necessary to alter this when adding a subwoofer. Adding a subwoofer, such as the S8, will pick up where the speakers leave off, extending the low end response.
Can I use the P4 passive speakers with the Audioengine S8 sub?
- Yes! You would just need an amp, like our N22, to supply power to the P4 speakers and connect to the S8.
What surface should I put my S8 on?
- We typically recommend using the S8 on a carpeted floor or with some padding under the feet if you have it on a hard floor, as you may notice unwanted noise and/or vibrations from the subwoofer feet on a hard surface at higher volumes. It’s worth noting that placing your S8 on a carpeted area will not affect the sound.
Can the S8 subwoofer be used with the A2 desktop speakers? I don’t see any audio outputs on the rear of the A2 speakers?
- With the original A2s (not the A2+ model), there are two ways to connect a powered subwoofer to them. The S8 has two inputs and an output, so you could send the audio signal into the subwoofer from your source, and then use the output to connect to the A2s. The other option would be to send the audio signal from your source into the A2s, and then use the opposite connection, meaning the input that is not being used, as an output to connect to the input on your subwoofer. Both inputs on the A2s will act as outputs when audio is sent into either the A or B input; this simply means that if you’re sending audio to the mini-stereo input of your A2s, the RCA input will actually output to the subwoofer.
Can the S8 subwoofer be made wireless?
- Yes! If you already own an S8, you’d just need a wireless adapter like our W3. If you’re looking to buy an S8, consider getting our S8 Wireless that comes with the W3 included.
How do I control the volume of my S8 subwoofer? Do I have to reach behind the S8 each time I want to raise or lower the volume?
- Most Audioengine powered speakers have variable RCA outputs for use with a subwoofer like the S8 (the exceptions being the B2 and the 512). This means that the output of the speakers and the RCA output will go up and down together. So once you dial in the volume of your S8, you should be able to adjust the volume from the speakers, or your source device. Either way the subwoofer and speakers should stay in balance as the volume is raised and lowered.
Can I use a subwoofer with the B2?
- The B2 is designed as a standalone speaker, it has inputs for Bluetooth and 3.5 mm mini jack. It does not have an output, so unfortunately you cannot output from a B2 to a subwoofer.
Why doesn’t the USB power port seem to charge my device?
- The USB port can provide around 500mA, which is standard for high powered USB 2.0 devices; these are perfect for using a W3 or B1 for instance. However, when trying to charge a iPad or iPhone for example, they require around 1000mA to charge with the screen on (the iPad’s included USB charger actually provides around 2100mA to speed up charging with the screen on). If your device is at a higher battery level it should work fine to plug it in to the USB power port to maintain the battery while listening to music (with the screen on it will always show “not charging”). If the battery is low though, we’d recommend plugging it into the charger that came with it.
