The Sound Quality

One of the most important considerations when assessing the worthiness of a speaker or subwoofer is of course the sound quality. You don’t want to invest in any sort of sound equipment only to discover that it provides low-quality, inaudible sound.

Impressively, this unit produces powerfully, tight and smooth bass that is more than likely to cater to the majority of your home listening demands. It does not create a lot of distortion even when listening to audio at higher volumes.

While it copes exceptionally well with heavy bass sounds, it also enhances the quality of other varieties besides music such as TV and movie audio. The build quality of this unit is most definitely reflected in the quality of the sound that is produced.

If you are looking for a subwoofer that isn’t going to disappoint in terms of sound quality and experience the Audioengine S8 provides a strong contender.

Auto-Sleep Power Saving Mode

A feature that we particularly favor is the auto-sleep power-saving mode. As implied, this feature will automatically stop the unit from operating if it is unused for an extended period.

Ultimately, this will help to preserve power because the unit isn’t operating unnecessarily.

Wireless Connectivity

Many speakers, particularly those from the Audioengine range can be wirelessly connected. Although this isn’t the case with the S8 subwoofer, it is possible to invest in the Audioengine W3 wireless adapter which will transform this subwoofer into a wireless-ready unit.

Ultimately, this isn’t going to deter from how well the unit performs. It is also unlikely that the wires are going to be an eyesore because they typically tend to be placed in more hidden areas of the home.

The Build Quality And Durability

The S8 subwoofer has been made from high-quality materials such as the 15.6mm thick MDF cabinet and elomaster feet.

Aside from this, it also has an anti-resonant steel frame and heavy-duty rubber surround. Whilst this is of course evident in the feel and robustness of the unit, it is also reflected in the quality of sound that is produced.


A great thing about this subwoofer is that it can complement most home setups. The versatility of this unit means that it can be used to listen to music but it can also be connected to built-in or external amps, video games consoles, CD and DVD players, and televisions.

Because of this, you aren’t solely restricted to musical applications because it can be used to project TV and movie audio too. Additionally, the dual line-level input allows you to connect the necessary cables for your equipment with ease.

Simple Controls

Each of the controls are displayed on the rear panel of the unit making it easy to use, particularly for those who lack previous experience of using a subwoofer. While the power button and cable connection are positioned at the bottom of the panel, at the top you will find the input ports.

There are also controls for the crossover, phase, and volume so you can alter them according to your environment and requirements. Just below, the phase controls there is a light that will illuminate green when the unit is in use, though this will transform to amber when standby mode is activated.

It is also fairly easy to set up which is again going to be appreciated by those who are new to using a subwoofer. As a result, you can begin using your equipment and enjoy the high-quality sound in a matter of minutes.

Should you require assistance when attempting to use this subwoofer you are provided with a quick start guide which can be referred to as and when required for guidance when using the unit.
