Editor’s brief: So, you are working from home. Or perhaps you are a SOHO or startup entrenepreneur. Decent background audio, or that occasional ramp-up to a room full of sound, is what you are looking for. While your space, whether a room at home or a small office, may just be air-conditioned, you want an efficient subwoofer to neatly sit at a corner, blending in with your design ethos or personal style. The Audioengine S6 subwoofer with a Class D amplifier may just be the box for you. Read more below.

SINGAPORE – The Austin, Texas-based speaker manufacturer Audioengine has released the S6, a powered subwoofer that excels in terms of both sound quality and portability. S6 is the best way to supercharge your desktop, home theater, or gaming setup with its 210 watts of power in a compact design. The S6’s front-firing woofer in a sealed box allows for surprising low-frequency extension and impact.

Powerful bass extension

While the S6 is a small speaker, it packs a punch and is capable of producing a large soundstage thanks to advancements in audio technology, and Audioengine is keen to highlight this fact. Because of its small size (10″H x 10″W) and light weight (15 lbs), the S6 is an ideal bass extension for a desktop computer, gaming rig, home theater system, or any other compact setup.

Small sub, big sound

The S6’s 6″ long-throw woofer and highly efficient Class D amplifier produce sound that must be heard to be believed. Plus, the bass is tight and deep thanks to the sealed box’s low frequency response (33Hz). You can fine-tune the sound by adjusting the crossover frequencies anywhere from 40 to 130 hertz.

The S6, with its 210 watts of power, can easily fill most rooms, and its powerful sound for its size makes it superior to other compact subs on the market.

Seamless integration

The S6 has two analog audio inputs, allowing you to connect two separate audio systems. Do you wish to reduce your energy consumption? Selecting the S6’s energy-saving auto-on mode allows it to detect when a signal is being sent from your audio source, allowing it to turn on only when necessary.

Are you interested in wireless connectivity? The USB charging port makes the optional W3 system from Audioengine easy to bring along and set up wherever you like.
