Design and Build
The defining characteristic of the Denon DHT-S316 soundbar is its low-profile design. Standing at just under 2 inches tall, it is engineered to fit below most televisions without obstructing the screen or the TV’s infrared remote sensor. This slim, black enclosure is constructed from plastic and maintains a clean, minimalist aesthetic. The design allows for flexible placement; it can rest on a shelf or be wall-mounted using the included template and spacers, aiming for a low-visibility integration into your entertainment setup.
The wireless subwoofer is a separate unit that connects automatically to the soundbar, granting you the freedom to place it anywhere in the room to achieve the desired bass effect without dealing with a long audio cable. The overall build, as described in the specifications, prioritizes a discreet footprint. The system’s physical dimensions and weight suggest a product designed for stable placement, whether on a stand or mounted securely to a wall.
Performance and Features
Audio Performance and Drivers
At the core of the Denon DHT-S316’s performance are its two-way speaker drivers. The soundbar houses dual 1.25″ x 4.4″ mid-range drivers paired with 1″ tweeters, which are tasked with delivering detailed and crisp sound. This driver configuration works in tandem with Dolby Digital and DTS decoding to create a virtual surround sound experience, simulating a more immersive, theater-like audio field from a single bar. The system’s total power output is listed at 40 watts.
A standout feature highlighted by the manufacturer is the Denon-proprietary Dialogue Enhancer. This technology is designed to intelligently clarify speech and vocals within complex audio tracks, aiming to make dialogue understandable without constantly adjusting the volume level—a common pain point for TV and movie viewers. For low-frequency effects, the wireless subwoofer, equipped with a 1-inch driver, is intended to provide the deep, powerful bass rumble for movies, music, and shows.
Connectivity and Inputs
Connectivity is streamlined for user convenience. The Denon DHT-S316 offers two primary digital audio inputs for your TV: an HDMI port with Audio Return Channel (ARC) and an optical input. The HDMI ARC connection is particularly notable, as it allows for a single-cable setup between the soundbar and a compatible TV, simplifying connections and control. An HDMI cable is included in the box. For audio sources, you can connect devices like a Blu-ray player or gaming console directly to these inputs.
Wireless and Streaming Features
Beyond TV audio, the soundbar features built-in Bluetooth technology, enabling wireless music streaming from smartphones, tablets, or computers. This allows you to play audio from popular streaming services such as Amazon Music, Pandora, Spotify, and TuneIn. The Bluetooth range is specified as 10 meters. It is important to note that advanced wireless features like built-in Wi-Fi or dedicated app control are not listed as part of this system’s capabilities.
Setup, Support and Ownership
Setup appears straightforward, centered on the single HDMI ARC connection. The package includes the necessary cables (HDMI and optical), a remote control, power cords, and hardware for wall mounting. The wireless subwoofer requires only a power connection, as it pairs automatically with the soundbar. Users have the flexibility to experiment with subwoofer placement in the room to find the optimal spot for bass response.
Denon backs the DHT-S316 with a 3-year manufacturer’s warranty, which provides a substantial period of coverage for potential defects. The system is controlled via the included corded electric remote, which requires 2 AAA batteries.
