With breakthrough technologies such as Intelligent Phase Control™, easy settings management with its dedicated remote control, and advanced custom integration capabilities, the DNSUB12 is easily optimized to the specifics of your system.

Intelligent Phase Control™ for Flawless System Blending

Intelligent Phase Control™ provides a full 360 degrees of customizable phase adjustment, always centered around the settings of the low-pass filter. This provides the ability to tune the subwoofer for minimal group delay between speakers and a flawless blending experience between your speakers and the subwoofer. Intelligent Phase Control is available in the Descend DNSUB12 and DNSUB15 subwoofers.

Remote Control with On-sub LED Display for Adjustments on the Fly

Easily adjust the DNSUB12 volume level, phase, and EQ with its slim remote control. There’s no need to constantly get up to manually change settings or wonder if you’ve gotten them right.

Multiple Subwoofers for Smoother Bass throughout the Room

While a single subwoofer can add bass and enhanced realism to any system, it may not provide consistent frequency response throughout the room. When two or more subwoofers are properly employed throughout the room, sound waves disperse more evenly, flattening the frequency response. The result is smoother bass throughout the room, helping to eliminate boomy locations or dead spots.

Custom Integration ready for Complete Controllability

With both 12V input and IR pass-through, you have the ability to pair the subwoofer with most control systems and place the subwoofer wherever you want in the room and still experience full functionality.

Onkyo TX-SR393 5.2-Channel Audio And Video Receiver

Onkyo TX-SR393 5.2-Channel Audio And Video Receiver. It outputs up to 80W of power per channel at 8 Ohms for room-filling sound. AccuEQ sound calibration tailors the sound to your room’s specific acoustics. Built-in Bluetooth connectivity lets you listen to music wirelessly from your favorite Bluetooth-capable devices.

The Onkyo TX-SR393 is equipped with four HDMI inputs and one HDMI output. The HDMI output supports ARC for the reproduction of display-based audio, such as your TV’s built-in streaming apps. Its rear-panel easy connection guide will help you connect your receiver quickly and easily.

Dolby Atmos and DTS:X Sound

These two sound technologies mix audio in 3D space using object-based encoding as opposed to channel-based to help create the effect of sound moving all around you. Dolby Surround and DTS Neural:X find localization cues in legacy stereo or multichannel soundtracks and upmix them to simulate 3D audio.

HDR & 4K Support via HDMI

Each of the receiver’s HDMI terminals support 4K/60 Hz, HDR10, HLG, Dolby Vision, BT.2020, and HDCP 2.2. The HDMI output supports Audio Return Channel (ARC) for the reproduction of display-based audio, such as integrated apps. You can confirm the A/V input/output status via an OSD window.

Discrete Amps

The receiver’s discrete amps, high-output transformer, and large capacitors are designed to deliver high current to the speakers to help provide better speaker control for fast transient response, wide dynamic range, and clear, accurate sound.

Bluetooth Audio Streaming

Bluetooth wireless technology sends whatever is playing on your compatible mobile device, laptop, or computer to your home theater. Once the receiver has paired with and remembered your device, it can start playback automatically whenever it detects an incoming Bluetooth audio stream from that device.

AccuEQ Room Acoustic Calibration with AccuReflex

AccuEQ sets speaker parameters, such as size and distance, and sets their sound-pressure levels. It then selects the right subwoofer crossover setting and applies equalization to all your speakers. AccuReflex is designed to optimize object-based audio reproduction through Dolby Atmos-enabled speakers, resolving phase-shift caused by the path differences between directional and non-directional sounds. These features combine to help improve localization and provide a 3D soundstage with vertical movement and overhead dimensionality.

Advanced Music Optimizer

Lossy files, such as MP3s, are convenient, but data lost in the compression process results in comparatively low fidelity. Advanced Music Optimizer technology helps restore lost information for enhanced sound quality with these file types. This mode also optimizes Bluetooth streaming playback quality.

Virtual 3D Sound with DTS Virtual:X

DTS Virtual:X is designed to create an immersive 3D soundfield from any speaker layout, regardless of whether height, surround, or rear speakers are installed. It uses DSP-based algorithms to place you at the center of a multidimensional soundfield with height and surround effects, and works in large or small speakers. DTS Virtual:X works in the 3D domain with DTS:X soundtracks, other DTS formats, and non-encoded stereo.

Clear Dialogue with the Touch of a Button

The Onkyo TX-SR393 features DSP-controlled Vocal Enhancer that identifies vocal frequencies and allows you to raise or lower them to your taste using the keys on the remote or via the tone controls on the receiver’s front panel.

Zone B Line-Out

The Zone B line-out lets you connect a component with an analog RCA line input to audio sources connected to the Onkyo TX-SR393 receiver, including digital audio via HDMI, optical, or digital coaxial. Share sound to a nearby space, or connect a supported transmitter for your wireless headphones to enjoy your media without disturbing those around you.

Connect and Power Your Media Streaming Device

A rear-panel USB power output supplies power to select HDMI media streaming devices, allowing you to upgrade your home theater with on-demand network entertainment without additional power cords.

Rear-Panel Setup Guide Helps Simplify Connection

Onkyo TX-SR393 Connections to speakers and external devices are illustrated and labeled on the back panel. Images help you read the diagram upside-down if you’re leaning over the top of the receiver.

Dolby Atmos Height Virtualizer, Available via a Future Firmware Update

When playing any Dolby format, engaging the Dolby Atmos Height Virtualizer helps provide a more immersive listening experience by creating a virtual surround Onkyo TX-SR393 and height effect from traditional speaker layouts. This feature is scheduled to be made available via a future firmware update.
