Our take on the Polk Audio MagniFi One

We keep hearing the same thing from our customers — TV dialogue is getting way too hard to understand. We'd love to put the blame on mumble-mouthed weather guys or brooding actors who think whispering their lines make them seem more important or interesting. But we know the truth: modern television speakers are small and often pointed in the wrong direction, resulting in tinny sound, and speech suffers the most.

Polk Audio Magnifi One in room setting

Polk's MagniFi One sound bar/sub combo keeps your TV setup tidy and delivers easy-to-understand speech.

"What was that?"

We keep hearing the same thing from our customers — TV dialogue is getting way too hard to understand. We'd love to put the blame on mumble-mouthed weather guys or brooding actors who think whispering their lines make them seem more important or interesting. But we know the truth: modern television speakers are small and often pointed in the wrong direction, resulting in tinny sound, and speech suffers the most.

Solve this problem with the Polk Audio MagniFi One sound bar, which features the company's patent-pending VoiceAdjust™ technology. VoiceAdjust lifts the sound of speech so that it's easy to make out, regardless of what you're watching — or how loud. Even soft-spoken dialogue comes through crystal-clear, so you can quit hitting that rewind button. There's even separate volume control, just for voice.

Simple connections, listening modes, and Bluetooth

Hooking up the MagniFi One Sound Bar is quick and easy. It connects to your TV with just a single audio cable. Using the included optical digital cable lets you take advantage of the bar's built-in Dolby® Digital decoding. You can also choose between three listening modes — Movies, Music, and Sports — to help tailor the sound to what you're watching.

Speaking of connections, the MagniFi One also has built-in Bluetooth. You can wirelessly play tunes from your smartphone or tablet through the sound bar's powerful drivers.

A convenient wireless subwoofer

Polk included a sub with a 7" woofer to deliver satisfying bass for high-energy action scenes and music. It connects to the sound bar wirelessly, which makes it super easy to find a place for it in your room — you'll just need to plug it into a wall outlet for power. Polk built in a time alignment feature to ensure that the sound bar and sub fire accurately together, for optimal sound.

Product Research


Active Soundbar Speaker: The Polk Audio Magnifi One soundbar speaker houses two 3" x 1" full-range drivers powered by a built-in 100 watt amplifier. The soundbar's critically tuned ports provide optimum blending of the full-range drivers with the included wireless powered sub. The Magnifi One soundbar speaker employs two of Polk's proprietary technologies for exceptional performance. The Magnifi one soundbar speaker employs two of Polk's proprietary technologies for exceptional performance.

  • VoiceAdjust Technology: VoiceAdjust Technology improves vocal intelligibility and dialogue levels. You can adjust dialog level independently from the soundbar speaker system's main volume control.
  • Full Complement Bass Drive: Polk's exclusive Full Complement Bass Drive Technology in the soundbar improves lower midrange, upper bass tonal richness, fast transient response and overall output capability.

Wireless Powered Sub: The wireless powered subwoofer features a down-firing 7" woofer and port in compact bass reflex enclosure. The 7" woofer is powered by a built-in 140 watt amplifier. The powered subwoofer receives it audio signal wirelessly (up to 30') from the system's soundbar, so there is no subwoofer cable to connect. You will need to connect the powered sub to an AC outlet. You can adjust the volume of the sub independently from the system's overall volume.

Dolby Digital + DSP Presets: The Polk Audio Magnifi One soundbar speaker system supports Dolby Digital (up to 5.1ch) sound processing through its optical digital input. Pre-set DSP soundfield modes (Movies, Music, Sports, and Night) tailor the system's sound for optimum performance. The Night mode instantly reduces the soundbar system's master volume and bass impact, while increasing voice & dialogue level, for low-volume listening.

Analog + Digital Connectivity: The Polk Audio Magnifi One soundbar system provides both analog (3.5mm) and digital (optical) connectivity for your TV and other source components.

  • Optical Digital Input: The soundbar features a single optical (toslink) digital input to connect your flat-panel TV. The optical input can decode and reproduce Dolby Digital 5.1 program material. The soundbar's digital input also supports 2-channel PCM. An optical cable is included.
  • Stereo Minijack Input: The soundbar is equipped with an analog stereo minijack (3.5mm) input to connect your television (which may lack an optical digital output). If your TV is equipped with stereo RCA outputs, use included stereo minijack-to-RCA adapter along with the included stereo minijack cable.
Note: The digital optical output terminals of most newer flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby Digital/DTS surround sound from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch stereo from sources connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or satellite/cable box).

Bluetooth Audio Streaming: The Polk Audio Magnifi One soundbar system supports Bluetooth A2DP which allows you to wirelessly stream audio from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows Phone/PC, Mac laptop/computer and more. You'll be able to stream stored music or music apps from your Bluetooth-enabled device to the soundbar speaker system. You will continue to your Bluetooth-enable mobile device for music navigation and to view song/artist information.

Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Polk Audio Magnifi One soundbar speaker system.

Remote Control: The included IR remote control provides wireless operation of the system. You can also program the Magnifi One soundbar speaker system to respond to your TV's remote. In addition, there are controls on the top-panel of the soundbar speaker.

Mounting Options: The soundbar speaker should be centered under or above your flat-panel TV screen. The lightweight easy-to-mount single speaker can be placed on a tabletop or wall-mounted. It can sit on a flat surface because of its integrated rubber feet that enable it to rest securely. If your TV is wall-mounted, the soundbar can be mounted right beneath it using the speaker's integrated keyhole slots (x2) on the rear-panel. The powered subwoofer receives its signal from the soundbar wirelessly, so it can be placed virtually anywhere in the room (up to 30' from soundbar). It only requires plugging into an AC outlet.
