M20 HD Wireless Music System: The Q Acoustics M20 is an active wireless music system designed to deliver powerful and immersive stereo sound for music, movies and gaming. The M20 consists of two stereo bookshelf speakers. One of the bookshelf speakers is self-powered with a built-in amplifier, as well as contains all of the system's analog and digital source inputs. The other bookshelf speaker is passive and connects to the powered bookshelf speaker via the included 13' length of speaker wire. Using a switch on the back panel of the powered speaker, you are able to designate the powered speaker as either the left or right channel.

Advanced Driver & Amplifier Design: Whether listening to music, watching a movie or playing a game, the M20's advanced driver technology is designed to produce accurate and highly immersive stereo sound wit low distortion. Powered by a built-in amplifier providing 128 watts of Class D amplification, each speaker receives 64 watts of power to its 2-way driver array (32 watts to each tweeter and 32 watts to each woofer).

• 0.875" Tweeter: Each speaker features a 0.875" dome tweeter that is decoupled to minimize any internal vibrations that can adversely affect the audio for crisp, clear highs that create a wide dispersion of stereo sound.
• 5" Woofer: Each speaker also houses a 5" cone mid/bass driver in a bass reflex enclosure with a rear-firing reflex port that combine to deliver well-balanced sound with detailed midrange and dynamic bass.

P2P (Point to Point) Cabinet Technology: Featuring award-winning cabinet technology, every element of the M20's enclosure design is specified to deliver an optimal audio performance. The beautifully sculpted cabinet uses Q Acoustics' proprietary P2P (Point to Point) bracing to support the parts of the enclosure that need to be stiffened. The result is an exceptionally rigid cabinet that eliminates internal standing waves to improve the focus of the stereo image and give the soundstage more accuracy than ever before. The grille's curved contours are also designed to disperse any tweeter activity, keeping unwanted reflections to a minimum (the grill is not removable).

Bluetooth 5.0: The Q Acoustic M20 HD wireless music system features built-in Bluetooth 5.0 with support for wireless audio streaming (A2DP) and control (AVRCP). You'll be able to wirelessly stream stored music, music apps, and other audio content from your Bluetooth-enabled smartphone, tablet, laptop, or desktop computer to the speaker system. You'll also be able to control basic playback functions (Play/Pause, Previous/Next Track, Volume Up/Down) from the included IR remote. You can pair multiple source devices with the speaker system, but only one device can be used at a time for playback. It will automatically connect with the last connected device when the system's Bluetooth input is selected. It supports a variety of Bluetooth audio codes including SBC (Sub-Band Coding), AAC (Advanced Audio Coding), aptX, aptX HD, and aptX LL (Low Latency) codecs.

• SBC: The SBC (Sub-Band Coding) is Bluetooth's standard audio codec that is universally compatible with all Bluetooth-enabled devices. SBC supports up to 320kbps.
• AAC: AAC (Advanced Audio Coding) is a step-up from Bluetooth's standard SBC codec and is Apple's standard audio code. AAC supports up to 250kbps.
• aptX: aptX is an audio codec that can provide "CD-quality" music (up to 16-bit/44.1kHz). The system will automatically utilize aptX when connected to a source (such as Android) that supports aptX.
• aptX HD: The Q Acoustics M20 also supports the higher resolution aptX HD for 24-bit/48kHz wireless audio. If your Bluetooth source device utilizes aptX HD then that resolution will be utilized automatically.
• aptX LL: In addition, the M20 features aptX LL (Low Latency) which automatically ensures a wireless Bluetooth connection can deliver sound in sync with visual media. It reduces delay and improves end-to-end speed of the audio transmission, resulting in a high quality, synchronized user experience with any transmitting device that supports aptX LL.

USB-B Port: The Q Acoustics M20 is equipped with a USB-B port for audio playback from your Windows PC (XP-up) or Mac computer (OS X). The speaker system supports playback of 2ch stereo PCM audio files, up to 24-bit/192kHz. A Windows PC will require the installation of a separate USB driver (click here). A Mac computer will not require the installation of a separate USB driver.

Optical Digital Input: The M20 HD wireless music system is outfitted with an optical (toslink) digital input that allows you to connect your TV. The optical digital output supports 2-channel PC audio up to 24-bit/192kHz. The optical digital input is not compatible with Dolby Digital, DTS, or other multichannel audio formats.

Dual Analog Inputs: The M20 is equipped with two line-level analog inputs. It has one stereo RCA input and one stereo minijack (3.5mm) input. Both analog inputs are on the rear-panel of the speaker system. It does not have a dedicated Phono input. If you want to connect a turntable, you will need an external phono preamp (sold separately - see Accessories Tab) or a turntable with a built-in phono preamp.

Binding Post Terminals: Binding post terminals are utilized to connect the included speaker wire between the powered and passive speaker. The passive speaker has a a binding post input to receive the audio signal from the powered speaker's binding post output. The speaker system comes with a 13' length of 16AWG speaker wire. However, you can replace the speaker wire with a higher quality and heavier gauge speaker wire. The binding posts will accept bare wire (up to 12AWG), pin-connectors, spade-lugs, and banana plugs (single only).

Subwoofer Output: The Q Acoustics M20 HD wireless music system is equipped with a mono-RCA subwoofer output for connection of a powered sub (sold separately) for bigger, deeper bass response. The M20's subwoofer output does not include a built-in low pass crossover frequency filter or level control. Make sure your powered subwoofer has a built-in low pass crossover and level control.

Simple Control: The Q Acoustics M20 HD wireless music system offers simple and convenient control. The powered speaker features top-panel controls that include Power On/Off and Volume Up/Down. The speaker system also comes with an IR remote control for wireless operation of basic functions such as Power On/Off, Source Input, Volume Up/Down, Mute, Play/Pause, and Previous/Next Track.

Mounting & Placement Options: The Q Acoustics M20 speakers can be mounted on stands (sold separately - see Accessories Tab), bookshelf, or other flat tabletop surface. The speakers should be placed 6.5' to 13' apart from one another, spaced 7.875" from the back wall, and positioned at ear level in a seated listening position for optimum performance. An EQ switch on the rear-panel of the powered speaker lets the system know if each speaker is positioned in a corner, against a wall, or in free space so its DSP (digital sound processing) can optimize the audio performance.

• Free Space: This EQ setting will give you the most bass output and is best suited when the speakers are placed away from the walls or corners.
• Against A Wall: This EQ setting will give you a mid-point in bass output and is best suited when the speakers are placed close to a wall or on a shelf.
• Corner Placement: This EQ setting will give you the least level of bass output and is best suited when the speakers are placed in corners of the room.

Power Requirements: The Q Acoustics M20 HD wireless music system requires connection to an AC power outlet. The use of surge protector or line conditioner (sold separately) is recommended. Only one of the speakers has to be plugged into an AC outlet and comes with a detachable 6' AC power cord (C7, 2-prong). The speaker system will automatically go into Standby mode when there is not audio signal or operation for approximately 20 minutes.
