Quality Stereo Speakers: The M20 bluetooth speakers provide immersive high-resolution stereo sound. Its decoupled 0.9" tweeters minimize internal vibrations, while the 4.9" mid/bass drivers and rear-firing reflex ports deliver sound with outstanding balance and drive. Bluetooth Speakers: Use Bluetooth 5.0 connectivity (with aptX, aptX HD, aptX Low Latency, SBC and AAC compatible) to wirelessly stream high resolution-quality audio (max 24-bit/48kHz) from your devices. There are also USB, digital optical, stereo RCA and 0.14" inputs, and a subwoofer output. P2P Braced Cabinets: The exceptionally rigid bluetooth bookshelf speakers' cabinets are supported with P2P bracing. This eliminates internal standing waves to improve the stereo image focus and sound-stage accuracy. The grille’s curved contours disperse tweeter activity, minimizing unwanted reflections. Great Sound Anywhere: Set the powered speaker as either the left or right channel for easy mains power access. Plus an EQ switch lets the system know if each bookshelf speaker is positioned in a corner, against a wall or in free space, so its digital sound processing can optimize the audio performance.
