Big Sound, Compact Design

This speaker delivers room-filling performance with an ortho-directional design and a flow-optimized bass reflex duct. Despite its compact footprint, it produces deep bass and crystal-clear highs for a natural, balanced sound.

 

Precision Audio Performance

With a wide frequency range of 28–20,000 Hz (-3 dB), you’ll hear every detail from the lowest notes to the brightest treble. The high-efficiency ferrofluid-cooled neodymium tweeter ensures crisp clarity, while the 6.5" long-throw pulp cone woofer delivers powerful, controlled bass.

 

Crafted for Quality

Built from high-density fiberboard, reinforced plastic, and a woven steel mesh grille, this speaker combines durability with refined acoustic engineering. The solid construction minimizes resonance for pure sound reproduction.

 

Powerful and Efficient

The built-in 100 W ultra high-efficiency amplifier provides strong, distortion-free output, perfect for both casual listening and high-volume sessions.

 

Wireless Freedom

Stream music your way with beam-forming Wi-Fi technology and Bluetooth 4.0 LE. Enjoy seamless access to your favorite services including AirPlay 2, Spotify Connect, and Bluetooth audio.

 

Flexible Connections

Easily integrate with your setup using the 3.5 mm audio input or PCM optical input. Simple, intuitive controls include plus/minus buttons, a function button, stereo selector switch, and an RGB LED display.

 

Universal Power Supply

Ready for global use, the speaker features a universal power supply (AC 100–240 V, 50–60 Hz), making it just as reliable on the road as it is at home.
