Benefits of Monitor Audio MASS Surround Sound 5.1 Ch Home Theater Speaker Package with Denon AVR-X250BT 5.1 Ch 4K Ultra HD AV Receiver:
Metal Matrix Polymer (MMP II) Mid/bass Driver with Soft Dome Tweeter

Whether listening to music, a game or a movie soundtrack, the MASS Satellite speaker has the talent to bring your audio to life. Thanks to the beautifully engineered integration of its two drivers, the MASS Satellite is an outstanding listen from the deepest bass notes to the crispest treble. Incredible dispersion and imaging put you in the centre of the action - and the satellite is as punchy and powerful, and as subtle and detailed, as you need it to be. Inside the cabinet, a Metal Matrix Polymer (MMP II) mid/bass driver and soft dome tweeter deliver outstanding full-range audio performance. Outside, a choice of luxurious cloth finishes, and integrated cable management, guarantee an attractive look in any environment.
Deep Bass Reproduction from a Compact Subwoofer

Designed to augment the deepest bass of Hollywood soundtracks, state-of-the-art games and music alike, the MASS Subwoofer delivers reinforced bass from its 203 mm long-throw driver powered by 120 watts of shove. It’s also compact enough to be discreetly positioned in a room. A sealed 15 mm MDF cabinet with 18 mm baffle, ample Class D amplification granting both strength and efficiency, and a big Metal Matrix Polymer (MMP II) driver make for deep, solid, rapid and well controlled low frequency presence. MASS Subwoofer digs deep and hits hard enough to make movies and music spring to life. And though compact enough to be stowed out of sight, the MASS Subwoofer looks and feels as good as its Satellite partners in its choice of smart cloth finishes.
MASS Movies

Hollywood knows its soundtracks are just as big a part of the cinema experience as its pictures – and, thanks to MASS, you can enjoy your own full-on home cinema surround sound experience without breaking the bank or compromising the look of your room. Despite its size, MASS is capable of dynamic, room-filling sound with all the punch and drive the biggest Hollywood blockbusters demand. With perfect clarity to build the tension in quieter scenes, hair-raising attack when the going gets explosive, and incredible effects placement to keep you at the heart of the story, MASS brings you the authentic cinema experience.
MASS Gaming

If you want to properly immerse yourself in your gaming experience, there’s no better way than MASS to put you right in the thick of the action. Gaming is hugely enhanced by accurate placement of effects, seamless panning right around the 360-degree soundfield and, thanks to the Subwoofer, incredible low-frequency presence. No matter if your favourite games rely on the roar of the crowd, the rattle of the guns or the tension-packed near-silence of a spooky alien planet, MASS gives you more of what you need. Enjoy every gaming scenario like never before and take your experience to an entirely different level.
MASS Music

Whether you like to listen in stereo or prefer a multi-channel mix, MASS has the talent to bring your favourite music to life. Thanks to the beautifully engineered integration between the Satellites and the Subwoofer, MASS is a thrilling listen from the deepest bass notes to the crispest treble. Incredible stereo imaging puts your favourite singer on the centre of the stage, while the combination of MMP II driver technology and soft dome tweeter in each Satellite gives each instrument extraordinarily faithful and convincing tonality. Fast, controlled and, above all, deep bass from the Subwoofer makes MASS as powerful and punchy a listen as it is subtle and detailed. It’s the speaker system your music has been waiting for.
