Feel the massive bass and stronger sound with the ULT TOWER 9 and ULT TOWER 9AC

The ULT TOWER 9 and ULT TOWER 9AC offers massive bass and powerful unrivalled sound pressure in the party speaker models. Users can take the party to every corner of the room with 360° Party Sound. The ULT TOWER 9 and ULT TOWER 9AC feature four tweeters that deliver clear sound to both the front and rear of the speaker, with two mid-range speakers for vocal clarity. The speaker also includes Sony’s X-Balanced Speaker Unit to ensure clear audio and powerful sound. Hitting the ULT button gives access to two exciting bass modes – ULT1 for deeper, lower frequency bass and ULT2 for powerful punchy bass. This speaker ensures the sound spreads regardless of where listeners are in the space and feel the full power of the music.

The party never has to stop thanks to the ULT TOWER 9’s up to 25-hour battery life1, while the ULT TOWER 9AC uses an AC connection without a built-in battery, delivering more powerful sound pressure. The easy-to-carry handle makes it simple to carry or lift and the stable castors help easily pull the speaker so listeners’ favorite tunes can follow wherever they go.

The ULT TOWER 9 and ULT TOWER 9AC do more than just play music — they transform a space into a full-on party experience. The 360° Party Lights create a synchronized lighting display2 that can link up to 100 compatible speakers, syncing both music and lighting seamlessly – filling any space with the ultimate party atmosphere.

The ULT TOWER 9 and ULT TOWER 9AC are also equipped with fun and convenient features, such as karaoke and guitar inputs, as well as the unique TV Sound Booster function that enhances the audio–visual sound experience, while watching everything from live performance videos to movies.
