Sony ULT TOWER 9AC Party Speaker

360 Degrees of Party Sound

In the ULT TOWER 9AC is a pair of midrange drivers for vocal clarity, two front and two rear tweeters to fill the space, and a large X-Balanced woofer to bring the bass. Bass is so pronounced on the ULT TOWER 9AC thanks to the X-Balanced woofer's nearly square design, which adds more surface area for increased sound pressure for deep bass with less distortion. Add in the ULT DUCT to spread bass around the space, plus a dedicated ULT button for a bass boost, and your guests will definitely feel the music.

Connect, Stream, or Play Live

You have a lot of options when it comes to the music you can play through your ULT TOWER 9AC. You can hook up traditional wired components using a single optical digital audio or 3.5mm AUX input. Play your digital library by plugging in an optional USB-A flash drive. One 1/4" mic input and one 1/4" mic/guitar combo input lets you add optional microphones and/or a guitar to show off your talents. However, when in doubt, stream your favorite playlists over Bluetooth from your mobile device of choice.

Pair your Bluetooth-enabled mobile device to stream audio through the ULT TOWER 9AC. With support for multipoint technology, you can simultaneously connect up to two devices at once. The speaker will automatically switch between devices as they play audio. This lets you share DJ duties or access a friend's playlist. If you have a Bluetooth Fast Pair-compatible Android device, you can pair to the speaker with just a tap.

360 Degrees of Party Lights

Create a club or festival vibe using the speakers built-in multi-colored lighting system. The lights are emitted from the top and bottom of the ULT TOWER 9AC, synchronizing to the beat of the music, and they're conveniently controlled using the Sound Connect mobile app.

Bigger Sound

For spaces too big even for the ULT TOWER 9AC, you can easily expand your coverage with additional speakers. Add just one additional ULT TOWER 9AC via Bluetooth to double the sound and enjoy true stereo separation. You can also use the Party Connect function to add up to 100 more compatible speakers. Party Connect conveniently does not require an app to link speakers, just press the dedicated CONNECT button.
