The Sony ULT TOWER 9 SRS-ULT900AC is a tower-style Bluetooth party speaker built for music, karaoke and home entertainment. Its ULT POWER SOUND system offers two bass modes, ULT1 and ULT2, while the combination of a large woofer, midrange units and front and rear tweeters creates a wide sound presentation.
The speaker combines powerful audio with party-focused features including 360° Party Sound, party lighting, karaoke functionality and a 10-band custom EQ. Its TV Sound Booster and optical input also allow it to be used for enhanced TV audio, extending its use beyond music playback.
Built for convenient movement, the ULT TOWER 9AC features an integrated handle and castors. Bluetooth 5.3, LDAC support, Party Connect, Stereo Pair, USB smartphone power output and dedicated microphone/guitar inputs provide flexibility for everyday entertainment and larger gatherings.
Key Features
ULT POWER SOUND with Two Bass Modes
Different music can call for different levels of bass impact. ULT POWER SOUND provides two dedicated modes, ULT1 and ULT2, allowing you to switch between two bass-focused sound profiles directly from the speaker.
360° Party Sound
When people are positioned around a room, conventional directional sound can leave some listeners with a less consistent experience. 360° Party Sound helps distribute the audio more widely around the speaker for group listening and party environments.
520W Power Output
The SRS-ULT900AC is specified with a 520W power output, giving the speaker substantial audio output for party and entertainment use. The tower configuration combines its woofer, midrange units and tweeters into a single speaker system.
360° Party Lights
Music-focused gatherings benefit from more than audio alone. The integrated 360° Party Lights add visual effects around the speaker and can be controlled through the compatible Sony app.
TV Sound Booster
TV viewing can benefit from a more substantial speaker system than the television's built-in audio. TV Sound Booster works with the speaker's optical input to enhance compatible TV audio.
Karaoke and Guitar Inputs
The SRS-ULT900AC includes dedicated microphone and guitar/microphone inputs, allowing it to be used for karaoke or as an amplifier for guitar performance.
10-Band Custom EQ
Different listeners have different preferences for bass, vocals and treble. The 10-band custom EQ gives you detailed control over the sound profile for a more personalized listening experience.
Bluetooth 5.3 with LDAC
Wireless playback is supported through Bluetooth 5.3, with SBC, AAC and LDAC codecs supported. This allows compatible smartphones and other Bluetooth devices to stream audio wirelessly.
Party Connect and Stereo Pair
The speaker supports Party Connect and Stereo Pair functions with compatible Sony speakers. This provides additional options for expanding the listening setup when supported devices are available.
USB Smartphone Power Output
Long entertainment sessions can also drain a smartphone battery. The built-in USB power port can provide power to a compatible smartphone while the speaker remains in use.
Easy Movement with Handle and Castors
A tower speaker can be difficult to reposition without dedicated mobility features. The integrated handle and castors make it easier to move the SRS-ULT900AC between suitable locations.
Splashproof Top Surface
The top surface of the speaker is specified as splashproof. This provides added protection against splashes, while the product should still be kept away from situations involving significant water exposure.
