With the huge front-facing X-Balanced Speaker Unit for increased sound pressure and minimised distortion, plus 2 mid-range and 4 tweeters for remarkable clarity and detail, you'll hear great 360° party sound anywhere in the room.
For sound personalisation, the Sony | Sound Connect app offers an intuitive 10-band equaliser and multiple presets.
Unleash two additional sound modes with the ULT button. Deep Bass boosts the low frequencies and enriches the music with resonant bass. Attack Bass amplifies the sound pressure even further and creates unrivalled power and energy.
Multiple LEDs at the top and bottom of the ULT TOWER 9 synchronise with the music for a stimulating 360° party light show. The colours and lighting can be adjusted in the app.
With two solid wheels and a handle, this portable speaker can be tilted and then pulled or pushed for easy movement around the venue and transport from one location to another.
Thanks to sound field optimisation, the sound is always clear, even in noisy environments.
Apart from music playback, the ULT TOWER 9 can be connected to almost any TV for a cinema-like sound experience. Simply connect the supplied optical cable and use the TV Sound Booster button to bring your favourite series and films to life.
The speaker includes two microphone inputs. You can even connect a guitar and use the ULT TOWER 9 as a portable guitar amplifier.
The speaker is easy to operate using the buttons on the top of the device or via the Sony | Sound Connect app.
And for an even greater sound experience, use Party Connect to connect up to 100 compatible Sony speakers via Bluetooth. If you have another ULT TOWER 9, you can pair them with Stereo Pair to create a powerful stereo system.

Source: Digitec GalaxusSony does not achieve a second test victory. The ULT Tower 9AC offers very simple operation and powerful sound. The many connections, including an optical digital input, are also pleasing. However, the Sony needs a fixed place near a power socket, and even the castors only make the almost 30 kg party tower mobile to a limited extent.
