Sony ULT Tower 9AC

The Sony ULT Tower 9 combines a high-performance audio system with 7 speakers, 360° sound diffusion, synchronized light shows, and multiple features for karaoke and parties. With its 25-hour battery life and built-in wheels for mobility, it stands out as an all-in-one solution to liven up your events.

Sophisticated Sound Architecture

The ULT Tower 9 stands out for its advanced audio architecture, featuring a large 32 cm X-Balanced woofer for deep bass, two 12 cm midrange speakers ensuring optimal vocal clarity, and four strategically positioned tweeters—two at the front (5 cm) and two at the rear (4 cm).

This setup enables true 360° sound diffusion, projecting even sound in all directions throughout the room. The rear tweeters, often missing from competing speakers, allow people behind the device to enjoy audio quality similar to those in front.

The ULT button, a signature of this range, offers two distinct modes: ULT1 for deeper bass and ULT2 for punchier sound. This feature makes it easy to tailor the sound signature to the desired atmosphere or the music style being played.

Complete Party Features

Sony has integrated a 360° lighting system that syncs with the music, creating a festival-like atmosphere in your living room. These light shows are fully customizable via the dedicated app, allowing you to adapt the visual mood to any occasion.

For karaoke fans and musicians, the ULT Tower 9 features dedicated microphone and guitar inputs, turning the speaker into a true compact PA system. The control panel includes specific settings for echo and tone, letting you optimize your vocal performance. The speaker is compatible with Sony ULTMIC1 wireless microphones (sold separately), which provide valuable freedom of movement during karaoke sessions.

The Party Connect function lets you sync up to 100 compatible speakers to amplify the sound and visual experience at large events. You can also pair two ULT Tower 9 units in stereo mode for more precise sound spatialization.

Advanced Connectivity and Versatility

The ULT Tower 9 shines with its versatile connectivity. It features Bluetooth 5.3 with support for SBC, AAC, and LDAC codecs—the latter enabling high-definition audio transmission up to 24-bit/96 kHz. The multipoint function allows two Bluetooth devices to connect simultaneously, making it easy to share playlists among friends.

Fast Pair technology simplifies pairing with Android devices—just bring your smartphone close to the speaker. For other sources, the ULT Tower 9 offers a 3.5 mm mini-jack input, a USB-A port for audio file playback and device charging, as well as an optical input.

The latter, combined with the TV Sound Booster function, turns the speaker into an effective audio companion for your TV, especially when watching concerts or movies. The Sony Sound Connect app lets you optimize settings for this specific use, bridging the gap between home theater and party speaker.

Remarkable Battery Life and Smart Management

With its 25-hour battery life, the ULT Tower 9 keeps your parties going without interruption. The fast-charging feature is particularly impressive: just 10 minutes of charging gives you 3 hours of use—ideal if you forget to recharge.

Sony has integrated Battery Care technology to prevent battery overcharging, thus extending its lifespan. The app also lets you monitor the charge level in real time, avoiding unpleasant surprises.

The powered USB-A port turns the speaker into a power bank, allowing you to charge a smartphone during the party—a handy feature that keeps your guests from running out of battery mid-celebration.

Dedicated App and Intuitive Control

The Sony Sound Connect app offers an intuitive interface to personalize your experience. You can adjust the 10-band equalizer to fine-tune the sound signature to your preferences or music style.

The light shows can be precisely controlled via the app, letting you choose from different modes or create your own lighting sequences. The app also keeps a history of your recent listens, making it easy to find your favorite tracks.

For TV use, the app offers specific settings that optimize sound when watching audiovisual content. These tailored presets make it easy to switch from party mode to a home theater setup.

Clever Design and Portability

The ULT Tower 9 features a bold vertical design that’s thoughtfully engineered for mobility. Despite its substantial size, Sony has included an ergonomic handle and sturdy swivel wheels, making it easy to move from room to room. The illuminated touch panel on top provides intuitive access to controls and is splash-resistant—a reassuring feature for lively parties.

The design takes practical constraints into account: the control panel, located on top, remains accessible even in tight spaces and lets you easily adjust volume, lighting modes, or karaoke settings without interrupting the fun.
