Sony has unveiled three new models in its ULT Power Sound line of high-performance party speakers: the ULT Tower 5, ULT Tower 7, and ULT Tower Max. These models continue the legacy of the ULT Power Sound series while introducing subtle design updates. The speakers emphasize sound quality, with features such as 360° sound dispersion, power outputs up to 2150 W (on the ULT Tower Max), automatic frequency adjustment, and an improved RGB LED lighting system. Connectivity options are comprehensive, including Bluetooth 5.3, RCA ports, XLR inputs and outputs for linking multiple speakers, and a microphone/instrument jack. They also support advanced audio codecs like LDAC and offer features such as stereo pairing and multi-speaker synchronization through the Auracast standard, though it is unclear if these are proprietary or open-source. Each model has a slightly rounded rectangular shape with matte black covers and an RGB lighting system that matches the internal structure. The ULT Tower 5 and 7 include a carrying handle, while the larger ULT Tower Max and Tower 7 also feature wheels for easier transport. All three models include new sound modes, such as ULT 1 and ULT 2, which enhance bass in different ways, along with a Flat mode for a more balanced sound and a 10-band equalizer. An additional feature, the ULT Duct, improves bass reproduction by optimizing the bass reflex design, which enhances the delivery of low frequencies. The smallest model, the ULT Tower 5, is IPX4 certified for splash resistance and measures 358 x 534 x 280 mm, weighing 12.7 kg. It includes a single 230 mm woofer and two 60 mm tweeters, delivering 300 W of power. It runs on a battery, offering up to 20 hours of playback. The intermediate model, ULT Tower 7, is also IPX4 certified and larger, with dimensions of 421 x 710 x 347 mm and a weight of 22.8 kg. It features a more complex audio setup, including a 280 mm woofer, a 120 mm midrange speaker, and four 50 mm tweeters, providing 360° sound dispersion and 420 W of power. It can also run on battery for up to 30 hours. The flagship model, ULT Tower Max, is the largest and most powerful, measuring 534 x 1062 x 472 mm and weighing 56.3 kg. It lacks IP certification and is designed for use with mains power only. The speaker features two front and one rear 280 mm woofer, two 120 mm midrange speakers, and multiple tweeters and broadband speakers, delivering an impressive 2150 W of power. All three models are now available for purchase, with prices set at 400 euros for the ULT Tower 5, 600 euros for the ULT Tower 7, and 1500 euros for the ULT Tower Max.
