In the world of party speakers, sheer volume often trumps sonic fidelity. Sony’s new ULT Tower 10 aims to challenge that notion, promising not just room-shaking power but also a surprisingly nuanced audio experience. This isn’t just another big box with flashing lights; it’s a statement piece for those who take their gatherings seriously.
The ULT Tower 10 is an absolute monolith, and there’s no getting around its physical presence. Standing nearly four feet tall and weighing over 60 pounds, its “portability” is entirely dependent on the built-in handle and sturdy wheels, which thankfully make moving it across a patio or living room manageable. The build quality is excellent, with a robust cabinet and a metal grille that feels ready to withstand the rigors of a lively party. Its design is purposeful, with drivers angled upwards and outwards to achieve what Sony calls 360° Party Sound. The integrated light show syncs with the music, creating dynamic, floor-to-ceiling effects that genuinely enhance the atmosphere, moving well beyond the simple pulsing LED rings seen on lesser speakers.

At the heart of the ULT Tower 10’s performance is the prominent “ULT” button, which cycles between two levels of bass enhancement. The first level, ULT1, delivers a deep, resonant bass that adds significant weight and punch to tracks without completely overwhelming the mix. This is the sweet spot for most listening. Engaging ULT2, however, is like unleashing a seismic event. The low-end pressure becomes immense, creating a physical, club-like experience that you can feel in your chest. While impressive, it can muddy the midrange on complex tracks, but for genres like EDM, hip-hop, or dance music, it’s undeniably thrilling. Critically, even with the bass boosts off, the speaker provides a balanced and powerful sound that fills large spaces effortlessly, a testament to the quality of its X-Balanced speaker units.
Beyond its audio prowess, the ULT Tower 10 is a comprehensive entertainment system. It ships with a dedicated wireless microphone, making it an instant karaoke machine right out of the box. The mic quality is surprisingly clear, with minimal latency and dedicated echo and key controls on the speaker’s top panel. A second microphone or a guitar can be plugged into a separate input, complete with its own gain knob. Connectivity is robust, with Bluetooth 5.2 supporting both SBC and AAC codecs, a USB-A port for playing files and charging devices, and an optical-in for connecting to a TV to create a massive soundbar. The Party Connect feature allows you to link up to 100 compatible Sony speakers, transforming a party into a full-blown festival. While its IPX4 rating only protects against light splashes, it’s enough peace of mind for poolside use.
The ULT Tower 10 is not for everyone, and its value is defined by its purpose. If you’re looking for a casual Bluetooth speaker, this is overkill. But for the dedicated party host, aspiring DJ, or karaoke enthusiast, it presents a compelling all-in-one package. It replaces the need for separate PA systems, lighting rigs, and karaoke setups. While the price is steep, it consolidates the cost and complexity of multiple devices into one powerful, well-designed unit. It’s an investment in creating memorable events, delivering an audio-visual experience that few competitors can match in a single chassis.
