Overview
Dynamic Bass Modes
Featuring a prominent ULT button, the SONY ULT 900 AC Bluetooth Party Speaker lets you switch between two powerful bass profiles. Moreover, ULT1 delivers deep, low-frequency resonance for immersive listening, while ULT2 provides punchier, high-energy bass, which is perfect for dancing and party vibes.
Instant Bass Control
With the touch of the ULT button on this party speaker, you can activate ULT1 or ULT2 bass modes based on your preference. So, whether you're after floor-shaking depth or a crisp, high-impact beat, the speaker adjusts instantly to match your party's energy.
Room-Filling Sound
Equipped with four tweeters, dual mid-range drivers, and a large X-Balanced Speaker Unit, this Bluetooth speaker projects 360-degree party sound across the space. Thus, whether you're near the speaker or at the back of the room, every guest enjoys clear vocals and powerful bass equally.
Deeper Bass with ULT DUCT
Integrated with a specially designed ULT DUCT, this speaker enhances bass output and ensures even distribution throughout the room. The advanced baffle system allows smooth, consistent bass flow, so you can feel the rhythm, not just hear it.
TV Sound Booster
Featuring Sony’s exclusive TV Sound Booster, this party speaker pairs seamlessly with your television to enhance both dialogue clarity and bass depth. With the X-Balanced Speaker Unit and rear-facing tweeters, it transforms regular TV sound into a room-filling, cinema-like experience.
Built-In Lighting and Karaoke Features
Designed to elevate celebrations, this SONY ULT 900 AC speaker includes customisable lighting effects and built-in karaoke functions. So, whether it’s a birthday, festival, or casual get-together, it brings interactive fun and visual appeal to every occasion.
