Engineered to make hearts tremble
The 320 mm x 320 mm X-Balanced Speaker Unit uses an almost-square diaphragm for greater surface area and sound pressure, while the ULT DUCT baffle extends bass smoothly through the room. Choose ULT1 for deep, low-frequency rumble or ULT2 for punchy impact, then sculpt it all with the 10-band EQ.

Frequently asked questions
What are the ULT1 and ULT2 bass modes?
Press the ULT button to choose ULT1 for deeper, lower-frequency bass or ULT2 for powerful, punchy bass — two distinct moods for the same massive low end.
Does it come with karaoke microphones?
Mic and guitar inputs with echo and key controls are built in; the ULT MIC wireless karaoke mic pair is an optional accessory sold separately.
How does 360° Party Sound work?
Four tweeters fire front and rear, two mid-range drivers handle vocal clarity, and the large 320 mm x 320 mm X-Balanced woofer with ULT DUCT spreads deep bass to every corner of the room.
Can it improve my TV's sound?
Yes. Connect it to your TV with the supplied optical cable and enable TV Sound Booster in the Sony Sound Connect app for enhanced audio-visual sound.
Can I link more speakers?
Party Connect syncs music and lighting across up to 100 compatible speakers with a dedicated CONNECT button — no app required — or pair two ULT TOWER 9ACs for true stereo.
Is it easy to move around?
A built-in handle and stable castors let you pull it over long distances, and the splash-resistant top panel means spills won't stop the party.
How do I fine-tune the sound?
A 10-band equalizer lets you hear music exactly as you like it, with Sound Field Optimization automatically adjusting for surrounding noise.
