If your current Bluetooth speaker disappears the second people start talking, this is the kind of upgrade that changes the whole vibe. The Sony ULT Tower 9 (SRSULT900) is a full-size wireless party speaker built for big, room-filling sound, deep bass, and all the lights-and-effects drama you’d expect at this price. With the current deal dropping it to $699, about 22% off, it finally feels like something you can justify for parties, backyard hangs, and even day-to-day listening.
What you’re getting
This is not a bookshelf speaker that happens to be loud. The ULT Tower 9 is a tall, floor-standing unit with multiple drivers, serious low-end, and a design built to project sound across a big space. It’s meant for living rooms, basements, rec rooms, and open-plan areas where you actually want to feel the music, not just hear it in the background.
You’re getting wireless connectivity, so it works like a normal Bluetooth speaker for phones, tablets, and TVs, plus physical inputs for more permanent setups. As a party speaker, it leans into the experience: built-in lighting effects, punchy bass, and tuning that makes playlists, DJ mixes, and concert videos feel more alive. It’s the kind of setup you can roll out for a party and leave in place as your main music system the rest of the time.
Why it’s worth it
At full price, the ULT Tower 9 sits in “statement piece” territory. At $699, it becomes a lot more attractive if you host often, have a big space to fill, or want one speaker that can handle everything from background music to full-on party mode. You’re getting the scale and presence of a small PA system without needing to learn mixer menus or deal with pro-audio gear.
Because it’s wireless and self-contained, setup is easy: plug it in, pair your phone, and you’re done. No amps, no receivers, no separate subwoofers or satellites to hide. If you already live inside the Sony ecosystem, it’s even easier to integrate with other gear, but it works just fine as a standalone centerpiece too.
The bottom line
If you’ve been wanting a proper party-ready system that actually feels like an upgrade from a soundbar or portable speaker, this Sony ULT Tower 9 at $699 is worth a serious look. You’re getting big, room-filling sound, party-friendly features, and a genuine centerpiece speaker for roughly $200 off the regular price.
