Sony ULT Tower 9 Overview

From huge holiday parties in the backyard, to quiet movie nights with the family, look to the ULT TOWER 9 Party Speaker from Sony. Packed inside its large frame, the ULT TOWER 9 offers nuanced, 360° room-filling sound from a pair of front and rear tweeters, front pair of midrange drivers, and a large X-Balanced woofer. Bass that can be ramped up for larger crowds with the press the ULT button and ULT DUCT baffle to help spread it around the room. Your music is enhanced by a synchronized 360° set of built-in party lights. You can stream tunes or play them from a USB stick or device, or you can create your own live music with optional mics and/or guitar. Wheeled for maximum portability, you can enjoy the ULT TOWER 9 at home or take the show on the road.
360 Degrees of Party Sound
In the ULT TOWER 9 is a pair of midrange drivers for vocal clarity, two front and two rear tweeters to fill the space, and a large X-Balanced woofer to bring the bass. Bass is so pronounced on the ULT TOWER 9 thanks to the X-Balanced woofer's nearly square design, which adds more surface area for increased sound pressure for deep bass with less distortion. Add in the ULT DUCT to spread bass around the space, plus a dedicated ULT button for a bass boost, and your guests will definitely feel the music.
Connect, Stream, or Play Live
You have a lot of options when it comes to the music you can play through your ULT TOWER 9. You can hook up traditional wired components using a single optical digital audio or 3.5mm AUX input. Play your digital library by plugging in an optional USB-A flash drive. One 1/4" mic input and one 1/4" mic/guitar combo input lets you add optional microphones and/or a guitar to show off your talents. However, when in doubt, stream your favorite playlists over Bluetooth from your mobile device of choice.

Pair your Bluetooth-enabled mobile device to stream audio through the ULT TOWER 9. With support for multipoint technology, you can simultaneously connect up to two devices at once. The speaker will automatically switch between devices as they play audio. This lets you share DJ duties or access a friend's playlist. If you have a Bluetooth Fast Pair-compatible Android device, you can pair to the speaker with just a tap.

360 Degrees of Party Lights
Create a club or festival vibe using the speakers built-in multi-colored lighting system. The lights are emitted from the top and bottom of the ULT TOWER 9, synchronizing to the beat of the music, and they're conveniently controlled using the Sound Connect mobile app.
Bigger Sound
For spaces too big even for the ULT TOWER 9, you can easily expand your coverage with additional speakers. Add just one additional ULT TOWER 9 via Bluetooth to double the sound and enjoy true stereo separation. You can also use the Party Connect function to add up to 100 more compatible speakers. Party Connect conveniently does not require an app to link speakers, just press the dedicated CONNECT button.
TV Sound Booster
Increase your TV's audio capabilities with TV Sound Booster. Connect the ULT TOWER 9 directly to your TV via the included optical audio cable, then activate TV Sound Booster in the Sound Connect mobile app.
Made to Move
Portability is an essential feature of the ULT TOWER 9. Easily physically move it from here to there with built-in dual casters and integrated carry handles on top of the speaker. Just tilt and roll. You're also not tied to a wall outlet for power. The built-in rechargeable battery gives you enough power for up to 25 hours of playback.

Sony ULT Tower 9 Reviews

Amazing Portable sound system

By Frank the audio guy
Rated 5 out of 5

As an Audio video technician by trade, I am very impressed by this speaker. The sound quality is amazing, and the sub can really move some air!! Build quality is very decent for a plastic enclosure but I would be very careful during transport. I have had mine only for a week, but I have been using it every day!!! I am sad to say that I have been neglecting my other gear in the house. I use it with line in for karaoke with a zoom vocal processor and wireless mics and an Ipad. I also make use of the bluetooth connectivity which links up seamlessly. Im on the fence about getting another for a pair!!!

Great product, highly recommend!

I have only bought Sony products over the years, they are always reliable and I have never been disappointed Sony never ceases to impress, unless space is an issue due to it being quite “bulky”, I highly recommend this product, I currently owned the Sony XP700 I’ve have had it for the past 2 years and loved it, But this Ult Tower 9 is on a whole other level! The bass is impressive “it will Definitely will shake the walls in your house” Mids and highs are very clear and pronounced at any volume & can handle any genre of music you throw at! And it sounds even better when paired with my XP700…… I highly recommend this product definitely worth the money!!
