Sony ULT Tower 7 Review: Powerful Party Sound With a 30-Hour Battery

Sony’s ULT party speaker lineup ranges from the relatively affordable $450 ULT Tower 5 to the frankly enormous $1,200 ULT Tower Max. Sitting between them, the Sony ULT Tower 7 delivers powerful sound, a wide selection of inputs, 420 watts of total output and a 30-hour battery.

However, this is still a gigantic party speaker. Although it is smaller than the Tower Max, the ULT Tower 7 weighs 50.3 pounds, making it difficult to carry by hand for long distances.

Professional inputs and support for up to 100 speakers

Many party speakers accept music from a DJ controller, but Sony goes further with RCA and balanced XLR inputs, along with an XLR output for expanding a wired setup. Its Auracast-based Party Chain feature lets you connect up to 100 compatible speakers—enough potential volume to take on Madison Square Garden.

Deep bass and room-filling 360-degree sound

The Sony ULT Tower 7 features an 11-inch woofer, two 4.7-inch midrange drivers and four tweeters. Two of the tweeters face the rear to help spread audio throughout the room.

The bass is deep and effective, with a physical impact that becomes especially noticeable at higher volume. It may not deliver quite the same shock at club-level volume, but its performance is still impressive.

A 360-degree driver configuration creates a wider soundstage and prevents the audio from feeling too confined. The bass remains fairly directional, but the speaker’s overall scale makes it easy to fill a room with sound.

Should you buy the Sony ULT Tower 7?

If you have the budget and space—and want to play loud all night—the Sony ULT Tower 7 is a strong choice. Its powerful bass, room-filling sound, flexible wired connections and 30-hour battery make it well suited to large parties.

The main drawback is portability. The built-in corner handles are usable, but you have to sharply tilt the speaker at awkward angles to attach the wheels. A retractable handle would make moving this 50.3-pound speaker much easier.
