Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 7 ranks #1 of 39 party speakers by sound quality at $649.99; the Soundboks 2 ranks #8 of 14 battery-powered PA speakers by sound quality at $449.

This pits Sony’s Tower 7, a 360-degree consumer party speaker, against the Soundboks 2, a performer-focused battery PA. The Tower 7 offers seven drivers for 360-degree sound, a claimed 30-hour battery, wheels, IPX4 splash resistance, 10-band EQ and a full RCA/XLR/USB-C/mic input section. The Soundboks 2 offers dual 10-inch woofers rated to 124dB max SPL and a removable 40-hour battery, though it is a discontinued model without app EQ or TWS pairing.
Choose the Tower 7 for wheels for easier transport and immersive 360-degree party sound: Its wheels also make it easier to roll between rooms or events. Its 360-degree drivers and ULT1/ULT2/EQ modes suit a living-room-to-backyard party speaker better than a performer-focused PA cabinet.
Choose the Soundboks 2 for higher peak output at a lower price, discontinued caveats aside: Its claimed 40h battery beats the Tower 7’s 30h. At $449 it also costs less. It is discontinued, so check current stock and condition before buying.
Buy the Sony ULT Tower 7 at $649.99 if you want a party speaker. Buy the Soundboks 2 at $449 if you want a battery-powered PA speaker instead.
Water resistance is not close: the Sony ULT Tower 7 is rated at IPX4 (splashing), well ahead of the Soundboks 2 at no water resistance.

The Two Speakers In Full
Sony ULT Tower 7: $649.99 Amazon eBay
Pros: A compelling large-party value at $649.99: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 22.8kg. The full review praises its punchy, clean ULT1 bass, ULT2’s higher-output mode, simplified controls and unusually complete I/O: USB-C, USB-A, RCA, balanced XLR and mic input.
Cons: The reviewer notes that Auracast pairing is not backward-compatible with Sony’s older Party Connect speakers, and the hard-plastic corners lack protective rubber bumpers. IPX4 is splash resistance rather than full weatherproofing; the 30-hour claim requires lights off.

Soundboks 2: $449.00 Discontinued eBay
Pros: Built for maximum outdoor output: its two 10-inch woofers and silk-dome tweeter reach a claimed 124dB, while the removable battery is rated for up to 40 hours. It also provides aux, microphone and guitar inputs, making it a practical battery-powered option for loud parties and informal performances.
Cons: At 15kg it is large to transport, lacks weather protection, app EQ and TWS stereo pairing, and relies on an external charging arrangement. Its tonal balance and bass depth are less refined than stronger modern party speakers, and this discontinued model requires caution around used-battery condition and support. Discontinued.
