These are not really the same size class, and that is the honest framing here. The Sony ULT Tower 7 ranks #1 of 40 party speakers by sound quality at $649.99; the Turtlebox Grande ranks #57 of 76 boombox speakers by sound quality at $730.
What the Sony ULT Tower 7 does well: A compelling large-party value at $650: 420W output, an IPX4-rated 30-hour battery, 360-degree sound, wheels and four carry handles at 22.8kg. Watch for: 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.
What the Turtlebox Grande does well: 10-inch woofer. Watch for: They pretty much lie about all their specs and sound just okay in all youtube sound samples.
Buy the Sony ULT Tower 7 ($649.99) for a party speaker; the Turtlebox Grande ($730) suits a boombox speaker instead.
If water resistance matters to you, the Turtlebox Grande at IP67 (brief submersion) holds up far better than the Sony ULT Tower 7 at IPX4 (splashing).

The Two Speakers In Full
Sony ULT Tower 7: $649.99 Amazon eBay
Pros: A compelling large-party value at $650: 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.

Turtlebox Grande: $730.00 Amazon eBay
Pros: 10-inch woofer. IP67 submersible shell with crush-proof ABS exterior. 158Wh battery provides ~3 days of playback. Bluetooth 5.4, party mode (100+ speakers). Measured bass extension of ~55Hz (-10dB).
Cons: They pretty much lie about all their specs and sound just okay in all youtube sound samples. Only 100w will never hit 126db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard. Barely any bass for a 10” woofer. Overpriced and not worth it.
