These sit in different size classes, so this is not a straight ranking comparison. The Sony ULT Tower 5 ranks #5 of 40 party speakers by sound quality at $448; the Turtlebox Grande ranks #57 of 76 boombox speakers by sound quality at $730.
What the Sony ULT Tower 5 does well: At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. The tradeoff: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
What the Turtlebox Grande does well: 10-inch woofer. The tradeoff: They pretty much lie about all their specs and sound just okay in all youtube sound samples.
Buy the Sony ULT Tower 5 at $448 if you want a party speaker. Buy the Turtlebox Grande at $730 if you want a boombox speaker instead.
There is a real gap in water resistance: the Turtlebox Grande at IP67 (brief submersion) against the Sony ULT Tower 5, which has IPX4 (splashing).

The Two Speakers In Full
Sony ULT Tower 5: $448.00 Amazon eBay
Pros: At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. AudioTribe’s first impressions praise its deeper bass and clearer sound than the JBL PartyBox Club 120; it also has USB-C and USB-A, RCA, balanced XLR and mic inputs for DJ and karaoke use.
Cons: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance. Its single-woofer, two-tweeter layout lacks the Tower 7’s 360-degree rear-driver array, and the reviewer describes the sound assessment as first impressions rather than a controlled measurement comparison.

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.
