These are not really the same size class, and that is the honest framing here. The Sony ULT Tower 7 ranks #1 of 53 party speakers by sound quality at $648; the Tribit Stormbox Blast 2 ranks #31 of 113 boombox speakers by sound quality at $279.99.
What the Sony ULT Tower 7 does well: A big, loud party speaker on wheels with punchy bass, a 30 hour battery, 360 degree sound and inputs for mics and instruments. It supports LDAC Bluetooth, which the Tribit Stormbox Blast 2 lacks. It links with other speakers (Auracast), which the Tribit Stormbox Blast 2 cannot. 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.
The Tribit Stormbox Blast 2 is the lighter, tougher choice. A big, waterproof party speaker with deep bass, very high volume, a 30 hour battery and two mic inputs. At 19.2 lbs (8.7 kg) it weighs much less than the Sony ULT Tower 7 at 50.3 lbs (22.8 kg). It is rated IP67 against IPX4 for the Sony ULT Tower 7. The tradeoff: Sounds quite muddy with the boosted lower and upper bass.
Buy the Sony ULT Tower 7 ($648) for a party speaker; the Tribit Stormbox Blast 2 ($279.99) suits a boombox speaker instead.
