Short answer: the Tribit Stormbox Blast 2 reaches deeper, while the Sony ULT Field 7 is the safer choice for listeners who want less aggressively bass-heavy sound. Tribit is 30 of 85; Sony is 52 of 85.
The Blast 2 delivers deep bass, but its boosted lower and upper bass, plus an elevated region around 6kHz, make it muddy. Its Xbass mode intensifies that problem, so more bass does not necessarily mean better balance.
The ULT Field 7 improves upon Sony’s XG500 and avoids the Blast 2’s particularly muddy tuning. It still lacks the deepest bass in its class and has a peak around 8kHz, so neither model is neutral by default.
Buy the Tribit Stormbox Blast 2 if maximum deep-bass impact matters more than a clean tonal balance.
Buy the Sony ULT Field 7 if you prefer a less bass-cluttered large portable speaker and can accept its treble peak.

The Two Speakers In Full
Tribit Stormbox Blast 2: $279.99 Amazon eBay
Older model: the Tribit Stormbox Blast (ranked higher, rated 4.5/5).
Pros: Pretty deep bass. Measured bass extension of 40Hz (-10dB).
Cons: Sounds quite muddy with the boosted lower and upper bass. Boosted treble around 6kHz. Xbass mode makes it sound even more muddy. Nowhere near as neutral and balanced as the first Blast and a big downgrade unless you only care about max volume

Sony ULT Field 7: $400 Amazon eBay
Older model: the Sony SRS-XG500 (ranked lower, rated 3/5).
Pros: Sony ULT Field 7 uses 2x 114mm x 114mm X-Balanced woofers + 2x 46mm (1.9”) tweeters. Its 6.3 kg, claimed 30 hours (Manufacturer specified) battery life, IP67 protection, aux input and stereo playback make it a practical option for its intended room or portable use. Measured bass extension of ~52Hz (-10dB).
Cons: Bass is limited by its ~52Hz specification. There is no companion app. A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
