These sit in different size classes, so this is not a straight ranking comparison. The Soundboks Rider ranks #26 of 43 party speakers by sound quality at $599; the Sony ULT Field 7 ranks #52 of 85 boombox speakers by sound quality at $400.
What the Soundboks Rider does well: At 6.5 kg it is the lightest Soundboks yet, with a carry handle, IP66 dust and water protection, and the same swappable 100Wh battery as the Mix and Soundboks 4, rated for 35 hours at mid volume and 8 hours at maximum. The tradeoff: Its sealed 8in woofer runs out of real bass at high volume: Xander measured the -6 dB point rising to roughly 75 to 85 Hz at maximum, with 40 Hz some 20 dB down, and M1M heard the bass pulled back toward the upper bass above mid volume.
The case for the Sony ULT Field 7: Sony ULT Field 7 uses 2x 114mm x 114mm X-Balanced woofers + 2x 46mm (1.9”) tweeters. Watch for: Bass is limited by its ~52Hz specification.
Buy the Soundboks Rider at $599 if you want a party speaker. Buy the Sony ULT Field 7 at $400 if you want a boombox speaker instead.

The Two Speakers In Full
Soundboks Rider: $599.00 Amazon eBay
Pros: At 6.5 kg it is the lightest Soundboks yet, with a carry handle, IP66 dust and water protection, and the same swappable 100Wh battery as the Mix and Soundboks 4, rated for 35 hours at mid volume and 8 hours at maximum. Xander’s measurements found its flat profile genuinely flat, with distortion around 0.2 percent at moderate volume and below 2 percent from 500 Hz to 10 kHz even at full output, and the Indoor profile reaching down to 40 Hz at moderate volume. Both Xander and M1M Tech Channel preferred its punchy, controlled kick bass to the larger Soundboks Mix, and the app adds a six-band EQ with saveable presets.
Cons: Its sealed 8in woofer runs out of real bass at high volume: Xander measured the -6 dB point rising to roughly 75 to 85 Hz at maximum, with 40 Hz some 20 dB down, and M1M heard the bass pulled back toward the upper bass above mid volume. It measured 107 dB(C) outdoors for Xander and 113.2 dB(C) for M1M, about 3 dB below the Soundboks Mix and well short of the claimed 118 dB. There is no TeamUp, so it cannot link with other Soundboks speakers, the strap and charger are sold separately, and Xander found the grille causes dispersion artifacts around 5 kHz and judged the price too high for what it delivers.

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.
