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 Zealot ZE41 ranks #17 of 113 boombox speakers by sound quality at $219.95.
Different sizes. The ULT Tower 7 is a 50.3 lbs (22.8 kg) party speaker. The ZE41 is an 25.4 lbs (11.5 kg) boombox. Each is rated within its own class.
The ZE41 is the best value in its class for bass, playtime and volume, but it is rolled off up top and not very balanced. Its claimed battery is only 4 hours.
The ULT Tower 7 has punchy, clean ULT1 bass, 360-degree sound and a claimed 30 hours with the lights off.
Buy the Sony ULT Tower 7 at $648 for a party speaker, or the Zealot ZE41 at $219.95 for a boombox speaker instead.
