The Two Speakers In Full
Zealot S95: $157.41 Amazon AliExpress eBay
Pros: A good value for the boombox class. Appears to be the same internals as the ZE01. Bigger case and goes deeper than the ZE01. Measured bass extension of 45Hz (-10dB).
Cons: A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers.

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.
