Short answer: the Zealot ZE41. It ranks #14 of 73 boombox speakers by sound quality at $289.90; the Sony ULT Field 7 ranks #40 and costs $400, which makes this an easy call rather than a real tradeoff.
What the Zealot ZE41 offers: The absolute best value for the bass performance, play time and max volume in the boombox class. Watch for: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.
What the Sony ULT Field 7 offers: Better sounding than the XG500 Watch for: Still not as deep bass as the top ranked speakers. 8khz peak
Buy the Zealot ZE41. It ranks higher for sound quality than the Sony ULT Field 7 and costs less, so there is no real case for the other one.
