Short answer: the Zealot ZE41 for bass, play time and volume per dollar, if you can lift it. It is the absolute best value for bass performance, play time and max volume in the boombox class, but it is also the heaviest and biggest boombox around. The Middleton reaches very deep bass for its size and weight, though a 5db dip at 1.7kHz and 6.3kHz keeps its response uneven.
The case for the Marshall Middleton: Very deep bass for the size/weight. The tradeoff: 5db dip at 1.7kHz and 6.3kHz.
What the Zealot ZE41 gets right: The absolute best value for the bass performance, play time and max volume in the boombox class. The catch: The heaviest and biggest boombox speaker around.
Buy the Marshall Middleton ($217.89) for a large speaker; the Zealot ZE41 ($259.90) suits a boombox speaker instead.
There is a real battery-life gap here: the Marshall Middleton is rated for 20 hours, the Zealot ZE41 only 4 hours.

The Two Speakers In Full
Marshall Middleton: $217.89 Amazon eBay
Pros: Very deep bass for the size/weight. Measured bass extension of 39Hz (-10dB).
Cons: 5db dip at 1.7kHz and 6.3kHz. 9kHz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.

Zealot ZE41: $259.90 Amazon Aliexpress eBay
Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: 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.
