Marshall Middleton vs onn Portable FM Boombox

What the Marshall Middleton offers: Very deep bass for the size/weight. Watch for: 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.

What the onn Portable FM Boombox offers: Extremely good value. Reasonably deep bass, though not as deep as something like the JBL Xtreme 3, Soundcore Boom 2, or Tribit Stormbox Lava. IPX7 waterproof and floats. FM radio with 10 presets. 6 multicolor LED lighting effects. Can run on battery or corded power. Watch for: Reasonable frequency response, but not quite as smooth as some of the top-ranked speakers in this size. No custom EQ. Only available in the United States and Canada.
