JBL Boombox 3 vs onn Pro X Large Boom Boombox

Why pick the JBL Boombox 3: IP67 rated. The tradeoff: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.

The case for the onn Pro X Large Boom Boombox: High rated power for the price at 180W RMS (540W peak). The catch: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.

Buy the JBL Boombox 3. It is rated higher for sound quality, and saving $150.95 with the onn Pro X Large Boom Boombox does not make up for the sound-quality gap.
