Short answer: the JBL Partybox Club 120. It ranks #6 of 53 party speakers by sound quality, rated 4.5/5, at $399.95; the Marshall Bromley 450 ranks #26, rated 3.7/5, and costs $569.99, so there is not much of a tradeoff to weigh.
RTINGS puts these in the same class and finds the Marshall Bromley 450 better balanced, with a more controlled bass that keeps vocals and instruments from getting muddy. Its tonal balance also stays the same all the way around the speaker, so guests hear the same thing wherever they are.
The JBL Partybox Club 120 is the better rated speaker overall and has the far more complete app, with custom EQ and light show control. In side by side sound samples, listeners often found the Marshall muffled next to a JBL Partybox, since JBL aims its sound forward with more treble.
RTINGS measured the longest battery life of the group on the Marshall, at nearly 19 hours. It also adds two XLR/6.35mm combo inputs and a swappable battery.
Buy the JBL Partybox Club 120. It is rated higher for sound quality than the Marshall Bromley 450 and costs less, which makes it the one to get unless you need something the other one does better.
