Short answer: the Onn Large Party gen 2. It ranks #17 of 54 party speakers by sound quality, rated 3.9/5, at $129; the Marshall Bromley 450 ranks #26, rated 3.7/5, and costs $569.99, so there is not much of a tradeoff to weigh.
The Onn Large Party gen 2 is the lighter pick. A budget party speaker on wheels with real bass impact, karaoke inputs and an FM radio. At 20.9 lbs (9.5 kg) it weighs noticeably less than the Marshall Bromley 450 at 27.1 lbs (12.3 kg). Watch for: The low price shows in the refinement.
The Marshall Bromley 450 is the longer-running option. A rugged, weather resistant party speaker with drivers on every side, a swappable battery, and mic and guitar inputs. It is rated for 40 hours of battery against 12 for the Onn Large Party gen 2. It supports AAC Bluetooth, which the Onn Large Party gen 2 lacks. It has an adjustable EQ, which the Onn Large Party gen 2 lacks. The tradeoff: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed.
Buy the Onn Large Party gen 2. It is rated higher for sound quality than the Marshall Bromley 450 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
