These sit in different size classes, so this is not a straight ranking comparison. The Teufel Rockster Air 2 ranks #5 of 17 battery-powered PA speakers by sound quality at $499.99; the Marshall Bromley 450 ranks #26 of 53 party speakers by sound quality at $569.99.
In M1M Tech Channel’s side by side test the Marshall Bromley 450 went deeper, bringing real low bass as well as kick drum punch, which the reviewer found missing from the Teufel Rockster Air 2. The Marshall’s drivers on every side also made it sound more open and spacious.
The Teufel plays louder, and the Marshall’s warm, soft tuning gives up some fine treble detail. At max volume the Bromley 450 also gets less composed, according to HeadphoneCheck.
The Marshall has two XLR/6.35mm combo inputs, a swappable battery, IP55 protection and a claimed 40+ hours of battery.
Buy the Teufel Rockster Air 2 ($499.99) for a battery-powered PA speaker; the Marshall Bromley 450 ($569.99) suits a party speaker instead.
If water resistance matters to you, the Marshall Bromley 450 at IP55 (water jets) holds up far better than the Teufel Rockster Air 2 at no water resistance.
