These sit in different size classes, so this is not a straight ranking comparison. The Teufel Rockster Air 2 ranks #5 of 14 battery-powered PA speakers by sound quality at $499.99; the Marshall Bromley 450 ranks #23 of 42 party speakers by sound quality at $649.95.
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 ($649.95) 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.

The Two Speakers In Full
Teufel Rockster Air 2: $499.99 Amazon eBay
Older model: the Teufel Rockster Air (ranked lower, rated 3.4/5).
Pros: More consistent off-axis sound than the JBL Partybox 130, thanks to its single horn-loaded compression driver. Projects sound more evenly to the sides, unlike the JBL’s narrower front-firing dispersion. Cleaner instrument separation at high volume than the JBL Partybox 130, which turns anemic and loses bass at max volume despite its bass boost.
Cons: Bass isn’t as deep as the JBL Partybox 130’s boosted bass, though the JBL’s is boomy rather than truly deep. Bass and treble aren’t perfectly controlled at maximum volume - can sound hollow or too bright unless turned down from default. Not meaningfully louder than its 3-year-old predecessor, and the reviewer found the overall tuning a bit worse.

Marshall Bromley 450: $649.95 Amazon B&H Photo Video eBay
Pros: A balanced, warm sound with a flat midrange that keeps vocals and instruments clear, plenty of bass rumble and enough treble for energetic vocals, per RTINGS’ lab tests. Drivers on all four sides keep the tonal balance nearly the same from any angle, and M1M Tech Channel found it more open and airy than the Soundboks Mix and Teufel Rockster Air 2, with deeper bass than both. RTINGS measured 18.8 hours of battery from a swappable LiFePO4 pack shared with the Bromley 750, and it adds IP55 protection, two XLR/6.35mm combo inputs, USB-C audio, Auracast and physical bass and treble knobs.
Cons: 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. The warm tuning lacks some fine treble detail. There is no graphic EQ, only bass and treble knobs, and its stereo spreads left and right channels around the cabinet, so panned elements can land on the wrong side. At 12.3 kg it has a carry handle but no wheels.
