Short answer: the Stormbox Blast for most people - it punches above its size and costs a fraction of the price; the Rockster Air 2 if you need more raw output and real instrument/mic inputs. These rank #5 and #2 out of 17 party-size speakers, at $499.99 and $199.99, with the Rockster Air 2 costing $300 more.
The Stormbox Blast is the value story here. At 5.45 kg (12 lbs) and $199.99, our own notes rate it as genuinely competitive with speakers in this party-size class, with bass depth approaching some entry-level JBL Partybox models once EQ’d - and it holds an IPX7 rating the Rockster Air 2 doesn’t have at all.
The Rockster Air 2 wins on scale and connectivity, not value. Its 80W output and larger 10” woofer are built to fill more space than the Stormbox Blast’s compact 4”-class drivers can manage, and it adds full XLR line and microphone inputs plus a guitar input for plugging in real gear - the Stormbox Blast is aux/Bluetooth only. Both run a similar 30ish hours on battery, though the Rockster Air 2 is rated higher at 58.
Buy the Stormbox Blast if you want most of the sound for a third of the price and prefer something you can actually carry. Buy the Rockster Air 2 if you need to fill a bigger space or plug in instruments and mics, not just stream from a phone.
If water resistance matters to you, the Tribit Stormbox Blast at IPX7 (brief submersion) holds up far better than the Teufel Rockster Air 2 at no water resistance.
