Short answer: the Stage One if budget genuinely isn’t a factor and you want the most rugged, longest-running speaker of the two; the Rockster Air 2 for nearly everyone else. These rank #5 and #2 out of 14 party-size speakers, at $499.99 and $1,450, with the Stage One costing $950.01 more - nearly three times as much.
The Stage One is the more extreme speaker in almost every spec. Its dual swappable batteries give it a 100-hour rating - the longest of any speaker we’ve covered - against the Rockster Air 2’s already-long 58 hours, and it holds up at full blast for 12-plus hours on top of that. It also carries an IPX6 rating against the Rockster Air 2’s none, adds XLR output alongside XLR input for chaining into other pro gear, and uses the same high-efficiency driver approach that reaches 2-3x the volume of a typical speaker at the same wattage.
The Rockster Air 2’s advantage is almost entirely price and weight. It’s under a third of the Stage One’s cost and nearly 4 kg (8.8 lbs) lighter at 14.15 kg (31.2 lbs) against 18.1 kg (39.9 lbs). Both take real microphone and line-level input over XLR, and neither is tuned for deep bass over raw loudness.
Buy the Stage One if you need the most rugged, longest-running speaker here and the price is a rounding error. Buy the Rockster Air 2 if you want most of the same idea - real inputs, serious battery life - without the Stage One’s price or weight.
Water resistance is not close: the Electrotec Stage One is rated at IPX6 (powerful water jets), well ahead of 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.

Electrotec Stage One: $1450 Electrotec Audio eBay
Pros: An exceptionally capable battery-powered PA: dual removable batteries deliver a claimed 100-hour runtime, and high-efficiency drivers deliver very high output with a measured 48Hz -10dB bass point. It adds app EQ, IPX6 protection, mic and XLR inputs/outputs, USB playback and low-latency SKAA linking, making it unusually flexible for events and performers. Measured bass extension of 48Hz (-10dB).
Cons: It prioritizes maximum output and endurance over truly deep bass, so it will not replace a dedicated subwoofer for low-frequency-heavy music. At 18.1kg it is a substantial carry, and its focused PA-style presentation is less suitable for wide, relaxed living-room listening.
