Short answer: the Teufel Rockster Air 2. It ranks #5 of 14 battery-powered PA speakers by sound quality at $499.99; the Soundboks 4 ranks #6 and costs $1199, which makes this an easy call rather than a real tradeoff.
What the Soundboks 4 offers: Tied for the loudest battery powered speaker. Removable 40 hour battery. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Watch for: Very large. Not as neutral or as deep of bass as the above Partyboxes. Not stereo. External power brick for charging.
What the Teufel Rockster Air 2 offers: 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. Watch for: 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.
Buy the Teufel Rockster Air 2. It ranks higher for sound quality than the Soundboks 4 and costs less, which settles it without a real tradeoff to make.
Water resistance is not close: the Soundboks 4 is rated at IP65 (water jets), well ahead of the Teufel Rockster Air 2 at no water resistance.
