Short answer: the Teufel Rockster for output, the Bose Soundlink Revolve+ II for everything else. The Rockster is the loudest battery powered speaker around with deeper bass than the Soundboks 2 or 3, but it is extremely heavy, hard to carry, not stereo and sold only in Europe. The Revolve+ II stays consistent from any angle and is far easier to live with, despite overly boosted bass.
Bose Soundlink Revolve+ II’s strengths: Its true 360 degree sound stays consistent no matter where you stand around it, unlike most portable speakers. The tradeoff: its bass is overly boosted and warm sounding, the mids are boosted, the treble is rolled off, and it’s only IP55 rated.
In favor of the Teufel Rockster: It’s the loudest battery powered speaker around, with deeper bass than the Soundboks 2 or 3. The downside: it’s extremely heavy and hard to carry, isn’t stereo, and is only sold in Europe.
Buy the Bose Soundlink Revolve+ II for a medium speaker; the Teufel Rockster suits a large party speaker instead.
Battery life favors the Teufel Rockster: rated for 30 hours against 17 hours for the Bose Soundlink Revolve+ II.
If water resistance matters to you, the Bose Soundlink Revolve+ II at IP55 (water jets) holds up far better than the Teufel Rockster at no water resistance.
