Short answer: the JBL Xtreme 3 is the portable pick, the Teufel Rockster 2 the outdoor powerhouse. The Xtreme 3 has better treble and deeper bass than the Xtreme 2 and more balanced sound than the Xtreme 4. The Rockster 2 is more evenly tuned than the JBL Partybox 720 and uses a horn-loaded tweeter for consistent off-axis sound and clean long-distance projection, at the cost of some bass depth and high-volume output.
Buy the JBL Xtreme 3 at $269.95 for a large speaker, or the Teufel Rockster 2 at $1,269.94 for a large party speaker instead.
If water resistance matters to you, the JBL Xtreme 3 at IPX7 (brief submersion) holds up far better than the Teufel Rockster 2 at IPX2 (light drips).
