These are not really the same size class, and that is the honest framing here. The JBL Xtreme 5 ranks #2 of 120 large speakers by sound quality at $399.95; the Marshall Emberton II ranks #127 of 179 medium speakers by sound quality at $151.99.
The JBL Xtreme 5 is the louder, deeper-bass choice. A large waterproof speaker with deep bass, wide, clean sound at volume and a removable 28 hour battery. Its bass reaches about 43Hz before falling 10dB, against 62Hz for the Marshall Emberton II. Alan Ross Reviews measured it at 110dB at full volume, against 88dB for the Marshall Emberton II. It supports AAC Bluetooth, which the Marshall Emberton II lacks. The tradeoff: High priced.
The Marshall Emberton II is the lighter option. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. At 1.5 lbs (700 g) it weighs much less than the JBL Xtreme 5 at 6.4 lbs (2.9 kg). The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the JBL Xtreme 5 ($399.95) for a large speaker; the Marshall Emberton II ($151.99) suits a medium speaker instead.
