Short answer: the JBL Partybox 310 for reference-level bass, the Onn Large Party gen 2 if the price gap matters more. The discontinued Partybox 310 reaches an exceptional 32Hz at -10dB, the deepest bass of any battery speaker here, with the most balanced sound in its class and app EQ, though it weighs 37.5 lbs (17 kg). The Onn is far cheaper and lighter with karaoke mic and guitar inputs and wheels, though Consumer Reports found its bass boomy and treble smeared with no app or EQ. The JBL Partybox 310 is discontinued; its replacement is the JBL Partybox 330. If you are buying new, get the JBL Partybox 330.
