Short answer: the JBL Partybox 310 for bass and balance. It has the absolute deepest bass of any battery powered speaker and the most balanced sound in the class, with a convenient handle and wheels, though it is very large. The Partybox 300 counters with crisp, crystal clear highs and midranges and hard punchy bass without muddiness, but it is hard to carry, too tall and drags on the ground.
Buy the JBL Partybox 310 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JBL Partybox Stage 320 instead.
If water resistance matters to you, the JBL Partybox 310 at IPX4 (splashing) holds up far better than the JBL Partybox 300 at no water resistance.

JBL Partybox 300: $300 Discontinued eBay
Newer model: the JBL Partybox 330, ranked higher, rated 4.6/5.
Pros: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. 2x 6.5” woofers + 3x 2.25” tweeters, bass boost function, 45Hz-20kHz frequency range. 18-hour battery with 10400mAh capacity. Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units. Measured bass extension of 40Hz (-10dB).
Cons: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead. Discontinued.
