JBL Partybox Stage 320: $499.95 Amazon B&H Photo Video eBay
Newer model: the JBL Partybox 330, ranked higher, rated 4.6/5.
Pros: Among the best-sounding party speakers in its size class, and it keeps more bass than the JBL Partybox 310 at high volume. Two 6.5-inch woofers and two tweeters run on 240W, with a removable battery rated for 18 hours, a 5-band app EQ, mic and guitar inputs and Auracast linking. A handle and wheels make the 16.5 kg cabinet easy to move, and the color lighting modes are customizable.
Cons: Slightly sibilant in the treble at full blast. Very large.

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.
