Short answer: the JBL Partybox Stage 320 on ranking and features. It ranks #3 of 43 against the Sony SRS-XP700’s #13 of 43 and costs $499.95 against $314.95, with convenient handle and wheels. The XP700 uses dual 6.69” woofers and multi-tweeter X-Balanced Speaker Units with a rear tweeter for 360 effect, but it has a weird midrange peak, while the Stage 320 is slightly sibilant in the treble at full blast.
Buy the JBL Partybox Stage 320. It is rated higher for sound quality and still sold new, while the Sony SRS-XP700 is discontinued.
There is a real gap in water resistance: the JBL Partybox Stage 320 at IPX4 (splashing) against the Sony SRS-XP700, which has no water resistance.

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.

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.
