Short answer: the Sony SRS-XP700 for hardware, the Samsung MX-ST50B for even tone. Samsung sounds reasonably balanced at $300 but its bass is not as deep as a Partybox 110 or other higher ranked speakers. The Sony’s dual 6.69-inch woofers and multi-tweeter X-Balanced units with a rear tweeter aim for 360-degree sound at $314.95, with a weird midrange peak as the catch.
Buy the Sony SRS-XP700 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 Club 120 instead.
There is a real gap in water resistance: the Samsung MX-ST50B at IPX5 (water jets) against the Sony SRS-XP700, which has no water resistance.

Samsung MX-ST50B: $300 Discontinued Amazon eBay
Pros: A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. Hands-on reviews find it capable of clear, punchy sound and impressive output for indoor parties, while its 18-hour claimed battery supports more casual use away from mains power.
Cons: Output drops sharply to 90W on battery, so it needs mains power for its full impact. Bass is not as deep as stronger dedicated party speakers, and at 11.9kg its tall enclosure is less convenient to carry. It lacks TWS stereo pairing, so the Group Play feature favors shared party coverage rather than a conventional stereo image. Discontinued.
