Short answer: the Sony ULT Field 5. It ranks #59 of 120 large speakers by sound quality (rated 3.5/5) at $348 and is still sold new; the LG PN7 ranks #95 (rated 2.7/5) and is discontinued, so it is only an option used.
On the Sony ULT Field 5 side: IP67 rated, dustproof and water resistant. The catch: Bass not as deep as others in the category, and sound quality overall is just okay.
Buy the Sony ULT Field 5. It is rated higher for sound quality; the LG PN7 is no longer sold new.
