Short answer: the Sony ULT Field 3. It ranks #57 of 134 medium speakers at $148; the Yamaha True X Speaker 1A ranks #93 and costs $150, so there is not much of a tradeoff to weigh.
What the Sony ULT Field 3 gets right: IP67 rated, dustproof and water resistant. The tradeoff: Sounds a bit hollow, a bit boosted in the treble.
On the Yamaha True X Speaker 1A side: Doubles as a wireless surround speaker for Yamaha True X soundbars, or a standalone speaker via ‘Solo’ mode. The tradeoff: Not very deep bass, upper mids peak that makes voices sibilant.
Buy the Sony ULT Field 3 if the ranking matters more than the price. Buy the Yamaha True X Speaker 1A if the price matters more than the ranking.
