Short answer: the Sony ULT Tower 5. It ranks #5 of 51 party speakers by sound quality, rated 4.5/5, at $348. The Rockville Rock Party 6 ranks #51, rated 2.0/5, at $73.43, $274.57 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Sony ULT Tower 5 is the better-sounding, longer-running pick. A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. It is rated for 20 hours of battery against 6 for the Rockville Rock Party 6. It is rated IPX4, while the Rockville Rock Party 6 has no water resistance. It supports LDAC Bluetooth, which the Rockville Rock Party 6 lacks. The tradeoff: It has a shorter 20-hour battery claim than the Sony ULT Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
The Rockville Rock Party 6 is the lighter choice. A budget battery party speaker with a woofer, tweeters, Bluetooth, and an aux input. At 11.9 lbs (5.4 kg) it weighs much less than the Sony ULT Tower 5 at 28 lbs (12.7 kg).
Buy the Sony ULT Tower 5. It is rated higher for sound quality, and the $274.57 saving on the Rockville Rock Party 6 is not enough to make up the difference.
