Short answer: the Zealot PT21. It ranks #12 of 51 party speakers by sound quality, rated 4.1/5, at $225.86. The Rockville Rock Party 6 ranks #51, rated 2.0/5, at $73.43, $152.43 cheaper, which does not close the gap in sound quality.
The Rockville Rock Party 6 is the lighter option. 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 Zealot PT21 at 20.7 lbs (9.4 kg).
The Zealot PT21 is the better-sounding, longer-running option. A lighter party speaker with surprisingly deep bass for the money, a long battery, and a wireless mic for karaoke. It is rated for 60 hours of battery against 6 for the Rockville Rock Party 6. It is rated IPX5, while the Rockville Rock Party 6 has no water resistance. It links with other speakers (PartyAdd up to 100 speakers), which the Rockville Rock Party 6 cannot. The catch: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
Buy the Zealot PT21. It is rated higher for sound quality, and saving $152.43 with the Rockville Rock Party 6 does not make up for the sound-quality gap.
