These sit in different size classes, so this is not a straight ranking comparison. The Zealot S167 ranks #65 of 108 large speakers by sound quality at $169; the Zealot S78 ranks #103 of 105 boombox speakers by sound quality at $91.38.
The case for the Zealot S167: Zealot rates the S167 at 100W through four drivers: two 92mm woofers and two 42mm units, with a claimed 20Hz-20kHz response and better than 90dB signal-to-noise. Watch for: The official parameter table publishes no IP rating and no verified playback time, and conflicting retail figures (IPX6, 24 hours, even 4 hours) are unconfirmed.
The Zealot S78 is the tougher choice. A robust 9.7 lbs (4.4 kg) party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. It is rated IP67 against IPX4 for the Zealot S167. The catch: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting.
Buy the Zealot S167 ($169) for a large speaker; the Zealot S78 ($91.38) suits a boombox speaker instead.
