Short answer: the Sony ULT Field 7 for better sound quality, the W-King X10-1 for the lower price. The Sony ULT Field 7 ranks #59 of 98 boombox speakers, rated 3.2/5, at $448.99. The W-King X10-1 ranks #84, rated 2.4/5, at $139.99, $309 cheaper.
The Sony ULT Field 7 is the better-sounding, deeper-bass option. Its bass reaches about 52Hz before falling 10dB, against 63Hz for the W-King X10-1. It supports LDAC Bluetooth, which the W-King X10-1 lacks. It links with other speakers (Party Connect up to 100 speakers), which the W-King X10-1 cannot. Watch for: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
The W-King X10-1 is the longer-running, lighter pick. It is rated for 42 hours of battery against 30 for the Sony ULT Field 7. At 6.5 lbs (2.95 kg) it weighs much less than the Sony ULT Field 7 at 13.9 lbs (6.3 kg). The tradeoff: Rolled off treble, not much bass.
Buy the Sony ULT Field 7 if sound quality matters more than the price. Buy the W-King X10-1 if the price matters more than sound quality.
