Short answer: the W-King X20. It ranks #41 of 98 boombox speakers by sound quality (rated 3.5/5) at $229.99 and is still sold new; the Sony SRS-XG500 ranks #65 (rated 3.0/5) and is discontinued, so it is only an option used. The Sony SRS-XG500’s replacement, the Sony ULT Field 7, is rated 3.2/5 at $448.99.
The W-King X20 is the better-sounding, deeper-bass pick. Its bass reaches about 42Hz before falling 10dB, against 49Hz for the Sony SRS-XG500. The catch: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
The Sony SRS-XG500 is the lighter option. 30 hour battery life; 10-min quick-charge gives 3 hours. At 12.3 lbs (5.6 kg) it weighs noticeably less than the W-King X20 at 15.9 lbs (7.2 kg). It supports LDAC Bluetooth, which the W-King X20 lacks. It links with other speakers (Party Connect up to 100 speakers), which the W-King X20 cannot. The tradeoff: Thuddy upper bass, not as deep bass as others.
Buy the W-King X20. It is rated higher for sound quality and still sold new, while the Sony SRS-XG500 is discontinued.
