These sit in different size classes, so this is not a straight ranking comparison. The W-King X20 ranks #43 of 113 boombox speakers by sound quality at $229.99; the W-King T9 Pro ranks #38 of 53 party speakers by sound quality at $171.49.
The W-King X20 is the longer-running, lighter option. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It is rated for 24 hours of battery against 12 for the W-King T9 Pro. At 15.9 lbs (7.2 kg) it weighs noticeably less than the W-King T9 Pro at 20 lbs (9.05 kg). It is rated IPX6, while the W-King T9 Pro has no water resistance. The catch: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Why pick the W-King T9 Pro: A rolling party speaker with dual woofers, a removable battery for long events, stereo pairing, and music synced lights. Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the W-King X20 ($229.99) for a boombox speaker; the W-King T9 Pro ($171.49) suits a party speaker instead.
