Short answer: the Sony ULT Tower 5. It ranks #5 of 51 party speakers by sound quality, rated 4.5/5, at $348. The W-King T9 Pro ranks #36, rated 3.0/5, at $171.49, $176.51 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Sony ULT Tower 5 is the better-sounding, longer-running option. A powerful party tower with deep bass, a removable long battery, and mic and XLR inputs for karaoke or DJ use. It is rated for 20 hours of battery against 12 for the W-King T9 Pro. It is rated IPX4, while the W-King T9 Pro has no water resistance. It supports LDAC Bluetooth, which the W-King T9 Pro lacks. The catch: It has a shorter 20-hour battery claim than the Sony ULT Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
The W-King T9 Pro is the lighter choice. A rolling party speaker with dual woofers, a removable battery for long events, stereo pairing, and music synced lights. At 20 lbs (9.05 kg) it weighs noticeably less than the Sony ULT Tower 5 at 28 lbs (12.7 kg). Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the Sony ULT Tower 5. It is rated higher for sound quality, and saving $176.51 with the W-King T9 Pro does not make up for the sound-quality gap.
