Short answer: the Sony ULT Field 5 for better sound quality, the W-King D9 for the lower price. The Sony SRS-XG300 ranks higher than the W-King D9 (#77 vs #91 of 105 large speakers) but is discontinued. Its replacement, the Sony ULT Field 5, is rated 3.5/5 at $348; the W-King D9 is rated 2.5/5 at $71.24, $276.76 cheaper.

The Sony SRS-XG300 is the better-sounding choice. IP67 dust/waterproof rating. It links with other speakers (Party Connect up to 100 speakers), which the W-King D9 cannot. Watch for: Overly expensive.
The W-King D9 is the deeper-bass, longer-running pick. A compact 4.4 lbs (2 kg) boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Its bass reaches about 47Hz before falling 10dB, against 54Hz for the Sony SRS-XG300. It is rated for 40 hours of battery against 25 for the Sony SRS-XG300. At 4.4 lbs (2 kg) it weighs noticeably less than the Sony SRS-XG300 at 6.6 lbs (3 kg). Watch for: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Buy the W-King D9 if price matters most. For better sound quality, the Sony ULT Field 5, the replacement for the discontinued Sony SRS-XG300, is rated higher but costs $348.

W-King D9: $71.24 Amazon $71.24 eBay
Pros: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Long-term owners praise its loud, punchy character and useful indoor/outdoor voicing for casual outdoor listening. Measured bass extension of 47Hz (-10dB).
Cons: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume. There is no app or adjustable EQ, and its bass does not reach as deep as larger rivals, so it is better suited to energetic background music than neutral listening.
