Short answer: the Marshall Stockwell II. It ranks #11 of 105 large speakers by sound quality (rated 4.5/5) at $226 and is still sold new; the Sony SRS-XG300 ranks #77 (rated 3.1/5) and is discontinued, so it is only an option used. The Sony SRS-XG300’s replacement, the Sony ULT Field 5, is rated 3.5/5 at $348.
The Marshall Stockwell II is the better-sounding, deeper-bass choice. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Its bass reaches about 44Hz before falling 10dB, against 54Hz for the Sony SRS-XG300. At 3.1 lbs (1.4 kg) it weighs much less than the Sony SRS-XG300 at 6.6 lbs (3 kg). The tradeoff: Not very loud, and the added DSP reverb may annoy purists.
The Sony SRS-XG300 is the tougher pick. IP67 dust/waterproof rating. It is rated IPX7 against IPX4 for the Marshall Stockwell II. It links with other speakers (Party Connect up to 100 speakers), which the Marshall Stockwell II cannot. It plays in stereo from a single unit, unlike the Marshall Stockwell II. Watch for: Overly expensive.
Buy the Marshall Stockwell II. It is rated higher for sound quality, and the Sony SRS-XG300 is discontinued, so it is only available used.

The Two Speakers In Full
Marshall Stockwell II: $226.00 Amazon $226.00 eBay
Newer model: the Marshall Stockwell III, ranked lower, rated 3/5, released Jun 2026. It adds power bank charging, app control, adjustable EQ and AAC. Water resistance goes from IPX4 to IP55. See every Marshall Portable Speakers generation.
Pros: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. Its 1.4 kg, claimed 20 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 96dB and mono playback make it a practical option for its intended room or portable use. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Alan Ross prefers it to the Marshall Stockwell III for long listening because it is more neutral and less tiring. Measured bass extension of 44Hz (-10dB).
Cons: Bass is limited by its 44Hz specification. There is no companion app. No EQ adjustment. Not very loud, and the added DSP reverb may annoy purists.
