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 JBL Xtreme ranks #72 (rated 3.2/5) and is discontinued, so it is only an option used. The JBL Xtreme’s replacement, the JBL Xtreme 5, is rated 4.6/5 at $349.99.
The Marshall Stockwell II is the better-sounding, longer-running pick. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. It is rated for 20 hours of battery against 15 for the JBL Xtreme. At 3.1 lbs (1.4 kg) it weighs much less than the JBL Xtreme at 5.3 lbs (2.4 kg). The tradeoff: Not very loud, and the added DSP reverb may annoy purists.
The JBL Xtreme is the tougher pick. 15 hour battery. It is rated IPX7 against IPX4 for the Marshall Stockwell II. It links with other speakers (Connect), which the Marshall Stockwell II cannot. It plays in stereo from a single unit, unlike the Marshall Stockwell II. The catch: Issues with bass distortion at high volumes.
Buy the Marshall Stockwell II. It is rated higher for sound quality and still sold new, while the JBL Xtreme is discontinued.

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.
