Short answer: the Motion Boom, and the ranking gap is large. It ranks #14 of 120 large speakers at $109.99; the Soundbox XL ranks #80 at $79.99, $30 less. The Soundcore Motion Boom is discontinued; its replacement is the Soundcore Boom 2. If you are buying new, get the Soundcore Boom 2.
The Soundbox XL’s spec sheet covers the basics: 32W output, IPX4 splashproof, a microSD slot, and a dual woofer setup with a built-in subwoofer. Our notes describe the resulting sound as a little hollow, its one real complaint.
The Motion Boom is the budget benchmark of this class. Our notes call it excellent budget-friendly value with a genuine 24-hour battery and a buoyant waterproof design, and its only knock is being less neutral and detailed than the top of the class.
Buy the Motion Boom for the far stronger ranking. Buy the Soundbox XL only if the extra $30 is a real constraint.
There is a real gap in water resistance: the Soundcore Motion Boom at IPX7 (brief submersion) against the DOSS Soundbox XL, which has IPX4 (splashing).
