Short answer: the Marshall Middleton. It ranks #33 of 120 large speakers by sound quality (rated 4.0/5) at $257.52 and is still sold new; the LG Xboom Go PL7 ranks #106 (rated 2.4/5) and is discontinued, so it is only an option used.
The Marshall Middleton is the better-sounding, louder pick. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and a detachable strap. Alan Ross Reviews measured it at 99dB at full volume, against 95dB for the LG Xboom Go PL7. It links with other speakers (Marshall Stack), which the LG Xboom Go PL7 cannot. Watch for: 5db dip at 1.7kHz and 6.3kHz.
Why pick the LG Xboom Go PL7: A fun, waterproof portable with glowing light rings, a long battery, and stereo pairing for casual outdoor listening, now discontinued. The tradeoff: Independent testing finds weak low-bass and top-end extension, a narrow soundstage and uneven off-axis response.
Buy the Marshall Middleton. It is rated higher for sound quality; the LG Xboom Go PL7 is no longer sold new.
