Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Ultimate Ears Megablast is the better pick: it ranks #77 of 93 large speakers by sound quality (rated 2.8/5), against #79 (rated 2.7/5) for the LG PN7. Both are rated below 3.0/5 among the 93 large speakers, and the Tribit Stormbox Lava, ranked #3 at $100, is a better place to start if sound quality matters.
Buy the Ultimate Ears Megablast only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Lava instead.
