Short answer: the JBL Partybox Encore 2 for off axis sound, the Marshall Middleton II for deep bass. The Encore 2 appears better off axis with its dome tweeters over cone, though it is missing a little bit of upper bass. The Middleton II reaches very deep bass for its size and weight, but that boosted bass drowns out the midrange.
What the JBL Partybox Encore 2 gets right: Appears to have better off axis performance due to the move to dome tweeters over cone. The tradeoff: Missing a little bit of upper bass.
On the Marshall Middleton II side: Very deep bass for the size/weight. The tradeoff: Bass boosted which drowns out the midrange.
Buy the JBL Partybox Encore 2 ($330) for a boombox speaker; the Marshall Middleton II ($330) suits a large speaker instead.
There is a real battery-life gap here: the Marshall Middleton II is rated for 30 hours, the JBL Partybox Encore 2 only 15 hours.
If water resistance matters to you, the Marshall Middleton II at IP67 (brief submersion) holds up far better than the JBL Partybox Encore 2 at IPX4 (splashing).

JBL Partybox Encore 2: $330 Samsclub eBay
Pros: The Encore 2 improves the original with dome tweeters, a less boomy balance, slightly deeper bass, longer battery life and two included wireless microphones. Its compact karaoke-ready design and 7-band EQ make it more adaptable indoors than the earlier Encore.
Cons: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes. The main value is compact karaoke convenience rather than full-range party output.

Pros: Very deep bass for the size/weight. Measured bass extension of 38Hz (-10dB).
Cons: Bass boosted which drowns out the midrange. Dip around 200Hz, peak at 1kHz, dipped at 1.6kHz. Strange frequency response through the mids.
