Short answer: the Tribit Stormbox Lava for bass extension, the Harman Kardon Luna 2 for a one-piece portable. The Lava goes deeper than the Boom 2 and firmware 2.0.0 made it much more neutral, but it is quite heavy for its size and still has treble and upper-mid peaks. The Luna 2 stays cleaner at volume and costs $199.95 versus $119.99.
On the Tribit Stormbox Lava side: Fantastic bass extension. Goes deeper than the Boom 2 as seen in the linked video of sound samples. Firmware 2.0.0 is a big improvement in neutrality. Watch for: Quite heavy for the size. Some bass boost way down low. Treble and upper mids have some peaks.
Buy the Harman Kardon Luna 2 at $199.95 if you want a medium speaker. Buy the Tribit Stormbox Lava at $119.99 if you want a large speaker instead.
Battery life favors the Tribit Stormbox Lava: rated for 24 hours against 12 hours for the Harman Kardon Luna 2.
