Tribit Stormbox Blast 2: $279.99 Amazon eBay
Older model: the Tribit Stormbox Blast (rated 4.5/5).
Pros: Pretty deep bass. Measured bass extension of 40Hz (-10dB).
Cons: Sounds quite muddy with the boosted lower and upper bass. Boosted treble around 6kHz. Xbass mode makes it sound even more muddy. Nowhere near as neutral and balanced as the first Blast and a big downgrade unless you only care about max volume
