Tribit Stormbox Blast 2: $300 Amazon

Tribit Stormbox Blast 2 ranking card

Pros: Pretty deep bass.

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

Setup: Try the EQ from Alan Ross at this timestamp of his video
