This looks suspiciously like Fishman's take on Bill Lawrence's Q-Filter. It's a 2-wire passive device called "reactive", which suggests that it's just a coil. And they're close to the same price. Nothing wrong with that, but curious if anyone has tried one.
$30 for the Fluence, and $35 for the Q-Filter.
