Woofers don't move at all when music is playing

[Saintly]

I don't have a Phantom, but I would hazard a guess that it is a very strange coincidence if two in a row did not work. I assume you are getting no bass output? And not playing back flute solos?

The thing is, I am getting bass output.  I don't have a frame of reference for how heavy it should be hitting but it's not too far off from neutral-ish if I had to guess.  

I'm not well-versed in speakers but the bass on this Phantom sounds pretty similarly to my Stax 009 headphones although those aren't known to be bass monsters by any means.

And no, no flute solos haha.
