Devialet weird sound

[ragwo]

Should i be worried?
I have no idea this is bad for the speaker or not.

You can't damage the speaker, the DSP trickery prevents it.

so the full story is that i had my first phantom gold, that one did the same pof sound, after a few months there was a problem that sometimes the bass was completely gone. After i unplug the phantom an plug it back in it worked again. i had contact with devialet, they gave me a new one, i got the new one and it had the same pof sound after a few months the phantom shuts down if i play a movie with a lot of bass, i had contact with devialet again and they gave me a new one. that one did not make that sound, but i had it only for 3 weeks(i tested the movies with bass and it perform perfect) then i switched to the new matte ones in a stereo pair and now i have 1 with the pof sound but the performence is great. so i have no idea if it was just coincidence that the ones with a pof faild on me. i think i just had bad luck and it has nothing to do with the pof sound, bcs it would surpise me that it wil damage the speaker like u said the dsp prevents all damage.

Sorry, after reading the whole story I have no idea of what's going on. Does the pof sound occur in other situations? Have you tried to connect your TV to the other Phantom? Is the optical cable connected to the speaker with the noise?
