hi,

https://www.devialet.com/fr-fr/phantom-speaker/phantom-i/phantom-i-103db-light-chrome/


Case 1 : (MIC RTA calibrated at 94 SPL, in living room (not ideal) at 0,5 meter)
Normal mode (latency lowered 190ms to 60ms (minimum) in Devialet Android APP), Volume 90%, MOTU 8A toslink output -> Toslink input : Devialet Phantom I - 103 Db, latency 58ms :

Case 2 : Direct optical mode - latency 58 ms to 2 ms ! - same results, same quality :

Not bad at all, and result will be much better in an Anechoic chamber....

It was my living room, with a lot of imperfection..... but results good....

Sure, if you show almost 400dB of scale in the frequency response, everything is bound to look good. Same for the group delay, your range is 2 seconds. That is massive for audio.

hi,

still good with zoom, delay resonance from my room (big BASS near wall) , should be better in anechoic chamber ...

At .5 meter, anything below 700Hz is mostly room dominated, so would not worried too much about that.

Hi can you measure step response?

Previous versions of Phantom did not have drivers time aligned by the DSP - @mitchco showed in his measurement of the older version Phantom Gold.

I was hoping the new Phantom hardware + recent new firmware , that Devialet fixed this.
