Room correction with Phantom

[Snoopy8]

I´ve done a  quick  room analysis which resulted to a much lower bass level,
Running on wifi it was  like  a subwoofer was cut down.
Running on Bluetooh  the Ghost are keeping their imponator bass strength.
I have to mention that you can adjust the treble range  via the DSpeaker but
you cannot attenuate the bass range just  raising up...

Welcome to the forum...

If I understand correctly, your chain looks like thus:
TV to Box Connect - optical - DSpeaker - optical - Dialog

I am confused by what you mean when you refer to wifi and bluetooth.  Are there other devices in the music chain?   How do you connect by wifi?  If you are using Bluetooth to the Dialog, you are bypassing the DSpeaker.

Please read the DSpeaker manual carefully.  Done correctly, DSpeaker will improve bass.
