To hang the speakers on the white ceiling, I turned to these satellites.
Clearly this is pitched and flat.
No low (but not at all!) And treble that could saturate quickly.
So I changed my tune and I installed 4 satellites in addition to my current system and 7.1 reparameterized my amp to use these high additional speakers .... and here I confess that the audio "global" brings a real plus in the spatiality of the sound.
So recommended only in addition to an existing home cinema to provide enhanced sound circle.
