A &B testing of the rock in 50 seconds intervals LCR surround and LFE.1


I’ve conducted several tests of the incoming rock sequence

Centre channel front with sub bass extension.


1 playing the centre channel on its own with sub bass extension. The sound has an organic tonal quality, it’s as if the rock is (breathing) as it hits the upper atmosphere shards of rock pieces burst into flames of what I can only describe as shotgun and cannon explosions that reached 103dbc.



Loudness in the dba weighting on centre channel was considerable louder at 82dba was cinematic enough for a small room.

Left and right channel fronts with sub bass extension.




2 playing the left and right on there own with sub bass extension. Music is played a at low level with an odd directional eeriness, as the rock tumbles around and around, as it progressively starts to break apart it’s less louder than that of centre channel, coming in at 102dbc at first with mild 103dbc that was barley within a 1 second apart.

Loudness in dba weighting on left and right upon exploding was at 80.5dba
