According to Peter Lyngdorf about 85% of the sound we hear comes from the room and 15% from the loudspeakers.
"one of the things that people don't realise is that if they buy the best speakers in the world and put it in a normal living room about 85% of the sound they hear is coming from the room"
"speakers are 15% of the sound and the room is 85% and those 85% typically are not so good"
"when you can digitally compensate in the correct way, we can actually make sure if you buy Bowers & Wilkins speakers or DALI speakers or really good loudspeakers it will sound the best that that speaker can sound in your own room and that is what really matters"
Btw, i am using a TDAI-3400 with RoomPerfect room correction engaged.
