GUIDE FOR SETTING UP YOUR ROOM

[TheTrueZoltan!]

it’s crazy how much difference it can make. Frequencies get really directional as they get higher up, so it’s really important to set the acoustic centre of the monitors where the manufacturer recommends. [...]

An excellent tip! I hadn't even thought to look in the manual of my Neumanns yet. Instead, I relied on articles on the internet, most of which stated to place the tweeter at or even slightly below ear level. Now I've looked it up and lo and behold - Neumann state that the acoustic axis of the KH 120 A speakers is midway between the tweeter and woofer. So I have now selected the height setting on my stands that most closely corresponds to this specification. The difference is really remarkable. Everything suddenly sounds somehow more direct and the bass also comes across better. I haven't taken a REW measurement yet, but I suspect there will be a clear difference.
