Pseudo anechoic speaker measurements.

[aceinc]

I would like to approximate an anechoic speaker measurement from 200hz to 20khz in an 11'x15' room. To do this I assume I would need to do gated measurements. Within REW, I believe gating is controlled via the IR panel which I have never used. Could someone explain what a good set of values for this panel would be for the measurement & environment I have defined.

Also if you could provide a brief explanation why the values were chosen, and if I should be setting other parameters.

If this has already been explained elsewhere, please provide a link.

There is thread here which may also help you. IIRC the method has aligned to Klippel NFS measurements quite well.

How to make quasi-anechoic speaker measurements/spinoramas with REW and VituixCAD

Quasi-anechoic measurements are a way to capture the 'real' frequency response of a speaker without the influence of a room. They are called 'quasi-anechoic' because they have the potential to get you really close to the results one might achieve with a non-reflective environment like an...
