Re: Garage Loudspeaker LabWell the system I made has a lot of integration time which is good against random noise, but as you push the box around the room, and it is sitting inside of or out of a room mode, it could throw off the measurement of Fs by a freq Hz, when everything is lined up perfect. It also throws off the estimate of how damped the box tuning is significantly, which is really irritating when setting the porting.\Plus, like Ivan said, correlated noise will just cause all sorts of crap which you don't want. Lucky the whole room has open insulation covered with cotton on two sides. Works pretty well to keep the garage noise down.
