[QUOTE="Ivan Beaver, post: 23252, member: 30"] Re: Beta testers You can "kinda" do polars by using the spectrgraph and attaching a string at a center point on the loudspeaker to use as a distance gauge and walk around the cabinet. Now ground reflections and such will enter into the equation, but you can get an idea of what is happening. There will be no angle numbers associated with it, so you have to know where the start-stop and center points are on the graph and how far off axis you were during the measurements. I like to tap on the head of the mic for each of the start-middle-stop locations to give a reference for later on. It shows up as a nice large spike in the level. [/QUOTE]
