[QUOTE="Brandon G Romanowski, post: 42366, member: 57"] Re: Dual 18" Separate Chambers ?? How would I measure impedance at different voltages? with a VOM and a sine wave generator .. and patience? There's no way to do it with a WT3 is there ? I did do an RTA where I turned up pink noise in 3dB intervals with infinite averaging for 30 seconds at a time. the first few captures looked the same, after a certain level (I didn't keep track of voltage) the out of band noise and distortion would increase by 6dB or more in some spots, after that it got to the point where the pass band information would not increase by the 3dB but again the slop would.
