[QUOTE="Max Warasila, post: 209443, member: 3845"] Hi, all. I finally made a little impedance measurement setup in LIMP today, and I'm getting some surprising results. First, when I measured one of the B&C 12NDL76 drivers I had from the DIY Mid Hi project, it showed an Fs of 58Hz, which is markedly higher than spec. I went on to double check the Re value, and that's significantly off, too - 4.8 Ohms instead of the specified 5.3 Ohms. Are these measurements typical deviations from spec, or should I look at my setup for potential issues? Thanks. [/QUOTE]
