Title: Impedance Post by msa on 03/05/07 at 22:17:27 The "nominal" impedance is given as 8 ohm. What is the minimal impedance and at what hz? Thanks |
Title: Re: Impedance Post by 9anda1f on 03/06/07 at 00:22:20 Hi msa, Just as every speaker has a different frequency response, so do they have a different impedence across the frequency spectrum. Look at the Fostex FE-166 graph: http://www.fostexinternational.com/docs/speaker_comp/pdf/fe166erev.pdf The top curve is frequency response, the lower curve is the impedence at each frequency. Note the peak in impedence at 50 Hz ... right at Fs. Also note that the nominal impedence is also the lowest across the chart and falls in the span between 300-600 Hz. From the Fostex overview page: Quote:
Hope this helps. 9anda1f |
Title: Re: Impedance Post by msa on 03/06/07 at 01:11:21 Yes, it did help. Thanks. It directed me to the Fostex website where I could look up the 208, which is in the HDT. Its graph shows the lowest impedance is 8 ohms. |
Title: Re: Impedance Post by john67 on 03/06/07 at 17:10:44 msa, I think what you want is the FE206E. John |
Title: Re: Impedance Post by msa on 03/06/07 at 18:06:41 Oops! You are correct. The answer is the same: lowest impedance is 8 ohms. Thanks |
