Hi,

I've posted this in the ERR forum but it could equally have been posted under any of the other speaker sections.

All the speaker details quote a frequency response figure, in the case of the ERR's this is      32Hz ~ 22kHz.

Surely this is meaningless without the +/- dB range ie if it was +/- 1dB it would be pretty amazing if it was +/- 12db it would be pretty rubbish.

Can someone enlighten me as to the dB range and does it apply to ALL speakers?

Also does the nominal impedance quoted conform to      
the IEC standard for rating loudspeakers (ie does not fall below 80% of nominal)

Many thanks

Thanks Steve I agree that all speakers should publish response at +/-3db.

Sadly there are many (far too many) who use +/-6db, presumably they do this because there +/-3 figures would not look anywhere near as impressive.

With regard to the nominal impedance I an not qualified to debate this, but my understanding is that the 80% is just a way of saying what the minimum is ie so perhaps the simpler question is; what is the minimum for the ERR's

Many thanks

ps Any idea on the current lead time for ERR's, mine is the most recent order shown  :)
