More proof of my ignorance coming through...
When a receiver says -10dB. what exactly is that ratio? I understand that a jet plane taking off produces 140+ dB within a reasonable distance. How such a common number equated to the performance of a receiver. Second question would be regarding speaker performance. The stats on the M80s says,"Freq Resp +/-3dB (Hz)34-22K". I understand the frequency reference; however, I don't get why we have a plus/minus of 3 for that value. What is its significance?
If anyone would like to point me to some good reading, rather than explain in their own words, please don’t hesitate.
Thanks!
