Wid... Response curves are actually no mystery. If you have a receiver/amp that has its increments in dBs (I have a Denon 5800 that does, for example) and something like a Stryke Audio disc, you can actually get an idea for yourself. Play a 1000 Hz signal at, for example, -25 dB on your receiver... then increase it to -22 dB ... the is a 3 dB "peak" ... then play -28 dB ... that is a 3 dB "valley" ... Now when you look at a response curve, you can have an idea what it means when you see these 5-6 or higher peaks and valleys... in the midrange and treble, it is pretty signifigant.
For now... try that experiment... and see what you find out.
John K ... It is also interesting to take an ETF room corrected response and compare that to a raw in-room respone... just so you know how badly your room is messing with you ...
