speaker efficiencey?? Starting point...? 92db??


I recently purchased an spl meter to map out the response on my HT system. The manual for my Yamaha Rx1500(using as pre/pro) says to start at 0 db volume and test each channel from the listening position to 75db. I went through each channel(7.1 sys) and at 0 db i only had to adjust the left front and right surround speakers slightly to hit the 75. All other channels hit 75db at 0db.

Iam guessing that it would be correct to say that my requency response is relatively flat. Forgive my ignorance but i am just starting out in this crazy world of HT. My speakers have an efficiency rating to 92db. what exactly does the efficiency rating mean?>??

Ah, um, I think i was less confused when i initiated the thread. Maybe my question was incorrectly phrased do to my ignorance. Basically, since being on the gon I have learned that your "system" is only going to sound as good as your equiptment and "set up"(bass mgt, speaker distance, etc, etc.) is. I know my Yamaha, Adcom, Def tech system is, well, some sort of "fi", call it what you will, and i am not even sure i will get any benefit out of mapping out the frequency response from my speakers. I just figured it couldnt hurt. I guess i may be confusing the terms themselves at this point.

As per the manual on my Yamaha i set the main volume to 0db and sent test tones to each speaker. Now, the Yamaha does have this Ypao(mic that you put in your main listening position and it calibrates speaker distance, level, "small/large", eq, etc. I have done the set up numerous times and after each set up i always find that the overall sound can best be described as sort of "meak". I have to turn the volume up much further. When i manually check the speaker settings the fronts and center are set from (1db)left to 0 center and .5db right. Usually i end up setting them to 4 db, 3db and 3.5 respectively to get some more "oomph". This is why i puchased an spl to compare what the YPAO settings were to a handheld spl. NOW, i am clueless!! When i manually adjust the speaker levels am i screwing up the soundstaging, etc.?

Is there a site for maybe "midfigon for newbies".
Audiokinesis, dude what are heck are ANECHOIC CONDITIONS anyways, better yet maybe i dont want to know. I am just looking for inexpensive tweaks here and there to get the maximum out of the equiptment i have well basically because, well how my wife phrased it " this stuff needs to last you for the rest of your natural born days". I think that means she wont even let me by a dictionary to look up anechoic.
