    I just read the NEWBIE FAQ on speaker calibration, but i wanted to double check in "laymans terms".

    I put the sound reader at my ear level and start with the left speaker....i turn it up until my sound reader stays on 75 DB....on my receiver thats number "58".
    I leave the receiver at "58" and i adjust the center and the backs so its reading 75 DB...all while my receiver is still at "58".

    Thats it, done?

    Also then when i watch movies, its best to watch them on volume "58"......?

    Thanks a ton guys.

    The procedure is correct.

    Well you should use test-tones from your receiver or the Video Essentials or Avia DVD for the sound.

    A inexpensive camera tripod is a handy tool to mount the SPL meter at ear height. Make sure to angle the meter up about 45 degrees - you dont point the meter at each speaker

    Many people find that with their speakers calibrated to 75 db, they adjust their subwoofers to produce 80 db for a bit of extra umph.

    But No, you dont listen at this level. You adjust each individual movie to taste or out of consideration for others in the house.

    The 75 db is the THX reference level and it's loud enough that you should be able to hear everything clearly. So you use this level for calibration. But not for day-to-day listening.

    And some movies - the center is a bit too quiet so dont be afraid to bump the center 1 or 2 settings if needed. Just remember to put things back to the calibrated level at the end.

    Thanks guys.
    I'm just trying to get prepared for my new house and all new system this coming weekend...my god i can't wait.

    I bought a digital reader from Radio shack today....i calibrated my system in here for fun ( even though i move in a few days and all new stuff coming in).

    F left = 64
    Center = 79
    F right = 67

    B left = 85
    B right = 76


    Pretty crazy stuff and i wish i found the this board years earlier!
    Thanks for the tip on my subwoofer...setting it to 80...i had NO idea where to begin with it.
    Now if i can figure out where in my room to set it up...

    Instead of starting another thread on this same subject I have a question. I'm not trying to hijack the thread though. When calibrating do you reset all you speakers to 0 and then do reference tones. Set center to 0 turn up volume to desired calibraring level. Then match all speakers to that. Is this correct?

    I'm a little confused.

    If I calibrate all my speakers at 75 except for the woofer at 80, does that mean that all the speakers will be playing the same loudness during a movie? I always thought that my rear/sorrounds were supposed to sound at a lower volume than the fronts. Should all 5 speakers be just as loud? I'm not talking test tones here, I'm talking real movie experience.

    Thanks,

    Mirko

    Dustin are you mounting you rears to the wall or using stands. I just took mine off stands and wall mounted them. It sounds so much better. I just thought I ould add that before you set yours up in your new house.

    Mirko, if you set all 5 speakers to the same level, then you will hear movies as they were intended to be heard. You are correct that the surround speakers are usually quieter that the mains, but that is because of the way the movie was mixed, not the way the speakers were calibrated.

    I bought speaker stands for the back...i didn't know they sound better being mounted on the walls.....interesting.

    They sound a lot better? how and why? AHHHH so much to learn.

    One last question....ok, mabye not the last [​IMG]

    How far away am i suppose to put the back speakers?
    I know there suppose to be 2-3 feet above ear level....but how many feet away from my ears?

    currently my left speaker is only about a foot away and my right is about 5 feet away......so thats for a 3 person couch and i sit on the left [​IMG]

    Thanks guys

    I'm also going to assume for the front speakers....they can just be beside the TV? Its a 65" so its pretty long.

    When it comes to speaker placement, you will hear various opinions. I prefer the rear speakers to be located behind the listening position rather than the sides. Also, I like a lot of breathing space for all of the speakers. You can imagine that it would not be desireable to have your main (front) speakers located 1 ft away from the listening position. I use the same logic for the rear speakers as well. If your room can accomodate it, try placing them a few feet behind the l.p. and at ear level or slightly above.

    I get distracted when the onscreen action dictates sound coming from the rear but the sound comes from the sides.
