    I hear you guys talk about db levels all the time. I used the Video Essentials disk to calibrate my dual 20-39CS+/s1000 subs. I put the subs at +10db over the mains. I turned it up an boy they rock but ........... According to my Radio Shack metter I am not getting the high dbs you guys get. I turned this thing way way up. It was really loud and the Phantom Mencace made me feel like bugs were crawling on my hair. I have a room that is 20x18 with 12 foot ceilings. One side opens up to the hall way and dinning room and the other side has an eight foot opening to the kitchen at the back. I currently have the subs in the corners in the front. They registered 73.5db in the corners and 74db when put together in one corner. Someone told me that i might lose some lows or some of the flatness having them in different corners or that they might be canceling each other out. I currently have an Onkyo 595 reciever. Darn how loud is 110db. I can not imagine! What do you guys think? Thanks for your time!!!

    sit in the sweet spot hold the meter in your lap set volume at reference watch for high peaks on the meter.I get about 120 db on phantom menace with 2 46plus.hope this helps. oh both in the same corner gives you a lot more head room.

    Brian,

    Video Essentials is recorded such that you are NOT hearing reference levels when you run that calibration routine.

    Playing a movie is TOTALLY different. With +10dB on your subs by the meter you are probably 12dBs over actually. This is roughly 4 times what you "should" be. Even I run my subs up high but watch your master levels when viewing movies. That is just a TON of bass and if you run your movies anywhere close to the level your receiver display was at when you calibrated your system, you could blow out a driver.

    Thank for the reply guys. Ron I did not try to get over 100db with video essentials hehe. I meant while watching a movie it did not get up to that level. When the guys in here state that their subs got over 100db what are they watching?

    I just thought of something. i am doing this all wrong. It can not be right to test for maximum spl with a movie either. Some movies have more low bass than high bass. There must be some type of test tones disk or something. I know my subs must be fine. Heck the feeling of bugs on your head is a lot of bass!!!!

    I found out that I was putting my spl meter on slow instead of fast which just gives me an average. All is well now. I will go home today and retest for peaks in the movie with the spl meter on fast. I will also download some test tones and use them.
