I need help with my room


Rooze came over yesterday with a TACT room analizer(?) which showed the frequency response of my system in my room. I will try to post pictures of the results, but suffice it to say that the entire frrequency response is muted. I have one spike at about 40Hz but everything is an average of 6db below what it should be.

There are pictures of my system so you can see some of the room, although I have taken down all my room treatments. This did help, but not enough. The room is carpeted and has a cheap acoustic tile ceiling. I was wondering if fire rated tiles would help in the midrange and treble?

Any ideas for getting me to where I should be? HELP!

It sounds like you're overreacting. I have been using a TACT system for close to 2 years and it's a wonderful piece, but it can easily be misused or misinterpreted. The key to using the TACT is obtaining an accurate measurement set. For best results you need to set the measure clicks to at least 50 and take readings from several different positions approximating where your head is during normal listening and use the averaging function. It's very important that the room is absolutely quiet during the measurements. HVAC noise, passing vehicles, cycling refrigerators can all screw up the measurements. Assuming all this was done correctly you still have to understand what the measurements are telling you. NO ROOM EVER MEASURES FLAT IN THE BASS. If all you have is a single spike at 40Hz and otherwise the system measures smoothly, then you've already done a great job. A relatively narrow bass peak can be easily dealt with via EQ or tuned bass traps. Depending on your taste in music, a little bump at 40Hz can be quite helpful in that it adds some growl to bass lines. Flat bass response can sound slightly anemic.

Ask yourself a question - does the system sound muted? Use the measures only as a guide and then let your ears tell you what is right.
Onhwy61's response sounds about right. Where you're measuring has a lot to do, as well as with speaker locations. Simply ploping your microphone in the room and measuring doesn't tell you much. Also, like he said, "is it being used right?"
You really should know what's going on with a room, and how to deal with it. This is why companies like PMI, Rivesaudio, and others get paid for consulting and room correction. There's some science and art to all of this...then you're ear's factor in for final say-so.
Doing some research otherwise will help tremendously.

I don't know if this will help at all but there are three graphs of what was measured in the listening room by Rooze.
