In room response

Hello, Lately I have noticed more talk of in room freq response measurements. It has been mentioned in regards to room treatment, subwoofers and their intergration, speaker placement, room size, crossover points, listening volume levels, speaker choices in regards to the type of music you listen to and a myriad of other reasons. I for one fell it is quite important and others seem to disagree to its importance in playback of recorded music.

This thread would be a great place for members to discuss its importance, ramifications, reason for being and to discuss results.

I have seen a few members who allready have posted results of the measurements under their "systems page". I just recently posted my freq response and waterfall graph on my "system" link.

I am quite sure that there are members who have allready done in room measurements of freq response, waterfall and RT60 or other measurements. If you are new to this, a program can be downloaded for FREE at the Home Theatre Shack, it is called the Room EQ Wizard. See link below. It would be used for mesurment only for our purposes, although it can be used with equalizers such as Behringer if you so desire.

The only thing you need to provide is a sound level meter, which everyone should own, even if you don't use this program. A very inexpensive one is available from Radio Shack and is a welcome addition to any audiophiles toolbox.

I will start off with my freq response from 15-200 hz at 74db reference level posted here;

I am going to try to run some measurements tomorrow if I have all cables I believe are out in my barn.....should be fun and likely very beneficial.

I would like to do this but dont really understand it all, I have a Behringer unit, Mic and test discs but I dont know if I have the right unit to do this and help on HT Shak was sorta vague and inconclusive...thos there is alot of nice folks over there trying to help.

Wow Bob thanks for the explanation! Do I need any special sound card or are most internal laptop cards good enough (newer computer with Windows Vista).
