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 think this a great idea for a thread, it is amazing to me that more people do not realize the effect a room has on the overall sound of a system.
If you have a well engineered speaker and a treated room, exceptional sound can be achieved.

not sure how to post my in-room response, but it is pretty snazzy, especially since i am incorporating Anthem's new room control.

the above response is taken with a USB microphone that is not accurate above 10k.

another big issue with good system setup is properly integrating a sub. Proper Phase adjustment is cruical.
