My Room Response Graph

[Echomalinois]

Just thought that I would post this here. I have been playing around with REW for the past few days and was finally able to generate a graph of my in room response. The sub is a VTF2-MK3 in a small 900-950 cubic feet room that is sealed. I still may try some other spots in the room but have to say the response from this location is nice :D.

Can you post a before and after, and show where you put the filters?

Thanks

If you can believe it, this is with out an EQ. It is a bedroom that has a bed and other things in it which may explain the fairly smooth response. I started with this to see if I would need to use an EQ, but if this is correct I will not have to. I still have to play around with REW and make sure that this was not some kind of fluke. But after 3-4 days of playing to finally get a graph that I feel represents the room, I am taking a break from that program. I will more then likely play around some more this weekend, I still want to play with phase and try one other spot in the room. Not that I am not happy with this, I feel like it started to drop off after 20hz faster then it should. To me the lower end feels stronger then this graph represents. Also forgot to say that my sub is in max extension for this chart.

Very impressive. Is this with the Rat Shack meter used as mic?

Yup, used a digital RS meter for the mic. With the REW, they supply an adjustment program that makes up for the RS meters inaccuracies.
