Frequencys charted..next step??

Ok, so i just charted out my ht room using the Rives cd and radioshck spl. Looks like my main problem areas are a 200hz and 630hz spike. I went ahead and did a map of the room(as per Rives).

So are these major issues that i should try and correct with room treatments or something that is relatively common and i can leave as is. My room is 25x15, carpeted, drop ceiling(8.75ft). The sound sometimes feels slightly "muddied" in the mid area, not sure if this is related to the problem areas i mentioned.

I am more of a diy kind of person, especially when i look at the cost of room treatments costing more than some of my components. Where do i go from here as far as finding the actual problem areas?

newbee,

thats what i am not sure of. How to locate where the spike is. I charted the frequencys on the graph to find the spikes and i did a map of the room, however i am not sure how to actually find where the spikes are......

Shadorne,

I am using def tech 7004 towers which are bipoles. I have played with speaker position as far as the mains are concerned and have found no change. Any ideas?

Newbee,
Placed spl on tripod in "MY SEAT"(sweetspot). Actually, you must have been reading my mind. Initially, i had the tones playing from the mains, then measured again playing tones through 7 ch. stereo.. The 200hz spike is about 10db higher, the other approx 8db higher. I am not sure how i can add the other ch. one at a time but will give it a shot tonight.
My system is a Yamaha rx1500(using as a pre/pro) with an Adcom 7ch amp, 7.2 ch system. I know its not considered "audiophile" equiptment but I'll tell you what, each time i have experimented with a "cheap tweak" that i have learned about through this site and others, there has been a "nice" improvement every time. Soundstage, etc. are like night and day from my initial set up. I have had this set up about a year now and i think once i am finished with room treatments i am going to be done.,.I'll let you know what happens.....thanks for the advice..dz
