McIntosh XR-7 setup with MQ-104?

Just got a pair of the xr-7's and love them! Ordered a mq-104 to setup my speakers with my room and need to know how to without spending thousands on an octave analyzer. Any suggestions????
On the cheep, go get a $50 Radioshack analyzer and a Test tone cd. Start with the 1K tone and set the volume for 85 db. Then do a reading at each octive at the same volume then put numbers on a graph and then adjust the 104 as needed
