How ever simple it might be to put this sort of thing on a thread it is still very impressive. Kudos Njonker, maybe more will follow.
Tuning speaker / room response?
I finally did an experiment this afternoon to check out my speaker and room response. The graph below shows the results:
I got this using the Stereophile Test CD 2 tracks 15 through 18 using my system. The first one provides pink noise, the others give warble tones at the various center frequencies shown in the chart.
A Radio Shack SPL meter, in fast mode, C weighted, was used to to capture SPL levels. The meter was in the 80dB range. As C weighting rolls of above 10kHz, I did not show the rest of the spectrum.
Now this does not look all that flat to me, but I have never done this before. Can anyone give me an opinion on how good or bad this looks?
Also, it looks to me like a little room tuning might help. Anyone have any suggestions as to where to start with this?
