So maybe my listening position is just too close from the front speakers, but I don't think so.
No, your distance it perfectly fine.
I fact, I am very happy to know that the SSP-800 is so good that it cannot be self-calibrated.
I'm not sure if I confused matters here.
But then, what is the standard procedure? From what I know, I have measured distances, and tried to set up the gains so each channel provides a SPL of 75dB (and I failed!). I have run REqW too, but I have no idea how I can tweak the settings independently for each channel...
(I have called hifi stores in my city, but no one wants to work on my ssp-800)
note: I bought my unit in Germany
note2: the SPL meter is a cheap one (see here
I'm not familiar with that SPL meter, so cannot vouch for its absolute accuracy. However, I'm certain it will be perfectly consistent, and that's all you really need to worry about when balancing the speakers.
I would recommend you perform the calibrations much as you have already done--measure the distances, and select crossovers for the mains. As for channel calibration, do this:
1) Set the L/R trims to 0dB. With the mic at your listening position, turn on the SSP's cal noise and measure L/R SPL. If they are not the same, tweak one or the other so they match. Note this SPL value.
2) Using the SSP's cal noise, set the rest of the main speakers to read the same SPL as in 1). Do the same for the sub, but this is only an approximate setting. You will adjust further with real programs.
3) Listen to familiar 2-ch music. Adjust the sub level trim (same menu as the noise cal--but do not activate the noise generator) to achieve a good spectral balance with the mains. You may find it needs to be different over time with different recordings, but eventually you will find a setting that's good most of the time. Then, for "on the fly" tweaks for certain recordings, call up the trim menu to adjust to taste.
