What speakers are actually playing for "Right", "RS", and "RS2"?
I had assumed that "Right" was the right speaker alone, and that "RS" was the right sub by itself. Not sure what "RS2" might be...perhaps a second sub on the right side?
However, all three of these speakers, "Right", "RS", and "RS2" are +21 dB at 22 Hz, so that does not seem right. Also, "RS" has 5 dB more output at 7 kHz than "Right", which rules out "RS" from being a subwoofer.
Even the center channel has massive output at 22 Hz, so it seems unlikely that it was measured independently of subwoofers.
Another possibility is that "RS" means "Right Surround" and that all speakers were measured with the same subwoofer active. Actually, that's the only reasonable explanation. But I still don't know what "RS2" and "LS2" are. Perhaps rear surround speakers in a 7.1 setup? There's an attached floorplan diagram, but it does not include any useful information about speaker placement or names.
Assuming that my last interpretation is correct, the biggest problem that I see is a large discrepancy between the left and right channels. This will have a negative effect on soundstage and imaging for stereo content, although it may not be that consequential for movies.

Differences are pretty dramatic below 80 Hz (less critical) and above 1.5 kHz (significant).
In the time domain, things are even more crazy.

I see something sort-of resembling a step response from the left channel, but the right channel is not showing a recognizable step response. Ideally, these two curves should match each other closely and look something like this (recent measurement at a friend's house with 2-way Paradigm monitors):

Here's the amplitude response of the left and right channels from the same system:

Note: these measurements were taken with no subwoofer...just a simple 2.0 system. But I hope this gives you an idea of the kind of response you're shooting for. Mainly tighter correlation between left and right channels.
