Anyway, I do agree that the LRS are seriously bass deficient, at least as far as I've been able to determine in my listening room. I think this problem has been aggravated by placing them on off-the-floor stands (as some of the comments on that forum suggest will be the case) and maybe tomorrow I'll remove the stands and re-install the manufacturer supplied ones and re-assess.
As for "virtually unlistenable", I don't agree with that conclusion. Allowing for the bass issue (without sub-woofers), I'm generally content with the LRS.
I'm interested in reading Audiogon comments from technically sophisticated reviewers on that Audio Science thread.
