Apropos of (almost) nothing -- due to the extreme kindness of a fellow Polk Audio fan on over t' Club Polk, I have a pair of the S20 loudspeakers here. They are very pleasant to listen to if a bit "hifi" sounding. "Hifi" in quotes as opposed to, you know,
hifi... somewhat zingy treble (which actually is a good fit for my now-elderly auditory processing system) and a just a wee little bit warm/
phat sounding in the midbass.
I find myself using them often for "general purpose" listening (NPR
via OTA FM, videoconferences, background music listening).
I was surprised by their large and somewhat squat form factor compared to the R200 (S20 to the left, R200 to the right in photo above). I had hoped to use them with our (seldom used) TV, but they are too large for the space available on top of a large-ish cherry "entertainment center" cabinet.
It would be interesting to compare them to the current "ES" morph.
