I buy so many things from Amazon that I also subscribe to the Amazon Prime $79/yr, which gets me free 2-day shipping Prime + the free Prime Video Streaming on my Panasonic BD player.
You won't find many hardcore speaker measurements on speakers in this price range, but Soundstage/Canadian NRC measured the P162. Accurate flat on-axis and off-axis FR, if you like accurate sound and all.
I've listened to the P163 as well. Very clear sounding. At $85 each, they are best bang for the buck IMO.
