Do you really want your speakers set up as pairs of stereo speakers? The indoor answer to that question might be an obvious Yes!, but, because of the different environment and more active nature of outdoor listening, the outdoor answer might actually be Hmmm, maybe it would be better to have all the speakers playing in mono.
I have two patio areas. One has a pair of stereo speakers while the other has two speakers each playing in mono. I much prefer the mono setup because the way we listen to music outside pretty much negates the importance of things like imaging, soundstage, sweet spot, etc. (In my situation, even if we are calmly listening in a fairly centered position, more often than not, our backs turned toward the speakers anyway.) Rather, it's more important to hear all of the music equally well from wherever you and everyone else happens to be sitting, standing or moving about. The mono approach also affords much greater flexibility in placement of the speakers.
Whichever setup you decide on, I highly recommend these Polk Atrium 65SDI
(6½ woofer). Until Polk's new line of outdoor speakers was released last year, the 65SDIs sold for $350 each, so, $110 w/free shipping is an almost insanely great price. I have these and just love them. When I was shopping around, the three best speakers that I auditioned (like you, I auditioned them indoors.) were the Boston Acoustics Voyager 6, Klipsh AW-650 and the Polk Atrium 65SDI. I really liked all three; thought they sounded pretty much equally good; and, thought that I'd be very happy with any of the three. I went with the Polk Atrium 65SDI because of the extra flexibility offered by their Dual Input option and because of their reduced pricing. (They work equally well as regular stereo pairs or as Dual Input mono pairs so there's absolutely no downside.) As I said, I just love them. Big, beautiful, detailed sound. - Hey, at this price you just can't go wrong. (Maybe not many left though?) I bet they're at least
as good as any of the speakers on your list. Here is Polk's description of the 65sdi.
One consideration > Using the Dual Input method requires that both right and left channels be fed to each speaker, therefore it doubles the number of amplifier channels needed. - Each speaker is driven as if it were a stereo pair.
*On the plus side though, if you do decide to go with mono sound, you won't have to fool around with the whole series vs parallel vs parallel series wiring thing..
