I'll add my 2 cents on the Polk atriums! I got a pair of the Atrium 6 and they are insanely loud and crystal clear. Had patriotic music pumping through them last night while the neighborhood set off their fireworks and pretty sure everyone could hear them with the fireworks
got a 100x2 watt amp and a Polk audio dts play-fi receiver to go with the rest of my house system. Was between the polls and the klipsh ones that are comparable and ended up with Polk's and am super happy. They are huge though, was not expecting them to be that big.
Mounted on the end of our pavilion under the overhang a bit pointed towards the pool.
