Klipsch speakers are bright to most ears (tiring) and I don't care for them. I checked the specs on the Aperions, and if installed properly should do a good job, with a subwoofer. All in walls will need a subwoofer for HT duty, and music too, depending on taste in my opinion.
BUT WAIT! You only get to install these once, so lets get this right the first time. Look at
Speakercraft. MazerSteven has these in his house I think. But he recommends others in another post, be right back.
Triad And
Snell are a little higher on the food chain. Hope this helps
