A:AnswerThey mount without a bracket. The speaker itself has mounting arms that extend when screwed in and hold a tight placement against the drywall. It works great. I installed 8 myself.
A:AnswerKlipsch offers both in ceiling (like these) and in wall options for most every series of architectural speaker they make. I cant think of a good reason to use an in ceiling in the wall or vice versa unless the space required something out of the norm.
A:AnswerThis will defenitely rock your house. I had 2 out of 4 hooked up in my living room with power coming from a Pioneer VSX-1123 and it rocked my house. With 5 of them the 14Ft ceiling is no match. Most importantly to get the best quality sound will depend on the source and power delivered to them. Weak input means weak output. When properly powered they will rock all night long.
A:AnswerI have these setup as rear speakers in a 26x26(ish) sized room and they do the trick but work best when your seated on the couch in front of the TV. If you're using them that way, the pair is fine. If you're using them as stereo speakers for music, follow your heart and put as many as you want (as long as your receiver can handle the ohms).
A:AnswerThere are only 2 screens that they come in, square or round magnetic covers. if you don't put the covers on, that would show the black speakers.
A:AnswerBuy a receiver. I have this (http://www.bestbuy.com/site/yamaha-650w-5-1-ch-4k-ultra-hd-and-3d-pass-through-a-v-home-theater-receiver-black/6078137.p?id=1219658502326&skuId=6078137) which is really good . you need to connect the speakers with the receiver and the blueray player to your tv .. Then you can connect your tv to the receiver via optical/HDMI cable ....
