A:Answer5.1 surround consists of Two fronts (R/L), Two Rear (R/L) and a Center Channel = 5 Speakers. The "point 1" is the subwoofer. Now that we are on the same page on what a 5,1 config consists of, the Two speakers up front would be primary Right and Left. If you currently have a 5.1 set-up and place these up front up top, then yes these will work great as front heights. This would essentially move you to a 5,2,1 solution at that point. If you are asking if these speakers would work for front left and front right - the answer is they will produce sound, no they are not idea as Front R/L Main. Yes on heights, no for mains. Hope that helps. Floor standing speakers are going to be the best option for front left and right mains, solid bookshelfs could be utilized as well with a good subwoofer with front mains. These speakers do not handle the range or the wattage a solid set of FS speakers would handle and be able to produce. These speakers will work great for rear surrounds, rear height surround, side surround, or Atmos height front or rear. These are not good for front main speakers.
A:AnswerThey're designed so you don't have to mount anything in the ceiling. They can be mounted high on the wall or lay completely flat on tower speakers. They come with rubber footings so theres never any full contact between the speakers and wall or tower speakers
A:AnswerThey will produce audio, but it will only be a surround channel. In these cases, you should hang them off the wall as opposed to on top of the tower speakers as Atmos.
A:Answer2 sets of terminals on a speaker indicate they can be bi-wired to separate frequencies that go to the woofer(s) and the tweeter(s) from an amplifier that is configured for it or two separate amplifiers. These two sets of terminals on the speaker should be bridged together unless you are going to bi-wire them from the amp(s). Speakers that already have the Atmos speaker built into them (two sets of speakers in one cabinet) will also have two sets of terminals that are not bridged with each set being a separate channel to connect from the receiver.
A:AnswerI believe these have a switch built in to use as surround or height speakers. Changes frequency crossover point. However these speakers are physically built with the proper speaker angle for Atmos performance. ( angled up) Your speaker would have to be placed to accommodate that angle and adjust speaker face perpendicular to floor to sound best.
A:AnswerI use these as surround rear hanging on the wall and Klipsch ceiling mounted speakers for Atmos right over my head just in front of my seat angled back. The speakers have an adjustable tweeter. This works really well with my vaulted ceiling with 5.2.4.
A:AnswerI would say yes. They have a switch to turn off the Dolby crossover intended to make the reflection work. In a "direct" situation with the switch in the surround mode, I imagine they will work great, especially to match other Klipsch. If you have other types of speakers consider the SVS too.
