We bought the Beam & Sub Mini for our 77" LG TV in a medium sized family room. We chose the Beam over the ARC because we did not need an overpowering sound stage & the Beam fits nicely under our tv without blocking the screen where the ARC would block our view. We use a fine furniture stand for our TV & Beam as we have windows that prevent wall mountings and we did not want to place the soundbar on a lower shelf. The Beam works great with our large screen; not too small. Great addition to our viewing and listening pleasure. We will be adding a pair on Era 100 speakers soon.
Pros: Easy To Setup, Easy to use, Speech enhancement, Superior Sound, Versatile, Wireless Surround Sound
