I just wanted to have your input on having the same speaker for all your channels.
I personally am a big fan of this setup, as it just gives the most natural blend between the channels and every speaker is basically equally important.
You will need to have the space, of course, to place them correctly, with proper distances and angles.
But if you do, you get a great bubble of sound.
We have had this review with 5x 1723 Bookshelf S, and I am right now thinking about doing the same thing in my home theater.
