Just installed my new IW63 In walls tonight. They replaced my Axiom QS8's in anticipation of immersive audio and to gel better with my mains which are also Tannoy. Wow, what a difference! I don't know if it was the sound diffusion of the QS8's that was prohibiting me from hearing everything in the audio track, but I was hearing stuff with my new Tannoys that I didn't hear with my Axioms. As per Dolby, I had my Axioms about 2 feet above me and just slightly behind the listening area. For the Tannoys, I installed them just slightly above ear height (the tweeter part) and exactly to the right and left of the main listening position. I thought for sure I would be able to localize the sound, but after calibrating with Audyssey on my old Onkyo 806, I was pleasantly surprised that it was not the case.
I threw in the beginning of Quantum of Solace which is my go-to demo disc for sound. The scene where Bond scoops the picture of Vesper I can hear the crowds in the background just before it cuts to the next scene. I never heard that before with my QS8's. I am really digging the monopoles and the clarity they bring! Granted, these are more expensive speakers, but I can honestly say based on what I heard tonight that I would definitely recommended good monopoles for surrounds as opposed to bipole or dipole speakers. I just can't wait to buy an Atmos/DTS:X pre-pro in the fall.
