The point is that the 703 has the same sound signature as the 705s in my case or 707s in your case, and are better in that respect than the 706 in that all drivers in all those speakers are in a vertical orientation and therefore have the same off axis response. Having 3 identical speakers, all vertical and all at ear height, up front is the ideal. That is what is used in movie theaters and high end home theaters with acoustically transparent screens. Having 3 vertical speakers with the same tweeter and midrange is a close 2nd, and better than a horizontal center channel in terms of generating a seamless sound field among the front 3 speakers. The only advantage of a horizontal center channel is that is not as tall and fits better under or over the TV, not because it is better sonically. It is not.Thats a thought.I wonder if the 703 has different sound signature to the 706C? I cant imagine it would be different but unless one has heard them both with amplified voices there is no way to tell.
