Hi! I know that Magnat is not a very well known brand in the UK, but I need some advice, and maybe someone there can help... The point is that I have a 5.1 setup at home, for almost a year already, and after playing around enough I know my system quite well. Still, there is something that I cannot understand... My center speaker is a MAgnat Vector 13, quite big btw, and rated as follows: Power 100/150 Watt freq range 36-35.000 Hz Impedanz: 4-8 Ohm Size 470 x 200 x 240 mm The other four are Magnat Motion 60, floorstanding with quite a deep bass (typical in Magnat), rated Power 120/240 Watt freq range 20-35.000 Hz Impedanz: 4-8 Ohm Now, how should I consider my center speaker? I mean, it is not a satellite kind of speaker, but when I set it to "small" I get a more robust, deep dialog (specially with "strong man voices"). Oh, my amp is a yamaha rx-v530, if that makes any influence.
