I have heard this from others, but I am not seeing the logic behind it.
I my case I have a pair of towers which are great and would be considered Bright Speakers.
My second pair which I also enjoy and would be considered rock & roll speakers with stronger base.
My thinking was by adding a second sound source was the equivalent of some speaker systems with multiple drivers in one box. I could see that maybe the drivers could be out of sync theoretically which could negatively affect the sound. But just the adding of more drivers playing from the same source to me should not be a negative.
The good news is the cost to try is nominal as I already have everything except the splitters
The room will be larger 15X25 so thought the added sound sources would be a benefit.
At this time I am gathering info as we will be moving to a new location in December
Thanks agin for your thoughts
