Can you give more detail about your equipment, cables, etc. and also your room dimensions and setup? And no, putting another pair of speakers behind your front pair to achieve depth of stage or anything else is not a good idea. It would be an absolute mess.
Improving 2- Channel Soundstage
I don't know if I'm asking my question in the right topic area but I figured folks with HT experience may be able to help. It may also sound like an odd/stupid question so please bear with me. I'm a 2-channel/stereo audio guy and I'm trying to improve the soundstage in my listening experience. Has anyone tried a set up where you put another pair of (smaller) speakers between the (front) 2-channel speakers, closer together and pushed further back behind the two main speakers, sort of like deeper into the soundstage. I suppose using a "center" speaker/channel is another option. Now, would using the main speakers as front and the two behind them as rear/surround or cenetr speakers and apply an EQ such as "Hall" or "Concert" help with creating a deeper soundstage? This is of course assuming the source material is just 2-channel audio and the EQ choices are based on what the HT receiver can offer. Thanks.
