Hello, I am interested in purchasing a speaker system for my living room. Unfortunately, the room is not constructed in a manner that will lend itself to a full 5.1 surround sound system and I am therefore considering a 3.1 sound system. In other words, two towers, a center speaker, and a sub.
My room is about 19.5 feet by 17.5 feet. I will be using this system for 50% music, 50% movies.
So, some questions. Is a 3.1 sound system worth the cost of admission? Or would I be better off with a 2.1 system? Also, any suggestions on what to purchase for a solid system in this room would be much appreciated. At this point, I am wondering if two 5Ts, a 5c, and a 10d would do it — or should I step up to 6s and a 12d? What would be best for a solid music experience?
I think that a center channel is a good idea since it is a dedicated speaker for dialogue and everyone knows how frustrating it is to not be able to hear what the actors are saying when you are watching a movie. Of course there's nothing stopping you from starting out with a 2.1 system and seeing if that does the trick and then adding the center channel if you feel you aren't getting the dialogue clarity that you want.
As for 5T vs. 6T, the 6Ts are the best speakers we make in terms of music, since they offer the fullest midrange and broadest soundstage. So if you have the space and budget for them I would recommend going with them, they will not be overkill in a room of your size and if you are sitting less than 15 feet from the screen you can still pair them with the 5C as they are timbre matched.
In terms of the sub, the 10D should have no trouble filling the space, but if you move up to the 12D you will get more overall output and deeper bass by about 5 Hz. So if you really want to shake the walls down the 12D fits the bill, otherwise you should be fine with the 10D.
I hope that helps, but please let me know if you have other questions, thanks!
