95% of my time is spent watching movies, sports and TV shows (5-10% music).
For reference, my set up would be either 1 or 2 SVS PB-1000 (already own 1 sub now) and either a pair of Q acoustics or Martin Logan bookshelfs or towers. The subs, whether 1 or two would be placed to the left and right of the TV facing my main listening position.
Room is big open concept room with kitchen behind main listening position and high ceilings
Would you go dual subs and bookshelfs or one sub and towers with the choices I have (SVS, Q Acoustics, Martin Logan)
Just so you understand, this is actually two separate questions:
Question 1: Bookshelves or Towers?
a) How far away are you sitting from the speakers?
b) How capable of a bookshelf?
In general, as long as the bookshelf can play "cleanly" down to 60hz minimum (this is for the standard 80hz crossover, you don't want the speaker distorting before or at the roll off point) then you need to consider your seating distance. As a "general" point of reference, 11-13' is a good transition point for deciding between Bookshelf or Tower, anything farther than 13' or so, you should probably go Towers. (If you're using less capable bookshelves, figure subtracting 2' from that reference distance)
Question 2: One Sub or Two?
In an enclosed room, this question needs consideration for 3 concerns, how many seats do you care about?, placement options?, building enough pressure.
But, you don't have an enclosed space, and you sound limited in placement options, so most of this is out the window. (plus with your space and PB1000' s, you'd probably need 6 minimum, for any real pressure)
So, if you go with bookshelves, get two, if you need towers, just plan on a second down the road. But if there's any way you could get it or them closer to your seating (maybe flanking the seats as end tables) do so, it may provide some extra tactile sensation, to help with the lack of pressure.
