I use two JL f110's for my stereo where they play in the background to fill in the sound. I had one f113 in my room, but for better imaging and the small roll they play in my 11x25 foot room the f110 (for the price) is all I need.
For home theater where a sub plays a larger part you need the f113 for better impact and to shake the walls.
