4 subwoofer setup

I am thinking about redoing my home theater setup with 4 subwoofers 2 builtin 10" subwoofers mains and I was going to put two 10" subwoofer in the rear one for the right channel surround and back and one for the left channel surround and back. Any help would be great. Room size is 23 X 14 front mains are def tech 8060 rest of speakers are all def tech 1000's

You talk about left and right surround,

What kind of receiver do you have? Why 4 little one, what about just one or 2 big one? Just curious.

Problem with that setup is aren't necessarily filling in any of the sound gaps (e.g. missing low end frequencies) by using an additional two 10" sub, especially the same model. Ideally, you start with a larger, full range sub then fill in the gaps to make things 'smoother'. Read more here:

Plus, most of the end result is trial and error based on your (from what you have stated) fixed(?) positioning of the two front subwoofers, and overall room/listening environment including taste. Remember, adding more subs doesn't necessarily mean you match the current system by adding them near rear right/left surround.
