sawm40 subs coupled with 2 more sawm20 subs? beneficial or unnecessary? (1 Viewer)

i currently have 2 sawm40 12" sony subs

and my local bb has the sawm20 subs on sale clearance, im wondeirng whether i should buy the sawm 20 8" subs since theyre so cheap

my room is strange, there are a lot of dead spots in my room, even with the 12 inch subs you dont hear it in my room unless youre within a few feet of direct fire.

my room is about 15'x15'

its small yet bass dissipates very quickly in it. its pretty empty in my room.

im wondering if i should get two more 8" subs to help increase the size of the sweet spot?

since i dont know anything about cancelation and all that technical mumbo jumbo, what should i do?

will getting 2 more 8" subs help strengthen the bass? or am i being too greedy?

More subs???

You would probably get better results using only 1 sub. Bass frequencies are very hard to control. With 2 bass sources, you are most likely getting cancelations from each other. Aim 2 subs right at each other and the bass waves will collide in the middle canceling each other, therefor producing no sound. Now that that idea into a wierd shaped room with bass wave bouncing around many different was and they are going to collide everywhere.
Try using just one sub. Spend some time trying it in many different locations to see which sounds best. Chances are that if you get 1 sub in the proper location it will sound better than 2 or more subs.

hi myo
brian is right, one sub should be perfect, adding more subs can add cancellation issues, the two sony 12"subs calibrated properly should be more than sufficient.
