soooo...my room is currently setup according to the attached diagram. the green blocks are klipsch speakers, the blue blobs are an L shaped couch and a chair, and the red box is a klipsch sub 10 sub.
the room measures 18 feet long by 11 feet wide, and my listening position is exactly equidistant between the side and rear surrounds, and is just forward of the halfway line between the front stage and the rear surrounds. the drawing is not exactly to scale, but you'll get the gist of it
my dilemma is this...i have been thinking for a while about adding a 2nd sub, as i have been living here for almost a year and a half and havent had a single noise complaint yet. this tells me i am not being loud enough.
i'm wondering if i would be better off adding another 10" sub, or selling my 10" and buying a larger 12"
im looking for opinions from those with multi sub setups...what would you think would be best? i have heard stories about running into phase problems and null spots and stuff with multi sub setups. do you think the SPL advantage of 2 10" subs would be worth the extra hassle? would the simplicity of having one 12" sub that is more powerful outweigh the setup problems of positioning two subs? do you think having a mismatched pair, (one 10" one 12" in the same room would cause problems?
if i did go with the 2 sub setup, any ideas where the optimal place to put the 2nd one would be?
