There's a good article on Audioholics here: Optimum Room Locations for Subwoofers An Analysis.\n\nThe author ran simulations on different room sizes, listener positions and sub placements to see what works best. The article concludes with:\n\nThe biggest single takeaway from all of this is that rules of thumb about which subwoofer configurations work best are of limited use if you don’t take seating configuration and room dimensions into account. SO, how can this be done? How can these simulation results be of practical use? If you are designing a room and have some latitude as to dimensions, seating and subwoofer configurations, you should be able to look at the data and find a combination which best fits your goals gives the best possible results. If one or two of these variables are fixed, you can make the best selection for the remaining one(s).\n\nThe article seems to suggest you can look at the library data to pick out the result relevant to your own situation, but unless I'm being blind the data is no longer available? And the paper costs money to download.\n\nIs there a way to plug your own situation in to these simulation results?\n\nHas anyone done similar studies and simulations with other sub placements? In particular, non-symmetrical positions like 1 sub in a front corner, the other sub 1\/4 of the length along the back wall?
