NSurface : [stk]
Dfloor : [cm]
Drear : [cm]
Dside : [cm]

NSurface is the number of reflecting surfaces near the speaker source and can take one of three values (1, 2, 3):

NSurface = 1 means the speaker is close to one reflecting surface (e.g. on the floor).
NSurface = 2 means the speaker is close to two reflecting surfaces (e.g. on the floor close to rear wall).
NSurface = 3 means the speaker is close to three reflecting surfaces (e.g. in a corner)

The source location will typically be the (acoustic) center of the bass driver relative to the reflecting surface(s).

Dfloor is the distance from the source to the first reflecting surface (centimeters)
Drear is the distance from the source to the second reflecting surface (centimeters - only applicable if NSurface > 1)
Dside is the distance from the source to the third reflecting surface (centimeters - only applicable if NSurface = 3).
