Hi Bluray,

The vertical orientation of the front and rear sides of the speaker provide all the strenght to keep the VP180 in perferct shape for ever even if it was supported only at each end.

The precise dimensions in mm are :
length : 1000 (39.37")
depth : 415.670 (16.36")(without the magnetic grille installed)
Height in front : 232.651 (9.159")
Height in the back : 180.893 (7.122")
