A single pair of 1400 SR's can replicate the sound of the large array of surround speakers found in the best commercial movie theaters. Set for Dipole, they create a diffuse sound field that is virtually impossible to pinpoint by ear, enveloping the listening room in realistic three-dimensional sound effects. Set to Bipole, they deliver a more precisely localizable sound pattern that can be very dramatic with high-impact popular music. The listener can choose the preferred effect with the flick of a switch. The 1400 SR-z's small size makes it particularly appropriate for use as 'height' speakers in the very newest home theater systems.
