Installation Installation Optional Feet Two sets of optional feet (four Tiptoes and four Glides) are supplied with the LS340 Loudspeaker System. To prevent crushing carpet use the Tiptoe spikes; to protect non-carpeted flooring use the chrome Glides. Both the Glides and Tiptoes have a threaded shaft and locking nut that screw into the tapped holes in the bottom of the LS340s base rails. The feet can be independently adjusted to compensate for uneven flooring or to aim the loudspeakers upward or downward.
