Subject: Air Leak or Buzzing from Front Baffle

Some early versions of the Interlude IL60 loudspeaker may need an additonal gasket surrounding the tweeter. The original gasket is located behind and is affixed to the front baffle.

1)Remove the loudspeaker grille.

2)Extract the (8) grille cups from their cavities with a needle-nosed pliers or similar tool.

3)Remove the (8) Phillips screws holding the front baffle to the cabinet

4)Remove the front baffle; unplug the two faston connections to the tweeter terminals.

5)Apply a new rectangular gasket, Infinity part# 336050-003, on top of the present gasket, surrounding the tweeter. Final gasket(s) height should rise above the plastic “ledge” surrounding the tweeter.

6)Plug both faston connections back on the tweeter terminals.

7)Replace the front baffle, Phillips screws, grille cups, and front grille.
