8. und quality and reliability of FORCE loudspeakers will be realized in virtually any sealed vented bass reflex horn or open backed enclosure VENTED ENCLOSURES The most extended lowest distortion and best controlled bass performance is usually realized in properly designed vented enciosures In such designs the vent or port actually reproduces the lowest octave or so of bass response The vent is driven to full acoustic Output by a relatively smail motion of the speaker cone itself acting through the air contained within the enclosure The excursion of the speaker at these frequencies is much reduced compared to sealed or open backed enciosures directly reducing harmonic distortion and the possibility of speaker bottoming INSTALLATION FORCE speakers may be front or rear mounted although front mounting is pre ferred because of convenience For simple front mounting the convenient SMH 1 mounting accessory is recommended Complete mounting instructions are included with the SMH 1 Instructions for standard front mounting are given below It s important that recommended baffle openings and mounting hole locat ons be followed as Stated in the specifications table For front mounting mark baffle opening and screw locations on the blank panel first Drill the screw holes before cutting the large baffle opening If 4 20 screws are used four screws are sufficient for secure mounting of the speaker T nuts ar
