The KH 805 subwoofer

Thank you for purchasing a Neumann subwoofer . Neumann subwoofers are designed to com-
plement Neumann’s extensive range of monitors . They can be used in music, broadcast, and 
post production studios for tracking, mixing, mastering, and home recording . They can be 
positioned next to a wall or flush mounted into a wall, and can be mixed freely in multi-chan-
nel systems with other loudspeakers and subwoofers from the Neumann Studio Monitor Sys-
tems range .
The built-in 2 .1 / 0 .1 Bass Manager can be used in many ways as there are four routing modes 
to ensure maximum flexibility when using the subwoofer - see “Uses” below . Fourth order 
crossovers and flexible acoustical controls allow for seamless system integration and the bass 
management function can be remotely controlled .
State-of-the-art circuitry design and the specially developped long excursion bass driver have 
been used to ensure the most accurate sound reproduction possible . Neumann products are 
designed for longevity so we hope you enjoy many happy years of using this product .
