cS6 install guide
Glossary and Terms
Joist
Timber framed ceilings use joists to suspend ceiling
finishes, support flooring above and also to easily house
insulation/wiring/ventilation/services� As such, ceiling
voids may contain many hazardous or physically large
items which will need to be safely worked around� For
the sake of this installation guide, the term “joist” will
refer to a timber joist�
Plasterboard
Most plasterboard consists of a gypsum based core
with paper skins� Often referred to as drywall, sheet-
rock or wall-board, plasterboard comes in a variety
of compositions offering different performance
characteristics� While the plasterboard choice itself is
unlikely to impact installation of a cS6 subwoofer, it
is important to understand the entire ceiling build-
up before proceeding with installation� A maximum
distance from the subwoofer cabinet to the finished
ceiling surface of 100mm cannot be exceeded
(maximum 110mm port length, allowing for clearance
needed for brackets and screws etc�)� For information
on installations using specialist construction methods,
contact your Neostein dealer�
Port
cS6 subwoofer emits bass energy through a cylindrical
port� It uses a 6” driver in a fourth-order bandpass
configuration, which means that the driver is not
visibly exposed� As only the port opening is required
to penetrate the ceiling/wall, it allows for great bass
performance without the requirement for a large in-
room subwoofer or grille� The port opening can be
disguised using the supplied grille, or alternatively a
plaster-up-to flush mount grille is available separately�
The supplied port has 3 options for its location on the
cabinet and can be easily changed over to allow for
easier installation/cabinet orientation� The port cannot
be bent or substituted for a different length section of
pipe, however, it can be adjusted such that it protrudes
from the cabinet between 0mm-110mm� This level
adjustment ensures the port opening lines up with
the finished surface of the ceiling, rather than venting
directly into the ceiling cavity which may result in
unsatisfactory acoustic performance�
Amplification and Cabling
cS6 subwoofers are passive devices, and therefore
require external amplification in order to work� Most
audio amplifiers used for home-audio application will
work effectively, however care should be taken to ensure
that the amplifier can effectively handle a 4 Ohm load
and is not excessively over-powered for the subwoofer�
Integrated amplifiers, audio video receivers (AVR’s),
multi-room and multi-channel amplifiers all typically
work well, although if using an AV receiver you will
require an external power amplifier fed from the LFE/
SW line level output of the AVR� cS6 has an in-built filter
which removes excess high and low frequency energy
