Introduction

Welcome to the Sub RCC in-wall subwoofer, and thank you for choosing a Dynaudio Custom Install product.

The Sub RCC is designed to provide concealed low frequency enhancement while at the same time incorporating features and facilities designed to ease installation.

This manual describes the installation of the Sub RCC. The manual begins by illustrating the contents of the carton and continues with sections covering selection of subwoofer positions, subwoofer preparation and subwoofer installation.

If this is your first time working with a Sub RCC subwoofer, or if you have not done so for a while, we recommend that you read this manual before you begin.

Note

The Dynaudio Custom Install Sub RCC is designed to provide very high quality low frequency enhancement in custom installations where speakers are required to be concealed within room boundaries. The Sub RCC incorporates horizontally opposed drivers that ensures minimal vibrational energy is transmitted to the room structure.

The Sub RCC is primarily intended to be installed within drywall/plasterboard walls however it can in some circumstances be installed within ceilings. Each Sub RCC requires a dedicated AudioControl S500G4 power amplifier that incorporates the appropriate equalisation.

The Sub RCC is uniquely simple to install in either existing (retro-fit) or newly constructed (pre-fit) drywall/plasterboard walls. If a Sub RCC is to be installed within a ceiling, this must only be carried out in either a newly constructed ceiling or following removal of the plasterboard around the install location in order that the Sub RCC can be secured to the ceiling joists.

The Sub RCC requires appropriate mechanical configuration depending on its retro-fit or pre-fit installation mode. Configuration is described in the following Preparation section of this manual.

These instructions broadly assume that for retro-fit installation, appropriate cables are in place, or that for pre-fit installation cables will be fitted at the same time as the subwoofer.

Carton Contents

The In-Wall Sub carton contents is illustrated in Diagram 1 below. Within each carton can be found:

Subwoofer Positioning

The appropriate location for Sub RCC in-wall subwoofers within the installation space will depend on the specific audio application. Guidelines for different applications are described in the following sections and illustrated in the accompanying diagrams.

Generally, locating any subwoofer closer to room corners will increase the volume of bass it generates. Although the extra bass can be compensated for by reducing the volume level of the subwoofer relative to the rest of the system, corner locations can also result in uneven bass response at the listening position. In most cases, subwoofers are best located below head height when sitting.

Stereo Audio

A single Sub RCC used for low frequency enhancement in stereo audio systems should ideally be located centrally between the left and right speakers but asymmetrically with respect to the side walls of the room. If a location between the speakers is not practical, a location adjacent to one of the speakers can also be feasible, however it is important that the Sub RCC is not located too close to a room corner.

If twin (left and right) Sub RCC subwoofers are to be used with a stereo audio system, each one should be located as close as possible to its respective main (left or right) speaker. If this is not practical, the two subwoofers should be located close together either between the front left and right speakers or adjacent to one.

Stereo audio system subwoofer positioning is illustrated in Diagram 2 below.

Home Theatre Audio

An Sub RCC subwoofer used for the low frequency effects channel in a home theatre system is best located between the left and right channel speakers or adjacent to one of them. If these locations are not practical the Sub RCC can be located along one of the side walls of the listening room, however it should always be located in front of the listening area.

Home theatre system subwoofer positioning is illustrated in Diagram 3 below.

Preparation

Pre-fit or Retro-fit

The Sub RCC is configurable for installation in either newly constructed (pre-fit) or existing (retro-fit) drywall/plasterboard walls.

Note

In addition to wall installation, the Sub RCC can potentially be installed in newly constructed ceilings (pre-fit). It is NOT suitable for retro-fit ceiling installation. Follow the pre-fit in-wall installation instructions in the case of ceiling installation.

Note

Pre-fit Sub RCC installation can also include existing walls from which the plasterboard has been removed.

As shipped, the Sub RCC is configured in retro-fit mode and can be installed in existing drywall/plasterboard walls without modification. If a Sub RCC is to be installed in the this manner, the following section of this manual may be disregarded.

If a Sub RCC is to be installed in pre-fit mode in a newly constructed drywall/plasterboard wall (i.e. before the plasterboard is fitted) it must be configured appropriately. Pre-fit configuration is described in the following section.

Diagram 4. Retro-fit Adaptor Plate Removal

To attach the Pre-fit Mounting Brackets identify the eight attachment screw holes in the sides of the subwoofer body and the eight M6 x 15 mm screws supplied. Attach the brackets using the screws as illustrated in Diagram 5. Do not fully tighten the screws at this stage.

Note

Pre-fit Mounting Bracket screw holes are located on the end and side panels of the subwoofer. Either option may be used depending on the requirements of the installation.

Sub RCC Subwoofer Installation

Note

These installation instructions broadly assume that subwoofer cable is pre-installed.

Retro-fit Installation

To install a Sub RCC subwoofer in an existing drywall/plasterboard wall, proceed as described in the following paragraphs and accompanying diagrams:

Note

In order to reduce the possibility of audible wall vibration it may be prudent to apply a bead of adhesive mastic between the wall studs and the drywall (plasterboard) in the vicinity of the subwoofer.

Note

If subwoofer cable is not already installed it should be done at this stage. It is possible that access will be required through the opposite side of the wall to route the cable. Use low resistance subwoofer cable with clear polarity marking on its insulation. Low resistance is especially important if the length of cable from amplifier to subwoofer exceeds 5 metres. Your local Dynaudio retailer or distributor will be able to offer advice on subwoofer cable selection if required.

Note

In cases where the subwoofer is installed within a nominal 16 inch (496 mm) stud pitch wall, additional installation security can be obtained by using the six supplied Ø5 x 45 mm wood screws. The wood screws should be inserted at a 45° angle in the six subwoofer front flange holes and tightened through the plasterboard to engage with the stud woodwork beneath.

With the subwoofer connected and secured in the wall, installation is completed by fitting the grille. The grille is secured magnetically and requires no more than placing into position.

Pre-fit Installation

Note

If a Sub RCC is to be used in a “pre-fit” installation it will require appropriate configuration. Pre-fit configuration is described and illustrated in the Preparation section of this manual.

To install a Sub RCC subwoofer in a newly constructed drywall/plasterboard wall, or in an existing wall from which the plasterboard has been removed, proceed as described in the following paragraphs and accompanying diagrams:

It is also important that the Sub RCC grille is trial fitted before the plasterboard is secured in place. This is to ensure that the magnet strength is adequate to retain the grille and will depend on both the thickness of the plasterboard and how deep into the wall the subwoofer is located. If greater magnet strength is required for secure grille retention, two or four of the supplied magnet strips can be fitted to the long sides of the Sub RCC output slot.

Note

If the wall is to be painted following Sub RCC installation, the subwoofer must be protected from paint ingress. If a Sub RCC grille is to be painted, this should be done before is is fitted.
