.www.velodyne.com SC-IW Installation Manual
The SC-IW (In-Wall) subwoofer can be installed in a variety of locations and positions in any given
installation. Although this product is extremely versatile and flexible in its uses, it has been
specifically designed for two major applications - New Construction Installations and Retro-Fit
Installations in structures made of traditional 2x4 studs with 16 inch spacing, on-center.
This document provides the detailed process for properly installing the SC-IW into a wall. The
SC-IW is designed to be powered by the SC-1250 subwoofer amplifier. For maxiumum
performance, it is strongly recommended that only the SC-1250 be used to power the SC-IW.
The user’s manual for the SC-1250 subwoofer amplifier provides the details on connectivity and
proper configuration of the SC-IW after installation.
Driver Technology
The SC-IW subwoofer utilizes new and innovative patent-pending driver technology that has been
created specifically for the custom installation market. The SC-IW driver was specially designed
to maximize in-wall subwoofer performance while significantly reducing wall vibration. The driver
uses "dual tandem spider design" along with a propriety neodymium motor structure providing
an extremely long-throw driver capable of producing very high sound pressure levels. Below is
across section of the SC-IW driver.
Cabinet Technology
Complimenting the cutting edge technology in the SC-IW driver is the cabinet, again specially
designed for in-wall installations. The SC-IW cabinet wall utilizes a propriety multilayer "sandwich"
material consisting of two 1.0 mm aluminum plates surrounding 2.5 mm of medium density
fiberboard (MDF) which is laminated under high pressure to create an extremely rigid cabinet
design that has the density and performance of traditional high end cabinets utilizing 3/4 or 1
inch MDF.

The SC-IW consists of two cabinets — the “driver module” and the “back box.” (a.k.a. the
“Enclosure”). Unlike other in-wall products where a back box may be optional, the SC-IW
requires both enclosures, unaltered, for every installation. In new construction situations, the
back box is in installed first (for example, at the framing or rough out stage), and the driver
module is installed later in the trim out stage. In retrofit situations both boxes are typically
installed together.
The driver module assembly is shown below. It uses a unique bracing system in that the driver
acts as the "internal bracing structure" for the speaker enclosure.
The in-wall back box contains internal bracing to minimize cabinet flex and wall vibration.
The driver module and the back box areconnected through two rubber conduits, sealed with
supplied hose clamps. This linking system provides the installer the flexibility to either install the
two boxes together in the wall or separately prior to installation.
The SC-IW comes in two completely separate cartons — the SC-IWBB (Back Box) and the
SC-IWDVR (Driver).
Parts included with the SC-IWBB rough install kit:
•In-wall back box - Qty 1
•Mudring for "retro fit" installation - Qty 1
•Installation manual - Qty 1
•Installation hardware
Parts included with the SC-IWDVR driver module:
•SC-IW driver module - Qty 1
•Clamp ring - Qty 2
•Standard grille - Qty 1
•Designer grille - Qty 1
•Hardware
•Installation manual - Qty 1
You must first decide how the SC-IW is to be installed — whether new or retrofit installation,
and whether you are using the standard or designer grille. Remember that in all cases the grille
can be painted to match the room’s de´cor.
Consider the following information when deciding how the SC-IW will be installed.

Standard Benefits: Benefits:
Grille •Allows pre-installation of the back box Provides easiest servicing for the driver
at minimal risk and expense

•No risk to the subwoofer during this installation
drywall/paint/finish processes
See page 4 for a description of
this installation
Designer Benefits: Benefits:
Grille •Provides the smallest grille available Provides the smallest grille available
Considerations:
•Must install both back box and driver See page 25 for a description of
cabinet at frame out stage — higher risk this installation
of theft or damage to the subwoofer
•Difficult to service driver as drywall must
be removed to remove driver module

Note: This installation process assumes that the installer has access to the open framed 2x4
studded wall with 16 inch spacing. In the event that the stud spacing is larger, an additional
2x4 or other spacer can be used to fill the space between the SC-IW back box and the
neighboring stud.
Step 1 - Install Mudring
Unpack the first carton (SC-IWBB) and place the contents on the floor. Remove the mudring
from the packaging. At this time the decision needs to be made about which direction the woofer
will fire (up or down) and therefore where the grille will be located on the wall. Typically the woofer
will fire downwards and the grille will be located near the floor. (Remember to consider
baseboards and other trim work that might be used on the house in this case.) Once you have
decided where to place the grille, staple the mudring to the studs as shown in figure 1.
Align mud
ring to line
on the
back box.
Figure 1: Install Mudring - The back box is used for reference position only — it is installed in the next step.
