IW200 SUBWOOFER Sub In-Wall Woofer Enclosure Installation Guide
Introduction
This woofer and enclosure were carefully engineered to deliver well-defined bass, while remaining virtually
invisible in a room. The enclosure is designed for installation during new construction or major remodel jobs to fit
between framing studs placed on 16” centers. The enclosure dimensions are 72” high X 14” wide X 3 ½ “ deep.
The woofer enclosure is for a dual 8” mono woofer system design that will be powered by the P200 subwoofer
amplifier, so during pre-wire, you will want to run a pair of wires from your source location to the woofer location.
Selecting the Woofer Location
When selecting a location to install the woofer, it is recommended the woofer be located near the left and right
front speakers. Avoid placing the woofer on an opposite wall whenever possible. Room placement will affect the
output of the woofer. It is recommended that the woofer be placed near the floor or ceiling and close to a side
wall. Avoid placing the woofer in the center of the wall or the center of the room when possible.
Getting Started
Before beginning your installation, it is recommended that you measure the bay (the space between studs) you
intend to install the woofer enclosure. Although 16” centers are the standard for framing construction, you will
likely find many variations. For the simplest installation and best results, select a bay that is clear of any
obstructions like electrical wiring, gas or water pipes. The woofer enclosure is intended to rest on the bottom plate
between vertical studs. The bottom (toe) plate is the 2” X 4” stud lying on the floor, to which the vertical studs
supporting the wallboard are nailed. The height of the actual woofer in the enclosure was selected to allow the
woofer-mounting flange used to mount the subwoofer system, to provide adequate clearance for decorative base
molding up to 6” wide. Note: IN custom homes, the base molding may be wider than 6” requiring a cutout around
the mounting flange. You may wish to raise the woofer enclosure slightly above the bottom plate. Consult the
general contractor if this is a concern.
Step 1
Open each end of the carton and slide the woofer enclosure out of the carton. Note: Do NOT pull the woofer
enclosure from the packing carton using the speaker wires as a handle.
Step 2
Once the enclosure is placed between the framing, run screws through the stud and into the cabinet. We suggest
no less then 6 per side. This will retain the woofer enclosure in place and prevent it from vibrating against the
studs. The wood baffle over the opening in the enclosure is to be used as a guide for cutting a through hole in the
drywall. This needs to be removed after the drywall is up and when you are ready to install the IW 200 Sub flange
and driver assembly into the enclosure.
Step 3
Once the enclosure is in place you are ready to connect the speaker leads to the amplifier leads. The wire in the
enclosure is 16 Gauge plenum rated UL approved stranded copper wire. You may make connections a number of
ways including butt-connectors, wire nuts, electrical tape and solder. Soldered connections with heat-shrink
insulation, is the recommend way to splice the amplifier and woofer wires. Please note the (+) terminals are
indicated with a red wire. Note: Low voltage electrical codes differ by state. Check your local low voltage code
before selecting a method of wire splicing.
IW200 Subwoofer Installation Guide
Thank you for purchasing the Phase Technology IW 200 Sub high definition in-wall subwoofer speaker system. The
mounting frame made of extruded aluminum has a self-aligning clamping system to secure the flange assembly to the
drywall. This patented design simplifies installation and reduces unwanted wall vibration resulting in improved
performance and definition.
Step 1
Carefully remove the speaker baffle from the aluminum frame assembly and set aside. Remove the flange assembly from
the packing carton. The flange assembly must make a good seal to insure maximum performance. You will find two Lshaped foam gasket pieces in the bottom of the carton. Peel the removable tape from the gasket and stick the adhesive
side to the backside of the flange. Upon installation of the flange assembly gasket will contact the front wall surface to
form an airtight seal.
Step 2
When you remove the flange assembly from the packing carton, you will notice the screws used to retain the clamp
assembly are fully extended. To place the flange assembly into the wall IW200 enclosure box push the clamp assemblies
toward the center of the flange opening; the holes in the flange will allow the mounting screws to tilt toward the center
opening enough to insert the flange assembly into the wall and into the box. Insert the right side into the wall cutout and
slide the complete assembly to the right. This will enable you to then fit the left side clamp assembly into the cutout.
Center the entire assembly in the opening.
Step 3
Pinch the self-aligning clamp assembly inside the wall until it contacts the backside of the enclosure baffle.
This will force the three retaining screws to protrude from the front of the flange. Continue to hold the clamp
with one hand and use the electric screwdriver to tighten the center screw of the flange. Once snug, repeat the
procedure on the other clamp assembly. Verify the mounting frame is correctly aligned in the opening. Make
any necessary adjustments then tighten the remaining screws until the frame is snug and securely clamping the
wallboard. Avoid over-tightening the screws.
Step 4
You are now ready to install the speaker baffle into the mounting flange. Insert the positive and negative conductors of
your speaker wire into the screw terminal using care to properly connect the + & - leads correctly. Using a 3/32” standard
screwdriver, tighten the screws in the connector to secure the wire.
Step 5
Six screws and washers are supplied to secure the baffle to the flange. Hold the baffle in position until you have at least
two screws properly secured.
Step 9
Insert the grill assembly by applying light pressure at each corner of the grill until flush with the flange assembly. A paint
shield is supplied with each grill to protect the drivers in the event the customer wants the grill and flange assembly
painted to match the wall color. Once the paint has dried remove the paint shield and re-insert the grill.
Note: A paper clip bent to have a small hook approximately 1/8” long makes a convenient tool for removing IW grills
without scratching the finish.
