Description
The Micro100x is a high-quality multi-purpose speaker suitable for use wherever top performance is required but
space is limited. A two-way design, it utilizes a 5 1/4-inch (135mm) bass unit with a cast-aluminum basket and Boston's
patented 1-inch black-anodized aluminum tweeter with AMDTM (Amplitude Modification Device). The AMD creates an
extremely smooth, accurate response, resulting in remarkably natural high frequency reproduction.
The Micro100x uses an extremely rigid and heavy die-cast aluminum enclosure to eliminate unwanted cabinet
resonances, for clearer sound. MagnaGuard®magnetic shielding allows placement next to a TV in a home theater
system without distorting the picture.
Five Micro100x speakers combined with a Boston powered subwoofer form the Micro Reference System10k, a home
theater speaker system that delivers no-compromise performance with virtually unlimited placement flexibility.
Grille Design
The grille is made of perforated metal with a high percentage of open area for minimum effect on high
frequency performance.
Enclosure Shape
The enclosure is carefully designed to optimize the system’s performance. The bass reflex port is precisely flared
at both ends to minimize audible port turbulence. The area surrounding the tweeter is smooth with minimal
recesses to maintain a smooth and transparent high frequency response.
The Micro100x is ideal for use as:
* The LCR and surround channels of a high-performance, space-conscious home theater system
* The stereo speakers of a compact music system
* A multiroom extension speaker
Heat Sink/Terminal Plate
Heat-producing crossover components are mounted to a die-cast aluminum heat sink for stable, consistent
performance at high power. This large heat sink also draws heat from inside the cabinet, keeping critical driver
components cooler. The tweeter has its own multifinned aluminum heat sink for increased power handling
and reliability.

How to Wire Your Speakers
You need to wire your speakers correctly to obtain the best sound quality and the proper image. Wiring should
just take a few minutes, but it’s important to do it carefully, since incorrect wiring (such as reversed connec-
tions) can result in a poor soundstage or poor bass.
We recommend using 18-gauge or larger speaker wire for runs up to 25 feet (8m), and thicker 16-gauge or larg-
er for longer runs. Strip 1/2-inch (12mm) of insulation off the ends of each speaker cable to expose the two con-
ductors and tightly twist the wire strands. Maintain consistency of the +(red) and –(black) connections by
using the markings on the wire.
IMPORTANT: Typically, one side of the wire is smooth.
Connect this side to the –(black) connection. The
other side has a rib or stripe. Connect this to the
+(red) connection.
Using the five-way binding posts:
The binding posts permit easy connection to banana
plugs, pins, spade lugs, and bare wire. The metal
surfaces are plated with 24K gold to prevent corrosion.
Insert the wire in the hole and tighten

Connections
WARNING: To prevent electrical shock, always switch off the amplifier or receiver when making connections to
the speaker.
Wire the Micro100x satellites as shown.
Consult your subwoofer's manual for the proper way to connect your subwoofer to your system.
Placement
For best results, place the speakers as shown.
A Note on Micro100x
Surround Channel Placement
For the most realistic surround effects, place the
surround speakers so the sound is diffused around
the listening area. Avoid pointing them directly at the
listeners.

Bookshelf Mounting
Self-adhesive cone-shaped aluminum feet are provided
to stabilize the speaker when used on speaker
stands or on the television. The speaker may also be
angled up or down by using the feet only at the front
or rear of the speaker.
Wall-Mounting the Micro100x
The Micro100x may be wall-mounted using the
supplied bracket. The speaker may be mounted
vertically or horizontally. The included toggle bolts
are designed for mounting on plasterboard.
Consult a knowledgeable installer for the proper
hardware to use on your wall.

Aftermarket Mounts
A single tapped hole on the back of the speaker can be used with any available pivoting bracket that uses
a 7/16”-20 thread. Consult your dealer for more details.
Setting Up Your Home Theater System
Volume Levels: To obtain the best home theater effect, match the sound levels of each speaker. Home theater
systems include a test signal that simplifies this level matching. Refer to the instructions provided with your
surround sound electronics.
Setting the Proper Speaker Mode
on Your Surround Sound Receiver:
For best results, choose the ”small“ speaker option for all channels and ”subwoofer-yes“ on your receiver's set-up
menu. This will divert all the low bass from the front, center, and surround channels to the subwoofer for the
greatest total system bass output. Use an RCA cable to connect the receiver's sub out jack to your subwoofer's
line in jack. Consult the instructions that came with your receiver and subwoofer for more detailed information
on speaker and subwoofer wiring.
Listening Levels and Power-Handling
The power recommendation for the system assumes that you will operate the amplifier in a way that will not
produce distortion. Even our rugged speakers can be damaged by a modest amplifier if it produces distortion. If
you hear a harsh, gritty noise, turn down the volume. Prolonged or repeated operation of your speaker with
a distorted signal from the amplifier can cause damage that is not covered by the warranty.
