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.

Limited Warranty

For five years from the date of purchase, Boston Acoustics will repair for the original owner any defect in materials

or workmanship that occurs in normal use of the Micro100x speaker, without charge for parts and labor.

Your responsibilities are to use the system according to the instructions supplied, to provide safe and secure

transportation to an authorized Boston Acoustics service representative and to present proof of purchase in the

form of your sales slip when requesting service.

Excluded from this warranty is damage that results from abuse, misuse, accidents, shipping or repairs or modifications

by anyone other than an authorized Boston Acoustics service representative.

This warranty is void if the serial number has been removed or defaced.

This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

If Service Seems Necessary

First, contact the retailer from whom you purchased the speaker(s). If that is not possible, write to:

Boston Acoustics, Inc. 300 Jubilee Drive Peabody, MA 01960 U.S.A.

We will promptly advise you of what action to take. If it is necessary to return your speaker to the factory,

please ship it prepaid. After it has been repaired, we will return it freight prepaid in the U.S. and Canada.
