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 connections) 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 larger for longer runs. Strip

" (12mm) of insu-
lation off the ends of each speaker cable to expose the two conductors and
tightly twist the wire strands. Maintain consistency of the

nections by using the markings on the wire.
IMPORTANT:
Typically, one side of the wire is smooth. Connect this side to the

connection. The other side has a rib or stripe. Connect this to the

Description
The Boston Acoustics Micro System9000 II and Micro System9500 home theater speaker systems deliver
powerful performances for movies and music from small speakers that virtually disappear in your listen-
ing room. The potent 120-watt PowerVent
®
subwoofer in the Micro System9000 II and the earth-shaking
300-watt PowerVent
®
subwoofer in the Micro System9500 both produce exciting bass and powerful low-
frequency effects. In the Micro System9500, the four Micro90x II satellites and Micro90c II center channel
all use the same drivers, creating a perfect sonic match across the front and rear stage. Each speaker
houses a Boston-built, high-power, 3

⁄
2
" (89mm) midrange driver and our 1" (25mm) anodized aluminum
dome tweeter with AMD to provide articulate dialog and lifelike imaging. These same drivers are also
used in the front left/right satellites and center channel in the Micro System9000 II. All of the satellites in
both systems include wall-mount brackets for complete placement flexibility.
The key to both system’s powerful performance are the subwoofers’ high-current amplifiers and DCD
™
(Deep Channel Design) bass unit in a ported, down-firing enclosure. Built in Boston’s state-of-the-art
production facility, this long-throw driver was optimized using Finite Element Analysis computer
modeling, giving it tremendous excursion for exceptionally powerful bass. The subwoofer amplifier
features active equalization, extending the system’s bass response down to 26Hz in the Micro
System9500 and 29 Hz in the Micro System9000 II. The down-firing ports further strengthen the deep
bass response by coupling the subwoofer’s output to the floor, and are smoothly flared to eliminate
audible turbulence. In addition, they both feature BassTrac
®
, a proprietary new Boston-designed circuit
that tracks the input signal to the subwoofer and prevents its amplifier from being driven into audible
distortion. The benefit: The bass stays clean and strong at any listening level. For user convenience, the
subwoofer features auto turn on/turn off circuitry that turns the subwoofer amplifier on automatically
when a signal is sensed, and turns it off approximately 15 minutes after the last signal has been received.
Easily accessible volume controls make both PowerVent subwoofers as convenient to use as they are
exciting to listen to.
The Micro90x II and Micro80x II satellites and Micro90c II center channel are two-way speakers designed
for wide-range response and a seamless blend with their respective subwoofer. They all feature
MagnaGuard
®
magnetic shielding to prevent television picture distortion.
