High Performance Compact
Home Theater Loudspeaker System
Thank you for choosing Atlantic Technology home theater products. Your new speaker system is
precision crafted to give you years of enjoyable, trouble free service. This manual covers the Atlantic
Technology System 170 series of speakers for home theater. It will show you how to incorporate
System 170 components into your present setup, as well as how to assemble a complete system. The
Model 172 PBM Subwoofer is covered in detail in a separate manual. System 170 has been optimized
for use with any surround sound format including Dolby Surround
®
, Dolby Pro-Logic
®
, Dolby Digital
5.1
®
and DTS
®
digital surround formats.
Model 171 LR Front Channel Speaker
The
Model 171 LR Front Channel Speakers
are two-way systems
intended for use only with
a quality subwoofer
, such as the Atlantic Technology Model 172 PBM. Each speaker contains two
4" CCMG (coated composite molded graphite) woofers, and a 1" Ferrofluid
®
cooled silk dome tweeter
using a powerful neodymium magnet, in an acoustically inert MDF cabinet. The 171 LR speakers are
magnetically shielded so they may be placed right next to a TV set without concern.
Model 173 C Center Channel Speaker
It is vital to the accurate reproduction of a multi-channel soundtrack that the three front speakers have
the same sonic signature. Therefore, the
Model 173 C Center Channel Speaker
contains the same
two 4" CCMG woofers and 1" Ferrofluid
®
cooled silk dome tweeter as the 171 LR speakers. The 173 C is
designed for use in multi-channel home theater systems
only as a dedicated center channel
speaker
. It includes a high frequency level control that allows it to be placed directly above or below
the TV screen (which changes the sound) and still provide accurate reproduction. Since up to 85% of
dialogue and 65% of special effects are reproduced through the center channel speaker, it’s important
that its sound be accurate and timbre-matched to the other speakers in the system. The rear-mounted
High Freq control incorporated into the 173 C allows for this matching.
The 173 C center speaker is intended to be placed in a horizontal position, as opposed to the vertical
positioning intended for the 171 LR. It too is magnetically shielded so it may be placed directly
adjacent to your TV set with no adverse effects.
Model 174 SR Surround Speaker
The
Model 174 SR Dipole Surround Speaker
is intended for use in multi-channel audio/video
sound systems
only as a dedicated surround channel speaker
. Each speaker has two of the same
4" CCMG woofers as the front speakers and two broad dispersion 3/4" Modified Dome tweeters. The
drivers are angled and electronically phased to produce ambience without localization. The 174 SR’s
wide bandwidth and unique construction makes it especially suitable for advanced Dolby Digital and
DTS applications.
Important Note: There is a dedicated LEFT and RIGHT model 174 SR. This is clearly marked on the back of
each speaker. Should you hang them on the wall using the supplied keyhole adapters, you must turn the
speakers over (hanging them “upside down”) and swap them side to side for proper operation.
