System 250.1

High Performance 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 250.1

 series of speakers for home

theater. It will show you how to incorporate the following System 250.1 components
into your present setup, as well as how to assemble a complete system. The 

Model 262

PBM Subwoofer

 is covered in a separate manual. The entire 250.1 system has been

optimized for use with Dolby Digital AC-3.

The 

Model 251.1 LR Front Channel Speakers

 are two-way systems for use with a

quality subwoofer, such as the Atlantic Technology Model 262 PBM. Each speaker
contains two 4" polypropylene, long-throw woofers, and a 3/4" ferrofluid cooled tweeter
in an acoustically inert MDF cabinet.

The 

Model 253.1 C Timbre Adjusting Center Channel Speaker

 contains the

same two 4" polypropylene long-throw woofers and a 3/4" ferrofluid cooled tweeter. It is
designed for use in home theater systems that use a dedicated center channel speaker.

The 

Model 254.1 SR On-Wall/In-Wall Surround Speaker

 is intended for use in

audio/video sound systems with dedicated surround channel speakers. Each speaker has
two 4" polypropylene woofers, as well as two 1/2" polypropylene tweeters which are
angled and phased to produce ambience without localization for movie surround
soundtracks. Its wide bandwidth and unique construction makes it especially suitable
for Dolby Digital AC-3 applications.

Although the speakers in the Atlantic Technology System 250.1 are acoustically and
cosmetically matched to each other, they may also be used with a wide variety of other
speaker systems from other manufacturers with satisfying results.

Note:

 The 254.1 SR is not intended for use as a regular right and left front channel stereo

speaker or satellite. Its spatial performance characteristics are not designed for this purpose.
In the Atlantic Technology 250.1 Series of components, the Model 251.1 LR fills this role.

Connection

We recommend that you connect your new System 250.1 speaker components using
high quality stranded wire of 18 gauge or larger for lengths up to 25 feet. Use 16 gauge
or larger for longer runs of wire. Contact your local audio/video specialist for more
specific information.

Warning: 

To prevent risk of electrical shock or damage to your equipment, always switch off

the amplifier or receiver when making connections to the speaker.
