Based on ported acoustical instrument principles

 (violins, 

cellos, guitars), the uniquely shaped tubular Acouti-Port on the 
redesigned AT-Series speakers were researched and molded with 
the same dedication a fine crafstman spends carving an instru-
ment. By studying the different sound properties of composite 
materials, the size and shape of the speaker's ports and the way 
tones would escape form the speaker's body, new life is brought 
to music. Finally, a mid-level in-wall speaker has been intro-
duced that will have audiophiles taking note!

Smooth, Rich Bass Response for Large and Small Outdoor 
Areas.

 Available in either the 5" OA-502 or the 6" OA-602, 

Audioplex's new ultra-rigid poly-mica woofers offer bass 
response never heard before. Specifically designed to 
reproduce the exact tones and timbres lost in the outdoors, the 
OA-502 and 602 both deliver extraordinarily satisfying deep 
bass with chest thumping impact! Choose the OA-502 when 
your speakers can be placed within 12' of your listening 
position and the OA-602 when you have a larger area to cover.

Smooth, Natural Response with Unprecedented Clarity and 

TM 

Detail

 because of Audioplex's WeatherDome tweeter. The 

WeatherDome utilizes advanced composite materials in a 
uniquely shaped mount. A product of years of research and 
development, the Audioplex WeatherDome is the first tweeter 
ever produced for an outdoor speaker that exhibits truly broad 
bandwidth and ultra-smooth response. 

High Technology Enclosure and Brackets

 are completely 

weatherproof. A revolutionary new technique enables Audioplex 
to completely cover all parts of the enclosure with a penetrating 
and even coating of protective material. Guaranteed not to fade, 
chip or peel for five years, the grill and enclosure finish protects 
the OA-Series from the harshest elements.

New Version! 

Our popular OA-602 is now available in a 4 ohm 

version providing a 3dB boost over the original! Now you can 
put the power of your system to where it's needed the 
most...outdoors.

Convenient Mounting Accessories

 include Audioplex's 

swiveling weatherproof bracket and all necessary mounting 
hardware. Unlike competitors that charge extra for mounting, 
Audioplex includes everything but the speaker wire for your 
installation. OA Series speakers are covered by a 5 year warranty.

Finely tune the AT-Series

 for rooms with many reflective, 

hard surfaces or for rooms with dull, sound absorbing 
attributes. The in-wall AT-Series features a swiveling tweeter 
with +/-3dB of adjustment quickly allowing custom installers 
to compensate for different room characteristics.
