Anthony Gallo TR-3 Subwoofer - Manual (Page 3)

Patented S2 Technology
The patented S2 technology is a very simple, yet very powerful approach to solving various
acoustic problems inherent to the internal acoustics of any loudspeaker. With respect to the
acoustic sphere, S2 is a material that will act to neutralize the effect of the Hemholtz resonance
while simultaneously damping internal reflections ("chatter").
A further benefit of S2 is in low frequency extension. Because S2 seems to mechanically couple
with the driver at low frequencies, but decouple at mid and high frequencies, it allows the driver to
behave as if it were in a larger enclosure to produce lower frequencies than it ordinarily would. In
fact - this is precisely the innovation that made the original Micro possible and where Gallo
speakers truly depart from "me too" spherical speakers.
Every spherical loudspeaker enclosure has these naturally occurring problems of Hemholtz
resonance and internal "chatter." This becomes especially problematic when employing full-range
drivers such as those found in the Micro and the A'Diva. Thanks to S2, these Gallo products can
truly differentiate themselves from lookalike imitation products - they all fall victim to the problems
that S2 solves, which is why you can always count on Gallo products for real high-performance
when the competition falls short.
Combined with our S2-enhanced compact subwoofers, the Micro and the A'Diva create stunning
soundscapes of beautiful music and cinematic excitement. S2 has made the Compact Home
Theater/Stereo a no-compromise High Definition Audio Experience.

Introduction
Welcome to Anthony Gallo Acoustics!
Thank you for purchasing our Anthony Gallo Acoustics TR-3 active subwoofer. To help you get the most
out of your new acquisition, please take 10 minutes and read over this owner’s manual. It’ll familiarize
you with the TR-3’s basic features while teaching you certain setup tips on how to optimize its
installation with the remainder of your present loudspeaker system. Let’s begin with a well-known
subject that still bears repeating:
Break-In: Like any high-quality loudspeaker system that uses superior drivers, the TR-3 undergoes
break-in during which the suspension of its internal spider and the external rubber surround reach their
proper compliance. Break-in is simply a function of x-number of excursions until the springy materials of
the woofer soften to their optimum state. Loud low bass accelerates break-in, lower playback levels
prolong it. After 50 hours of optimal break-in, the TR-3 will have stabilized and perform as intended. Do
not judge its performance prematurely and reserve final adjustments to its gain control after the break-in
period is over.
Basics: The term ‘subwoofer’ is quite descriptive. Sub…marine: below the waters surface;
sub…woofer: below the woofers of your main speakers. Depending on your main speaker’s bass
response, a true subwoofer will be used in one of two ways: Filter or bypass mode. More on that later.
Let’s start with an introduction to our Patented S2 Technology.
