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.
