Proprietary AGA Technology
The following unique technology used in these AGA products was specifically developed by Anthony
Gallo and cannot be found in any other subwoofers. This technology contributes to an enhanced level
of bass output, precision bass reproduction, and dynamic range not found in other subwoofers
anywhere near the TR-1D / 3D’s price.
S2 Damping System in a Sealed Enclosure
AGA’s patented S2 technology is a simple, yet powerful,
approach to solving various problems inherent in the internal acoustics of any
loudspeaker. S2 is a material that acts to neutralize the effects of internal resonances within the
enclosure while simultaneously damping internal reflections (chatter). A further benefit of S2 is the
enhancement of the woofer’s low-frequency extension. Unlike typical enclosure damping materials
(fiberglass, Dacron, etc.), S2 mechanically “couples” with the rear pressure waves within the enclosure
at low frequencies. The result is that it not only “tricks” the driver into behaving as if it were in a larger
enclosure, it actually lowers the resonant frequency of the driver/enclosure combination. This enables it
to produce deeper and more powerful bass than it ordinarily would. In fact, this is precisely the
innovation that made the original Gallo Micro and other compact Gallo speakers deliver surprisingly
full-range sound from compact enclosures.
