Welcome to Anthony Gallo Acoustics
Thank you for purchasing the Anthony Gallo Acoustics Reference Strada 2 loudspeakers.
Years of engineering, development and testing ensure that these speakers will meet or
exceed your expectations and provide you with outstanding performance and value.
The Strada 2’s are provided in a center configuration for mounting in a horizontal orientation
and in a side configuration for mounting in a vertical orientation, for use as the left and
right loudspeakers for stereo or home theater listening.
Please take a few minutes to read this Owner’s Manual to acquaint yourself with these
special features and help you set up and use you Strada 2's. If you have any questions
regarding your Strada 2's, please contact us by phone at (855) 424-2556 US,
About Your Strada 2’s
Because of our patented S2 technology, Strada 2's perform as though it’s speaker enclosure is
significantly larger than it actually is, yielding a rich, full bodied and dynamic sound quality
than would otherwise be possible in speakers of this size.
Strada 2’s perform equally well when wall-mounted and provide amazing performance,
regardless of the size of your listening area.
The Strada 2 is the first speaker in the Anthony Gallo Acoustics line to utilize the company’s
proprietary Optimized Pulse Technology (OPT & OPT level 2). OPT is an impulse correction and
synchronization system designed to integrate the low, middle, and high frequencies into one
unified sound source. (Please visit our technology section at www.roundsound.com for more
info.)

Introduction
Strada 2’s also incorporate our patented CDT™3 cylindrical diaphragm transducer,
redesigned to employ our latest speaker technology.
The unique design of the CDT3 tweeter and its cylindrical shape provide a dispersion
pattern of 120 degrees for the center configuration and 180 degrees for the side
configuration (Figure 1). This allows substantial flexibility in positioning the speakers, since
the same high-frequency response is delivered off-axis as is on-axis.
The CDT3 and the patented S2 technology form a winning combination of clarity, precision
and range not found anywhere near this price point for a speaker system. The S2 technology
decouples the backwave of the driver from the air inside the enclosure. The benefits of our
S2 technology in your home stereo speakers include superior low frequency extension,
improved transient response and a substantial increase in efficiency.
In concert with the OPT system, the re-engineered CDT tweeter and the patented S2
technology are crucial elements that combine to provide a truly emotional audio experience.

Placing Your Strada 2's
If achieving maximum bass and warmth is your goal, the Strada 2’s should be placed near a
wall or other large surface.
The speakers can be mounted at any reasonable height. Point the Strada 2’s toward the
listening area to reduce floor and ceiling reflections. (Example: If seated at a desk, have the
Stradas on table stands and adjust the angle of the speakers until they are pointing directly
towards to your ears.) The left and right front speakers should be positioned so they are at
the opposite ends of the base of a triangle whose tip is at the listening area (Figure 2).
Note: Strada 2's can be mounted on floor stands, table stands or wall mounts. They are
also very effective near field speakers and sound superb on a desktop or in home office.
They can even be placed in a cubbyhole or wall unit without significant degradation in
sound quality. (When placed in a cubby or wall unit it is important to position the speaker
as close as possible to the opening of the enclosure. This will minimize reflections and
increase accuracy) Refer to page 8 for additional information concerning these mounting
alternatives.
An example of a stereo (2.0 configuration) setup using two floor-mounted Strada 2’s is
shown in Figure 2.

An example of a stereo with subwoofer (2.1 configuration) setup using two floor-mounted
Strada 2’s and a Gallo TR-3D subwoofer is shown in Figure 3
Note: The subwoofer can be positioned practically anywhere, since low frequency
audio below 80 Hz is non-directional. However, best results are usually obtained
when the subwoofer is placed between the left and right front speakers.

floor-mounted Strada 2’s, one table-mounted Strada 2 front center loudspeaker, two floor-
mounted Stradas, and a Gallo TR-3D subwoofer is shown in Figure 4.
Note: In a typical home theater with five Strada 2’s, a 7.1 configuration is not required.
