Visual communication is a powerful thing, but nothing adds to the overall impact like
high-fidelity audio. Flat panel displays (FPDs) are the video communication media of choice
for corporate, institutional, retail, and commercial clients – anyone who wants to present
high-impact, high-resolution visual information.
Unfortunately, choices for FPD audio playback have been limited to low-performance,
poor-quality speaker systems. Until now.
Introducing the Altec Lansing SLS6221 system. The first professional-quality 2.1 powered
audio system specifically designed for use with FPDs. Now you can provide your clients
with high-fidelity, high-definition audio to match the quality of their video presentations.

A ported subwoofer completes the sound with low-frequency, full-throated bass. Set in a low-resonance
wood cabinet for maximum sound with minimal distortion, the narrow-profile cabinet contains a long-
throw 6.5” (165 mm) woofer designed to reproduce dynamic audio program material down to 32 Hz.
The subwoofer also contains seven discrete power amplifiers and the line array circuitry.
Note the controlled, uniform vertical dispersion
pattern of the high-frequency program material.
The audio is directed at the listener, not at floor
or ceilings. The music and voice reproduction
comes right at you, in its purest, most natural
form uncluttered by reflections.
 Orange = Discernable sound
The Altec Lansing SLS6221 features two ultra-slim satellites with a total of
twelve 1” neodymium micro drivers, with each pair of micro drivers
powered by its own discrete amplifier. From 150 Hz to 20 kHz, the
frequency spectrum is split into three distinct overlapping bands and fed into
micro drivers that are set at a precise distance from each other. A
combination of precise driver spacing and low pass filters for each pair of
drivers delivers a predictable vertical coverage pattern of 40˚ – 60˚ above
1,500 Hz. The end result is a crisp, high-fidelity, fully intelligible sound that is
focused on the listening area.
Whether placed at the head of a corporate board room or as part of a high traffic point-of-sale
retail kiosk surrounded by reflective surfaces and high ambient noise, the sound must be
delivered to its audience with minimal impact to surrounding locations. The Altec Lansing
SLS6221 uses patent pending line array technology to focus voice and music into the area
directly in front of the plasma screen.
Advanced Technology
Delivers Predictable Sound Coverage
SLS6221
The World’s Smallest Line Array
• SLS6221 satellites are magnetically shielded to work with any
 kind of display, including standard CRTs. The subwoofer is
 not magnetically shielded.
• A wired control pod and wireless IR remote allow you
 to adjust volume, bass and treble, as well as mute
 the entire system.
• A headphone jack located on the control pod allows
 private monitoring of the audio output. Use of the
 headphone jack mutes the speakers.
• The SLS6221 is offered in 120 V, 220 V and 230 V versions.
Powerful Subwoofer
Versatility of Installation
Additional Features
Each SLS6221 system comes with three convenient
mounting options:
• Bracket system to mount the speakers to the
 center mounting position of most FPDs.
• Satellite stands for use on table tops.
• Threaded inserts on the back of each satellite for
 surface or ceiling mounting using standard
 industry mounting brackets.
Low pass filtering actively directs
specified frequencies of sound to
a different pair of micro drivers.
This process, combined with the
critical distance between each
micro driver, creates the focused
coverage pattern in front of the
flat panel display.
SLS6221
Hard-wired cables (3 m / 9.8 ft.) with an additional extension cable (2 m / 6.6 ft.)
are provided for satellite to subwoofer connections. A stereo RCA input cable (5
m / 16.3 ft.) is also provided for connecting the FPD to the subwoofer.
