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

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.

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.

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.

The Altec Lansing PT6021 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 

PT6021 uses patent pending line array technology to focus voice and music into the area 

directly in front of the plasma screen. 

Delivers

Each PT6021 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.

• PT6021 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 universal remote lets you control the speakers, TV, 

and other electronics.

• A headphone jack located on the control pod allows private 

monitoring of the audio output. Use of the headphone jack mutes 
the speakers.

• The PT6021 is offered in 120 V, 220 V and 230 V versions.
