The satellite speakers come with removable stands. If space is tight, simply detach the satellites from their bases and mount them on the wall.

Altec Lansing FX4021

Caleb from Ames, IA on 5/1/2008

Having previously been using a 2.0 stereo system, this purchase was clearly an improvement. While not an extremely loud system, it is perfect for a dorm room, den, or office. The highs are very clear and crisp (probably the systems strong point) and the bass is sufficient. I listen to it at nearly flat equalization with the loudness turned on and am very pleased with this purchase. It is used with my laptop and iPod, most music at 192 kbps mp3 format. Not having a very good ear for musical frequencies, it seems that the mids could be a bit lacking, but I could be wrong. However, clarity is excellent. I have owned it for eight months and have experienced no problems. If one thing could be improved, I would wish for more volume, but I'm sure that can be bought with a higher price tag.



Great at work

Matthew from Charlotte, NC on 3/12/2008

I compared these to the Klipsch 2.1's, which I owned and loved. I needed something for my cube at work where I can't turn them up but they have to be able to cut through a lot of ambient noise and still be balanced. Where, at low volumes, the Klispch 2.1's sounded muffled and lost bass in the ambient noise, the Altec's sounded great and came with more features like the remote. The Klipsch kick Altec out of the water when cranked up, but for a desktop application, they were the big winner. I position the sub directly below the monitor on the floor and each speaker beside the monitor about 2 feet from my head.




Hands-on research

Product Research



Overview: The Altec Lansing FX4021 is a 2.1-channel powered speaker system for use with a DVD player, CD player, computer, or game system.

Satellites: Each satellite speaker has a removable base. The bases can be replaced by optional wall mount brackets available from the Altec Lansing. The satellites are magnetically shielded.

Subwoofer: The powered subwoofer features two 5-1/4" long-throw drivers in an isobaric enclosure. The entire perimeter around the top of the subwoofer is vented for bass output. The amplifiers for the system are located in the subwoofer. The subwoofer is not magnetically shielded so it should be placed at least two feet from a CRT monitor of computer CPU.

SFX Technology: Sound Field Xpander Technology delivers a wider stereo image for bigger sound.

Control Pod: A wired pod keeps controls within easy reach. A rotary wheel adjusts volume, bass, and treble. On/off buttons control power, loudness, and SFX. On the side of the pod are two 3.5mm mini-jacks; one headphone output and one auxiliary input.

Note: If signals are fed to both the main and auxiliary inputs simultaneously, they're both played through the speakers (not generally a good thing).

Wireless Remote Control: The system features a wireless remote that adjusts volume, bass, treble, loudness, SFX, and stand-by (on/off). The remote also has a reset button which returns the tone controls to the factory setting.

Subwoofer Connections: On the back of the subwoofer are RCA outputs for both satellites, a 3.5mm stereo mini-jack input, and a DIN plug for the wired control pod.


Power Output: 46 watts RMS total output power:

  • Subwoofer: 24 watts RMS @ 10% THD
  • Satellites: 11 watts RMS each @ 10% THD

Frequency Response:

  • System: 32 Hz to 20 kHz
  • Subwoofer: 32 Hz to 180 Hz
  • Satellites: 180 Hz to 20 kHz
