Shake the walls of the largest rooms with amplified premium sound! The M1 Active 520 offers incredible bass and midrange definition, and flat frequency response from its high-precision driver and professionally crafted crossover. It also allows you to customize to your listening preferences via the bass density control and EQ switches.

Besides superior audio performance, its new bold look makes it the highlight of you room. The magnetically shielded design ensures safe use near video monitors in computer-based music production studios.

  • newegg Excellent sound The lightweight, compact cabinet houses a 5" low frequency woofer for clear bass and midrange, and a 3/4" silk dome tweeter for smooth, detailed highs without harshness. The two high-precision drivers deliver lower distortion and smoother frequency response. Acoustical waveguide offers superior imaging with minimal diffraction. The bi-amplified design with 25W power for the tweeter and 50W power for the woofer ensures ultra accurate frequency separation. Plus, the 1"-thick front baffle virtually eliminates speaker resonance. The rear port design provides deep bass extension and increased SPL. The speaker is also magnetically shielded for noise-free audio when placed near a video monitor. Immerse yourself into your favorite sound!
  • newegg Versatile switches This speaker comes equipped with hi, mid, and low frequency EQ switches to accommodate user preference. Also, the low frequency density switch is offered for acoustic space adjustment of the monitors.
  • newegg Audio Interface The XLR and 1/4" TRS input connectors allow you to connect it to a variety of audio devices. Audio can be played through the speakers, or directed to the computer and recorded.

4 out of 5 eggsTrue Sound

Pros: They are exactly what they say they are.

Cons: None, but I knew what I was getting. See other thoughts.

Other Thoughts: I've tried many different speakers for my computer and I have been disappointed with all of them. I decided to use a better speaker.

Unlike most powered reference speakers, these are shipped by the pair.

Huge improvement over my AudioEngine 2 speakers (my previous "best" 2.0 set) which sound muddy in comparison. Of course the AudioEngine 2 is much smaller and artificially boosted the low end to sound bigger.

These speakers do not color the sound as much as computer speakers do. These are designed to present accurate sound. This can be an eye-opening experience to those that might try these as computer speakers. They easily make the quality loss of MP3 compression audible. Feed them a quality signal and they rock!

When I hooked these up for the first time I found out that there was EMI interference affecting my on-board audio whenever I moved the mouse, scrolled, accessed the hard drive, etc.., the resolution for me was to disable the Intel C1E Support in the BIOS.
