Product Description

The Alesis M1 Active 520 is a newly designed, affordable, high-precision active reference monitor with Bass Density control and EQ. The M1 Active series offers incredible definition and flat frequency response from the high-precision drivers and a professionally crafted crossover. The cabinet and drivers have been redesigned for a bold new look and even greater sonic clarity.

The M1 Active 520 has a 1 inch thick front baffle, which minimizes speaker resonance, and the visually stunning acoustic waveguide evenly disperses high-frequency sound across your control room. The M1 Active includes new Bass Density technology, which allows you to tailor these monitors to any room’s acoustics. The distinctive top-mounted power/clip indicator lets you know if the speaker is clipping.

The M1 Active 520 features a 75-Watt amplifier and a 5 inch low frequency woofer, while the M1 Active 620 features a 100-Watt amplifier and 6.5 inch low frequency woofer.

Would you consider this product to be made well? How dependable?
The speakers are pretty heavy for there size they felt very solid as i was setting them up and getting them positioned. I imagine as with everything if i take good care of these they will sound like they do new for many years.

The filter switches on the back so that you can modify the sound to fit your needs wherever you place the speakers, with or without sub you can find a good sound.

Your general opinion of this product.
I am very impressed with these they have very low noise and give the music decent space, you can hear many panning positions within, not just R L or Center. The mid-range is detailed and crisp, Ive just tested them out with a variety of music Rock to dance and they sound quite accurate.
