About the M1 Active Mk2

TONE

Tonally, every effort has been made to create a powered monitor that is as linear as possible, representing a flat frequency response from 50Hz to 20KHz

±2dB. (see p. 21) Additionally, the use of electronic crossovers within the critical upper midrange frequencies has reduced phase and time delay anomalies often associated with passive crossovers. By including discrete woofer and tweeter amplifiers and application-specific electronic high and low pass crossover filters in the same enclosure the tonal accuracy of the M1 Active Mk2 will always remain constant.

ABOUT THE DRIVERS

The M1 Active Mk2’s 6.5” woofer cone is made of proprietary non-woven carbon fiber. This material is 25% lighter than polypropylene with twice the stiffness for quicker transient response in the low-to-midbass region and vastly improved midrange intelligibility (over polypropylene at 2000 Hz). The non-woven carbon fiber cone, along with the closed cell synthetic rubber surround, are both nearly impervious to ozone, direct sunlight, heat and humidity. Therefore, after an initial break-in period, the sound should remain virtually unchanged for the life of the product.

Alesis’ proprietary-design tweeter features a special wave guide baffle to improve polar response, a silk dome, and low viscosity ferrofluid formulated specifically to retain the best balance of transient response to power handling. The shielded tweeter utilizes a vented pole piece with a separate rear chamber to lower the free air resonance. The low 2000Hz crossover point of this tweeter produces a very widely dispersed, low-distortion signal within the critical midrange frequencies. It is these frequencies which are often the most problematic to get “right” during a mix. The tweeter is designed for an optimal response for non-fatiguing, long term, high level, nearfield mixdowns. This design results in a flat, linear mix when played back on home or car systems from appropriate distances.

MAGNETIC SHIELDING

Your M1 Active Mk2s are at home in recording environments wherein video is a major component. They are magnetically shielded for use in fairly close proximity (3” minimum) to a computer monitor or video screen. (Non- shielded components can make the colors of a screen “smear” or appear out of focus if the speaker is too close.) Magnetic shielding was designed into both the woofer and the tweeter from the beginning so that the system exhibits about low magnetic leakage. Shielding of both the woofer and the tweeter is accomplished by the use of a second opposing-field-oriented “bucking” magnet.

M1 Active Mk2 specifications

The Alesis M1 Active Mk2 is a well-regarded studio monitor designed for musicians, producers, and audio engineers seeking high-quality sound reproduction at an accessible price point. With a focus on delivering accurate sound and a balanced performance, the M1 Active Mk2 has become a popular choice for both home studios and professional environments.

One of the standout features of the M1 Active Mk2 is its bi-amplified design. Each speaker is powered by dedicated amplifiers that optimize the performance of the woofer and tweeter separately. This bi-amplification ensures clear and precise sound reproduction across the frequency spectrum. The 6.5-inch low-frequency driver is designed to deliver robust bass response while the 1-inch silk dome tweeter provides smooth high-frequency performance, resulting in a well-rounded audio experience.

The M1 Active Mk2 incorporates advanced technologies to enhance its performance. The monitor features a front-firing bass port that helps to minimize boundary coupling and improves the overall bass response, allowing for placement flexibility within the studio. This design reduces the risk of unwanted resonances caused by proximity to walls, ensuring accurate sound even in challenging acoustic environments.

Another important characteristic of the M1 Active Mk2 is its frequency response, which ranges from 55 Hz to 20 kHz. This wide frequency range makes it suitable for various musical genres and audio applications, enabling users to hear detailed nuances in their mixes. Additionally, the monitor is equipped with a rear-mounted EQ control, allowing users to tailor the sound to their specific acoustic space, mitigating the effects of room acoustics on playback.

Durability and design are also key aspects of the M1 Active Mk2. Its rugged enclosure is built to withstand the rigors of studio use while also providing a sleek and professional appearance. The monitors can be easily positioned on desktop surfaces or mounted on stands, making them versatile for different studio setups.

Overall, the Alesis M1 Active Mk2 stands out as a reliable and affordable option for anyone looking to improve their audio monitoring capabilities. With its bi-amplified design, advanced technologies, and customizable features, this studio monitor delivers impressive sound quality suitable for both amateur and professional recording applications. Whether mixing, mastering, or simply enjoying music, the M1 Active Mk2 is designed to deliver a true-to-source listening experience.
