AVOIDING DAMAGE

The best protection against speaker failure is to mix at a reasonable listening level. With a +4 dBu input and the input level control set to “6”, the M1 Active Mk2 speakers produce a sound pressure level (SPL) of 85 decibels at 1 meter, which is a good working level for mixing. At maximum output before clipping, they can generate peak levels ≥ 118 dB SPL at one meter – a level which may cause hearing loss after prolonged exposure. While the biamplified design of the M1 Active Mk2 avoids the common “blown tweeter” problem of conventional designs (when a broadband amplifier clips on a bass note, it sends unusually high energy to the tweeter, which tries to reproduce the square wave), it is not invulnerable. If you need higher power levels, you are not using the speaker in a near-field application. For extremely loud mid-field and far-field monitoring, we recommend the Alesis Monitor Two speaker with a 300-watt per channel amplifier. Many studios will check recordings on both systems, alternating to avoid ear fatigue and to gain perspective on the mix.

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.
