Innovative sound quality with damperless design
Single suspension design creates amazing reality
Unique structure to ensure stability without damper
In a typical speaker unit, a damper (rear suspension) is used to maintain the stability of the vibration system. However, Markaudio adopts a structure that moves the center of gravity of the drive unit forward and supports it only with the front suspension. This ensures linearity and stability of operation even without dampers, and increases the degree of freedom of sound.
Excellent diffusivity due to shallow cone shape
The cone is shallow and has a gently curved front Negative Chamber Corn Profile. The design is more difficult, but it keeps the directivity very low, allowing you to enjoy a natural and expansive sound wherever you are in the room.
High purity of sound obtained by the absence of a damper
The absence of a damper ensures that the signal sent by the amplifier travels directly from the voice coil to the cone, accurately reproducing even the smallest nuances of sound. The effect is especially noticeable in delicate expressions such as whole tones, reverberation, and applause.
Soft and supple vibration system movement
It is supported only by a front suspension made of synthetic rubber. Since there is no physical braking by the damper, the vibration system moves freely and naturally reproduces the dynamics and atmosphere of the music. This highly compliant structure gives the music a sense of reality and rich dynamics.

Benefits of a single suspension structure
"We achieved overwhelming transients and clarity."
The Alpair7MS's core single-suspension structure (mono-suspension) dramatically improves sound rise and convergence (transients) over traditional double-suspension units. This made the sound contours very clear and the clarity was noticeable.
"The amount of information has increased dramatically."
The simplified suspension structure reduces unnecessary braking and ensures that the cone movement is extremely faithful to minute signals. As a result, you can feel that the amount of information such as the depth of the sound field and the sense of atmosphere has increased significantly.
Sound characteristics and musicality
"It achieves both deep sound field expression and high resolution."
While maintaining the high resolution of the conventional Alpair series, the mono-suspension adds depth to the sound field expression. Especially in the reproduction of acoustic instruments and vocals, I feel the raw reality.
"It's light, but it has a tighter low frequency than expected."
The unit has a light vibration system, but when combined with a well-designed enclosure, it reproduces more volume than expected and tight low frequencies.
