Innovative sound quality with damperless design
Amazing reality created by single suspension design
Unique structure that ensures stability without using dampers
A typical speaker unit uses a damper (rear suspension) to maintain the stability of the vibration system. However, Markaudio uses 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 a damper, and increases the degree of sonic freedom.
Excellent diffusivity due to shallow cone shape
The cone is shallow and uses a Negative Chamber Corn Profile with a gentle curve on the front. Although it is more difficult to design, the directivity is kept very low, allowing you to enjoy natural and spacious sound no matter where you are in the room.
Highly pure sound obtained by not having a damper
Because there is no damper, the signal sent from the amplifier is transmitted 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, reverberations, and applause.
Soft and supple vibration-based movement
It is supported only by the synthetic rubber front suspension. Since there is no physical brake applied by the damper, the vibration system moves freely, naturally reproducing the strength and atmosphere of the music. This highly compliant structure gives music realism and rich dynamics.

The Benefit of a Single Suspension Structure
"Achieves overwhelming transient response and clarity."
The core single suspension structure (mono suspension) of the Alpair7MS dramatically improves the attack and decay (transients) compared to traditional double suspension units. This results in extremely clear sound contours and outstanding clarity.
"Faithfully reproduces fine details. The amount of information is significantly increased."
Simplifying the suspension structure reduces unnecessary damping, allowing the cone to respond very precisely to subtle signals. This makes it possible to perceive a remarkable increase in information, such as the depth of the soundstage and the sense of air.
Sound Characteristics and Musicality
"Balances deep soundstage expression with high resolution."
While maintaining the high resolution of the conventional Alpair series, the mono suspension adds depth to soundstage expression. Especially in the reproduction of acoustic instruments and vocals, the realism is strikingly vivid.
"Lightweight yet unexpectedly tight bass."
Although the unit has a lightweight diaphragm system, when combined with a well-designed enclosure, it reproduces a surprisingly full and tight, controlled bass.
