Descrizione del prodotto Markaudio Alpair-7MS Grey Woofer a Gamma Completa

The advanced design Alpair 7MS (mono suspension) is a radical departure from previous models. The 7MS is completely new, utilizing many new design components and manufacturing processes. The two main features are the patent-pending Negative Camber Cone and the Mono suspension system. Other key features include a custom-designed, gas-flowed glass-fiber chassis and dedicated ultralight voice coil.

Highlights

  • Latest model.
  • The run-in time for the 7MS is significantly reduced compared to previous models. Ten hours of light music at moderate volumes are sufficient for the suspension to reach its optimal operating pattern.
  • An Arrestor (as deployed in previous Alpair models) provides an audible warning of the accidental excess excursion.
  • The low-mass coil has a vented former and the motor employs a custom made copper plating to reduce distortion.
  • The MS7 is a bass capable audio driver with comparable performance to light-medium load traditional mid-bass units of the same size.

Product details

Markaudio Alpair-7MS Grey 4" Full Range Woofer

After releasing the Pluvia range of drivers, which have been well-received, Mark set about the next design evolution. As some of you will know Marks design ethos is mechanical efficiency, adding lightness and simplifying where possible. In these new drivers, Mark has managed to achieve much more with much less.

The advanced design Alpair 7MS (mono suspension) is a radical departure from previous models. The 7MS is completely new, utilizing many new design components and manufacturing processes. The two main features are the patent-pending Negative Camber Cone and the Mono suspension system. Other key features include a custom-designed, gas-flowed glass-fiber chassis and dedicated ultralight voice coil.

The 7MS cone is an ultra-shallow design affording a wide dispersion pattern. The outer section of the cone profile is angled backward creating a +180 degrees emittance pattern to help optimize stereo imaging. Vocals from quality sources sound more natural and detailed as the center cap and cone profile are geometrically -aligned.

Much technical research has been done to balance the drivers powertrain (cone, cap, coil, and suspension) between its axis of travel and the corresponding center of gravity. The new negative-camber cone facilitates the repositioning of the coil to avoid the need for a traditional rear suspension (spider). Marks new mono suspension design frees the coil form having a restrictive spider bonded to it, improving the transfer of energy from the drivers motor to its cone. The new suspension employs an all-new custom mix of four synthetic materials, resulting in improved linearity under low-frequency loads.

The various slopes and rounded angles help improve sound wave emittance. Custom extended terminals are provided for push-on connectors or light-soldering for cables up to 1.5mm diameter.

The 7MS is an audio driver designed for the dedicated music lover and High-Fidelity enthusiast. Attention to design detail along with a tolerance manufacturing standard to +/- 0.05mm on most component alignments make this new generation of Markaudio transducers stand out from the crowd.
