Hi-Vi M8a, 8" Alloy Cone Woofer

Recommended box 40 liters with 2" Ø vent by 5.1" long for F3 of 32Hz. We would recommend using a flared port on this speaker.

28.3 liters = 1 cubic foot = 1728 cubic inches

• Advanced alloy (magnesium/aluminum) cone, coated with special damping material
• Optimum recovery CONEX supporting system, having good rigidity and dynamic stability, improving the sonic features of the driver.
• High power handling, heat-resistant Kapton? Voice coil former and heat-resistant SV voice coil wire.
• Outside magnetic system with long-throw linear excursion design.
• Hi-Vi Symmetric Motor Drive (SMD) technology makes the voice coil into a symmetrical driving magnetic field, thus acquiring symmetrical driving force, reducing the mutual modulation of voice coil inductance and back electromotive force, improving the controllability of the speakers, achieving low distortion degree.
• Finite Element Analysis for high density aluminum frame, prevents the parasitic structural resonances;

M8a can be used as a bass or midrange in a two-way bookshelf speaker system; or used as a main speaker, center channel speaker, surround speaker, or subwoofer in a home theatre system; it can also be used in multimedia speaker systems. The design of the M8a has been optimized for an extended and dynamic bass reproduction in vented systems. Clarity and accuracy is remarkable. The M8a utilizes our unique one-piece Aluminum/Magnesium composite cone. The cone superior rigidity provides for dynamic and accurate reproduction of transient attacks. This contributes to a more naturally dynamic sound and superior definition and articulation in the mid-bass region. The high temperature voice coil former and SV wire, air transparent spider and venting of the coil allow for good power handling. Using Finite Element Analysis simulation, we optimized the complete magnet structure and specifically shaped the pole piece to achieve symmetric flux distribution along the travel path of the voice coil. This design approach provides better driving force linearity. It considerably reduces voice coil inductance modulation and DC offset of the moving system at high power levels. The result is much less distortion and more effective voice coil cooling. The massive aluminum die-cast basket has been developed to minimize parasitic structural resonances. The M8a provides excellent quality bass definition with good extension (40 Hz). It can be used to good effect in a medium sized two-way system or as a woofer in a three-way system. Incorporated into the Diva line of loudspeakers manufactured by Swans the M8a earned the Exceptional Value Award at The Home Entertainment Show 2000. Recommended crossover frequency region for a two-way system design is 1-2 kHz.
