In 1999, Swans manufactured M5N woofer with original and beautiful appearance, which is suitable for digital audio and sound signal linear loudspeaker system, which is dynamic and with low distortion. This design has laid another landmark of Swans loudspeaker. -Advanced alloy (magnesium and aluminum) cone, coated with special damping material -Optimum recovery CONEX supporting system, having very good stiffness and dynamic stability, improving the acoustic features of the speakers. -High power handling, heat-resistant Kapton?voice coil former and heat-resistant SV voice coil wire -Finite Element Analysis for shielded 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 -Using leading technology of Small/Thiele parameters The design of the M5a has been optimized for an extended and dynamic bass reproduction in small vented systems. Midrange clarity and accuracy is remarkable. The M5a utilizes our unique one-piece Aluminum/Magnesium composite cone. The cone?s superior rigidity provides for dynamic and accurate reproduction of transient attacks. This contributes to a more naturally dynamic sound. The back of the cone is hand coated with a special dampening compound to further maximize performance stability and control of structural resonances. 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. A shielded magnet structure allows the M5a to be easily incorporated into audio/video applications. The driver may be used in a small closed box as a midrange unit in a three-way system and the good extension (50 Hz) in a vented enclosure allows for use in a two-way two-driver or MTM configured system. Incorporated into the Diva line of loudspeakers manufactured by Swans the M5a earned the Exceptional Value Award at The Home Entertainment Show 2000. Recommended crossover frequency region for a two-way system design is 2-5 kHz.

P:M:K integrative copper 3" VC die cast aluminium frame inner magnetic structure neodymium high power mid bass driver 6 holes

The Euro-American nation develops in the loudspeaker up has been be placed in a leading position. 10 years ago, Hi-Vi engineers hope to look for a break, which will make Chinese people also can design a new generation loudspeaker with high index and performance by ourselves. At that time our springboard is to design a small caliber loudspeaker, using a small box can produce a very grand low-midrange sound field. Its voice should be neutral and nobler, it also should be a modern art article. Now this D series loudspeaker basically achieve our original conceive, the D series loudspeaker adopted the latest design in a series of world new concept. Shallow mineral filled polypropylene cone; Specially made high loss rubber surround; Shielded vented magnet system with Neodymium magnet; Long-throw symmetrically driving motor structure with linear excursion increased up to 5.3 mm; High power handling voice coil with 76 mm Kapton?former; High density aluminum die-cast frame; D6.8 represents a design where the voice coil is positioned over an undercut central pole piece with large thermally stabilized Neodymium magnet at the bottom. A specially shaped, CNC machined steel cup completes the magnetic structure from the outside, creating a shielded magnet system with symmetrical flux density distribution along the gap. The long-throw voice coil experiences a symmetric driving force and substantial decrease of inductance and back electromotive force modulations. The whole magnet structure is optimized using Finite Element Analysis. The result is a radical improvement of driver linearity. The cone has a shallow, high integrity structure, which is extremely rigid and dynamically stable. The large voice coil diameter allows more uniform cone excitation, thus improving phase and transient characteristics of the driver, resulting in clear and accurate reproduction. The vented design and a high temperature rated voice coil provide a dramatic increase of power handling. D6.8 is suitable for a wide variety of vented box systems. This driver is capable of delivering the deepest possible base for a minimonitor speaker. It also may be incorporated in a small (6-7l) enclosure as a bass-midrange driver, when a subwoofer is employed.

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.

The design of the F8 has been optimized for balanced and dynamic low bass reproduction in compact or medium vented systems. Midrange clarity and tonal balance is remarkable. The F8 utilizes a newly developed matrix of Kevlar and paper fibers. As a result the cone weighs less, is more rigid, and has an improved dampening factor over conventional Kevlar?materials. The back of the cone is hand-coated with a special dampening compound to further maximize performance stability and control of structural resonances. The driver utilizes a vented Kapton?voice coil former and air transparent spider to avoid air compression and ensure maximum power handling. The massive aluminum die-cast basket has been developed to minimize parasitic structural resonances. A shielded magnet structure allows the F8 to be easily incorporated into audio/video applications. Recommended crossover frequency for two-way system design is 1.8-2.2 kHz.
