Industry's first nanoscale graphene drum paper

Independent research and development, the industry's first nanoscale graphene drum

paper. Graphene material has an atomic layer hexagonal honeycomb structure, which

is stable in structure and has super strong deformation ability. At the same time, it has

a mechanical strength 200 times higher than steel. Marten Taisheng applies graphene

to speaker drum paper and adopts a design of center thickening and gradually thinning

towards the edges, ensuring lower diving depth of the unit while having decent upper

limit performance

Pure aluminum bullet phase plug

Improve frequency response characteristics, prevent standing waves and cross-over

distortion, effectively enhance sensitivity and high frequency, use pure aluminum

material for rapid heat dissipation, enhance overall unit efficiency, and avoid the

impact of temperature rise on sound quality

TIL (fiberglass) voice coil skeleton paired with SV pure copper voice coil wire

Adopting TIL (fiberglass) skeleton, characterized by light weight, strong rigidity, and

better transient response. Not affected by temperature changes in physical properties,

better stability

Original shockwave lead design and gold-plated terminal block

Abandon the traditional lead method and avoid the lead attaching to the drum paper,

which may cause an imbalance in weight distribution. Gold plated terminal blocks

have excellent qualities such as anti-oxidation, high fidelity, reduced transmission

attenuation, and stable signal transmission, restoring lossless sound quality

Marton Taisheng's original cooling system

Adopting high-quality precision cast aluminum basin frame, innovative patented

design, 360 degree all-round heat dissipation, effectively reducing thermal attenuation

and maintaining high performance of the unit

Chrome plated thickened inclined back magnetic circuit high-performance aerospace

Y35 magnetic steel

Using high-performance aerospace magnetic steel, in order to further enhance magnetic

performance, this unit adopts a fully integrated long stroke magnetic circuit with a cost

several times higher than that of ordinary split magnetic circuits. It adopts a chrome

plated thickened inclined back magnetic circuit with a center thickness of up to 15mm,

effectively improving magnetic performance
