Hybrid Aramid Speaker Cone – Responsive in So Many Ways
New advances present new challenges! The high power of our digital amplifiers demand new speaker solutions to tap their full potential. Our R&D department has responded with a revolutionary hybrid Aramid speaker cone.
Aramid, the Super Fiber
Used in a variety of applications from aerospace to bullet proofbody armor, Aramid is a remarkablesynthetic fiber with amazing strength and other useful properties.To tap these qualities, Panasonic has developed original tech- nology to uniformly mixlong 3mm Aramid fibers in resin. The result is a true hybrid cone material for fabrication of even thinner and lighter diaphragms with high rigidity and uniform characteristics throughout.

Higher Internal Loss for Crystal Clarity
The advent of the Aramid hybrid has brought us closer than ever to realizing the ideal speaker cone. Not only does this new material greatly improve rupture resist- ance, it also allows us to achieve a high internal loss without sacrificing gains in propagation velocity. Thanks to the superior internal loss characteristics (twice that of our previous models), the clarity is astounding, eliminating the muddy sound that plagues conventional speakers.
Light and Super Thin for “Fast” Response
The conventional practice of coating, layering or sand- wiching fibers provides reinforcement at the expense of weight and thinness. With our innovative mixing tech- nology, we can fabricate an extremely lightweight cone that is the thinnest (0.2~0.3mm) in the industry yet still enjoy the benefits of a high degree of stiffness and excel-

lent shape retention. For the listener, this means a speak- er that delivers incredibly fast and smooth response across an extended frequency range, but is durable enough to handle the awesome power of our digital amps. From deep bass to scintillating highs, the quality of the sound imaging is clear and natural.
Extended Cone
Discrete Edge
By adopting a
Discrete Edge Design
By locating the rolled edge of the surround speaker inside and below the outer perimeter of the cone, Panasonic realizes an extended cone and wider effective diaphragm area for improved low frequency response. Edge distortion, which is nor- mally caused by edge radiation, is also reduced.
