Audio Physic Classic 10 Loudspeaker

SKU: 2034 Category:


The cabinets of the CLASSIC loudspeakers are a fundamentally new development and one of a kind. The body consists of three layers with various dampening characteristics and different levels of stiffness. The result, a sandwich cabinet, has a thickness of 20 millimetres and possesses acoustic characteristics of significantly greater design diameters. A major advantage of the three-layer wall is the dramatic reduction in sound permeability, especially in medium frequencies. For the stiffness of the cabinet is not the sole factor that is acoustically relevant; also how much inwardly-emitted sound escapes outside through the walls. A heterogeneous sandwich is significantly more successful at dampening this sound than a uniformly dense material, and at the same time it is effective in eliminating partial vibrations. All in all, these AUDIO PHYSIC new designs achieve a minimum of resonance and thus a minimum of intrinsic sound previously considered unattainable in this price range.

Ideal conditions for the also newly developed chassis of the CLASSIC 10. The cones for low and medium frequencies are symmetrically arranged around the tweeters. This creates uniform distribution of pressure on the cabinet; best prerequisites for precise sound reproduction, combined with a superb location of instruments and artists.

In the bass, the cone chassis work in tandem and create a powerful foundation full of depth. The surround and drive of the chassis allow the suspension system greater linear lift and thus, even in booming surround applications, afford stunning reserves for a high-fidelity performance. The phase plug of the woofer is firmly attached, thus it does not vibrate with the membrane to the beat of the music. An elaborate structural shape, but one which drastically reduces compression effects behind the membrane. Effects that especially in the mid-range would otherwise lead to imprecision in signal fidelity. The design improves the dissipation of heat from the moving system. Heat accumulation would alter the physical parameters of the system, and the consequences can usually be seen in lethargic sound, lacking definition.

The actual woofer is located beneath the tweeter dome. It is equipped with a generously-dimensioned drive and a four-layer copper voice coil. This is how we achieve optimal power conversion and an exact displacement of the membrane. The star-shaped acoustic panel around the tweeters facilitates uniform sound dispersion. This allows the high-performance fabric dome to fully develop its capabilities – far beyond the audible range of the human ear.
