About the Classic 20

The Audio Physic Classic 20 is a premium floorstanding loudspeaker from the Classic series, engineered in Germany with a sophisticated sandwich cabinet construction using MDF inner layers and wood veneers or glass finishes for superior resonance control. It employs a 3-way design with the woofer housed in a dedicated internal compartment near the base, firing downwards via a bass reflex port, minimizing vibrations and delivering powerful, accurate low frequencies. The midrange driver features a fibre-reinforced paper membrane, fixed phase plug, and oversized voice coil for neutral midrange reproduction, while the tweeter with fabric dome and radial felt mat ensures linear high-frequency response up to 30 kHz with uniform dispersion. Additional features include WBT nextgen terminals, interchangeable front panels (open or fabric-covered), and elaborate internal struts to maximize cabinet volume and rigidity. Users praise its spacious soundstage, detailed bass, vocal clarity, and lively presentation across genres.[1][3][4][6][7]
