Overview

HiVi C6.5 6-1/2" Reinforced Paper Cone Woofer

HiVi C6.5 6-1/2" Reinforced Paper Cone Woofer

The Swan C6.5 mid-bass speaker unit is meticulously engineered to provide audiophiles with exceptional sound quality. Its diaphragm, crafted from a German-imported paper and fiber blend with a marbled surface treatment, ensures natural and accurate sound reproduction. The inclusion of a fatigue-resistant, high-loss natural rubber surround effectively absorbs unwanted vibrations, resulting in clearer audio output.

To minimize distortion during high sound pressure levels, the speaker utilizes HiVi's symmetrical magnetic field (SMD) technology, offering a powerful and linear drive source. The high-density aluminum frame, designed through finite element precision computer simulations, eliminates harmful resonances, contributing to the speaker's structural integrity and longevity. Additionally, the high-power, high-temperature AL voice coil skeleton ensures consistent and high-quality bass performance.

Ideal for use as a low-frequency driver in two-way bass-reflex systems or as a midrange unit in three-way systems, the Swan C6.5 combines advanced materials and innovative design to deliver dynamic and vibrant audio.
