The Audison AV 6.5 is a high-performance mid-bass driver designed to serve as the low-frequency link in two-way speaker systems or as the mid-bass component within a three-way setup. Its 165 mm cone is crafted from pressed cellulose reinforced with cotton fibers and treated with a special water-repellent impregnation for better damping, which helps maintain sound clarity across different environments. To ensure precise movement and reduce artificial coloration in the mid frequencies, the driver utilizes a triple wave Butyl rubber surround. This is supported by an acoustically transparent die-cast aluminum basket that provides structural rigidity without interfering with the audio signal. Inside, an ultra-lightweight double layer CCAW voice coil works alongside a cooling system featuring a central air duct and radial holes to maintain thermal stability during extended use. These technical choices result in high sensitivity and improved impulse characteristics, allowing for a structured reproduction of low frequencies. This makes the speaker a reliable choice for car audio enthusiasts who want to build a detailed sound stage with natural tonal balance.
