TS-A300D4 Subwoofer: Powering up your sound

Engineered specifically to provide drivers with punchy bass that allows for a full-sounding audio experience. A Series subwoofers come packed with improved technologies developed specifically to go above and beyond the competition, such as a highly rigid IMPP composite cone, high compliance rubber rolled edges, and dual spiders.

Glass Fiber and Mica Reinforced IMPP Cone

The Glass Fiber and Mica Reinforced IMPP Cone enhances the cone’s rigidity, reducing flexing and distortion for accurate sound reproduction. It also improves transient response for faster and more precise bass notes, provides better damping properties, minimizes unwanted vibrations and delivers cleaner sound. The cone’s thermal stability is also enhanced, preventing deformations during high-power use. This result in improved reliability and performance.

Large Size Double Stacked Magnet with Vented Backplate

The 60oz large size magnet used in TS-A300 helps to facilitate a better low-frequency response. The increased motor force enables the speaker to move the cone with greater precision and authority, resulting in improved bass reproduction, deeper extension, and increased overall output capability in the low-frequency range. The double stacked magnet configuration increases the total magnetic flux within the subwoofer’s motor assembly. This stronger magnetic field provides greater force and control over the voice coil, allowing for improved linearity, cone control, and overall efficiency.

4-Layer Cooper Voice Coil

The 4-layer voice coil wire configuration enhances power handling, thermal management, and magnetic field strength compared to dual-layer coils. While copper has higher electrical conductivity than aluminum, which leads to lower resistive losses and more efficient copper has higher electrical conductivity, which leads to lower resistive losses and more efficient power transfer. This allows for improved power handling capabilities and overall system efficiency. t power transfer. This allows for improved power handling capabilities.
