Eternal 12.5 Bookshelf Speakers

The dual 12-inch woven fiber composite woofers mark Spotless' entry into the large-driver era. This design minimizes distortion, delivers fast low-frequency response, and provides unparalleled bass impact, reaching down to 33Hz (-6dB). Natural rubber surrounds ensure ample headroom for dynamic low-frequency passages.

The 3-inch silk dome midrange driver features a rare-earth neodymium magnet motor for clear, distortion-free vocals. A refined aluminum acoustic rear chamber contributes to a rich, full midrange, while a custom-designed aluminum front horn optimizes directivity. The dual midrange drivers allow for effortless reproduction of the mid-frequency band, surpassing the performance of typical two-way or three-way speakers.

The 1-inch paper cone tweeter utilizes a proprietary fiber formula developed over three years of research. This unique diaphragm delivers a pure and neutral sound, enhanced by an anti-diffraction fiber mat that smooths out high frequencies for a warm, smooth, and engaging listening experience.

The three-way, five-driver crossover network is meticulously engineered for precise sound reproduction. High-quality ERSE metallized polypropylene film capacitors, custom-wound 5N oxygen-free copper air-core inductors, and high-power precision thick-film non-inductive resistors with heat sinks contribute to exceptional transparency, dynamics, and power handling.
