Product details

The sophisticated design of the TW 104.28 N/Ag begins with its precision-coated silk dome tweeter, which is damped both internally and externally, forming a stable mini-sandwich structure. This effectively eliminates distortion and prevents deformation at high sound pressure levels. The large surround features a special rubber-based coating, further enhancing its stability and elasticity. This is complemented by an aluminum flange and a rear chamber, which not only ensure structural durability but also improve heat dissipation – crucial for demanding audio applications.

In terms of performance, the 1.1-inch voice coil utilizes flat, copper-clad aluminum wire and an aluminum former, ensuring low moving mass and optimal gap filling for excellent impulse response. The neodymium magnet system with a vented magnetic circuit and silver pole cover maintains stable impedance in the high-frequency range and improves compatibility with modern amplifiers. The rear-damped chamber is carefully engineered to minimize resonances, enabling a recommended low crossover frequency of just 1.5 kHz and allowing for seamless and flexible integration with a wide range of loudspeakers.

This dome tweeter impresses not only with its technical specifications, such as its 91.5 dB sensitivity and 25 W AES power handling, but also offers practical advantages during installation. With an overall diameter of 104 mm and a mounting depth of only 37.6 mm, the TW 104.28 N/Ag fits easily into most enclosures. It comes complete with a gasket, mounting screws, and thumb nuts, ensuring a secure and airtight fit. Furthermore, its design is geared towards simplified crossover construction, reducing the impedance peak at resonance and allowing for less complex crossover designs or custom filter solutions.

Perfect for high-end DIY projects and premium audio systems, the RS Speakers TW 104.28 N/Ag is an outstanding component for anyone seeking exceptional detail and transparency in the upper frequency ranges. It's a valuable addition to any audio component collection, whether you're upgrading an existing system or developing a new sound solution from scratch.
