0.75-inch ring radiator: Maximum precision for your system

The 0.75 (19mm) ring radiator of the Scanspeak Automotive Discovery R1904/613001 ensures impressive attention to detail in the high-frequency range. This compact design enables more precise reproduction of high frequencies, making the tweeter particularly suitable for use in high-fidelity systems in the automotive sector. Compared to conventional dome tweeters, the ring radiator achieves greater frequency accuracy and ensures clean separation of the tones. This creates sound images with remarkable transparency and clarity. An alternative design could significantly compromise detail.

4 ohm impedance for efficient performance and integration

With an impedance of 4 ohms, the Scanspeak Automotive Discovery R1904/613001 is designed to work efficiently with modern amplifiers. Low impedance facilitates current flow and ensures the tweeter operates with fewer losses, resulting in a more powerful system overall. The fidelity of the sound remains unaffected even at higher volumes. A higher impedance would require more amplifier power to achieve the same volume, which could place additional demands on the amplifier hardware.

Neodymium magnet system: Compact power in the tweeter

The neodymium magnet system of the ring radiator tweeter provides a strong magnetic field force with minimal volume, facilitating ergonomic design. This compactness is ideal for installation in the confined spaces of a vehicle. Due to the high magnetic flux density, the neodymium material allows for more precise control of the diaphragm's vibrations, resulting in greater clarity and linear performance. This is especially important for seamlessly integrating the tweeter into existing systems and optimizing a vehicle's soundscape.

Patented SD-2 magnet system: Innovative sound experience

The specialized Scanspeak tweeter features a patented SD-2 magnet system designed to maximize distortion-free sound transmission. This advanced technology minimizes the harmonic distortion that can occur at high levels, achieving cybernetic sonic purity. Compared to other systems on the market, the SD-2 system represents a superior choice, maintaining sonic subtleties while enhancing the capabilities for complex automotive audio setups.

Sound-transparent protective grille for undisturbed sound performance

The tweeter's sound-transparent grille not only contributes to the longevity of the system by protecting the diaphragm from physical damage, but also does not compromise sound quality. The special material selection and design of the grille allow unobstructed sound propagation, resulting in a clear and undistorted sound. A less than optimally designed grille could cause inconsistencies in the frequency response and acoustic degradation, thereby diminishing the value of the entire audio component.

Perfect integration through the die-cast housing

The Scanspeak Automotive Discovery R1904/613001's die-cast enclosure provides a solid structure that minimizes vibrations and ensures stable sound performance. This construction also optimizes durability and protects the tweeter's internal components from external influences. This improves overall sound quality and durability.

A less optimized design could result in frequencies being reflected unevenly, distorting the sound and potentially impairing listening enjoyment.

Fs of 1000 Hz: Wide frequency range for comprehensive audio reproduction

The resonant frequency (Fs) value of 1000 Hz demonstrates that the Scanspeak Automotive Discovery R1904/613001 can penetrate deep into the frequency range to create a rich listening experience. A higher Fs would limit the tweeter's ability to cover less of the low frequency spectrum, limiting its use more to mid and high frequencies. Parameters like these are crucial for determining the optimal range of operation in conjunction with other speakers in an audio system to achieve maximum coherence.

Bl value of 1.4 Tm for accurate performance analysis

The tweeter's Bl value of 1.4 Tm indicates a moderate magnetic force acting between the voice coil and the neodymium magnet. A higher value would enable stronger motor performance and therefore more direct sound dynamics, while a lower value might offer less noticeable impulse responses. This parameter is essential for determining how accurately the tweeter reproduces acoustic signals and its overall finesse in the speaker combination.
