This combination ensures minimal distortion while providing excellent sound fidelity. Particularly impressive is the exceptionally large linear excursion across a frequency range of 28 to 3500 Hz. With a power handling of 80/150 W, this speaker is ideal for audio enthusiasts who value precise and high-quality sound technology. A lossless linear suspension further optimizes sound reproduction.

    What power does the Scanspeak Illuminator 18WU/4741T00 offer?

    The Scanspeak Illuminator 18WU/4741T00 has a power handling of 80 W nominal power and 150 W music power, which means it delivers consistent and clear audio output at both moderate and high volumes. The impedance is 4 Ohm, making it a versatile speaker for various audio setups. Additionally, it achieves a sensitivity of 87.2 dB at 2.83V at one meter, contributing to its robust and precise sound reproduction. These performance characteristics ensure excellent output and sound quality.

    What is the resonance frequency of the Scanspeak Illuminator 18WU/4741T00?

    The Scanspeak Illuminator 18WU/4741T00 has a resonance frequency of 30 Hz. This low resonance frequency is ideal for reproducing deep bass and seamlessly fits into the frequency range of 28 to 3500 Hz. The precise construction with the patented underhung voice coil system creates harmonious sound reproduction across its entire bandwidth and minimizes distortion. This resonance frequency is particularly interesting for audio enthusiasts who prefer bass-heavy sounds and place great value on faithful reproduction.

    What technologies does the Scanspeak Illuminator 18WU/4741T00 use for the highest sound quality?

    The Scanspeak Illuminator 18WU/4741T00 combines several innovative technologies to enable the highest sound quality. A unique feature is the patented sandwich paper diaphragm, which ensures clear and distortion-free sound reproduction. This is complemented by the underhung voice coil system with neodymium drive, which helps minimize distortion while guaranteeing an exceptionally large linear excursion. These technical features, along with the low-loss linear suspension, allow for accurate and authentic sound reproduction that will impress even the most demanding audiophiles.

    What are the dimensions of the Scanspeak Illuminator 18WU/4741T00?

    The Scanspeak Illuminator 18WU/4741T00 has specific installation dimensions that must be considered: the cutout diameter is 158 mm, the outer diameter is 184 mm, and the mounting depth (not recessed) is 105 mm. These measurements ensure that the speaker can be flexibly integrated into various enclosure designs. When installing, it is important to adhere to these dimensions precisely to ensure the optimal function and sound quality of the speaker. It is crucial to consider this during installation to allow space for the linear excursion.

    Can the Scanspeak Illuminator 18WU/4741T00 be compatible with various car audio systems?

    The Scanspeak Illuminator 18WU/4741T00 will be compatible with a variety of car audio systems due to its 4 Ohm impedance and flexible cutout diameter of 158 mm. However, before installation in a vehicle setup, it should be ensured that space and enclosure can be accommodated to carry out the installation effectively. The outer diameter of 184 mm and the mounting depth of 105 mm are critical for compatibility with different vehicle types. Such measurements are typical for many car installations, but always check the vehicle manual.

    What specific parameters influence the sound quality of the Scanspeak Illuminator 18WU/4741T00?

    The Scanspeak Illuminator 18WU/4741T00 achieves outstanding sound quality through its selected Thiele Small parameters: The free-air total Qts of 0.29, combined with a force factor BL of 6 N/A and a voice coil inductance L of 0.5 mH, ensures precise and dynamic bass reproduction. The DC resistance Re is 3.2 Ohm, contributing to the balance between amplifier control and speaker movement. Combined with an effective diaphragm area Sd of 154 cm², these parameters will significantly influence the frequency response and reaction time of the driver.

    What role does the patented symmetrical drive (SD-3) play in the Scanspeak Illuminator 18WU/4741T00?

    The symmetrical drive (SD-3) in the Scanspeak Illuminator 18WU/4741T00 plays an important role in the sound design of the speaker. By using this patented drive, a particularly linear magnetic field is generated, which moves the voice coil symmetrically and efficiently. This minimizes distortion and improves the overall dynamics of audio playback. The SD-3 drive works in combination with the sandwich paper diaphragm to enable homogeneous sound propagation. This technology is particularly relevant for fine dynamics and sound purity in high-quality audio playback systems.

    What describes the exceptionally large linear excursion of the Scanspeak Illuminator 18WU/4741T00?

    The Scanspeak Illuminator 18WU/4741T00 has an exceptionally large linear excursion of +/- 9 mm. This capability is crucial for low-frequency reproduction, as larger excursions move more air, resulting in a rich and full bass sound. This is achieved through the interplay of neodymium drive and underhung voice coil. The linear excursion plays a vital role in minimizing distortion and defining sound imaging at high volumes.

    How does the low-loss linear suspension affect the performance of the Scanspeak Illuminator 18WU/4741T00?

    The low-loss linear suspension in the Scanspeak Illuminator 18WU/4741T00 significantly contributes to the musical precision and longevity of the speaker. This suspension minimizes mechanical losses and allows the diaphragm to move more precisely, which is essential for outstanding sound fidelity. Especially at high volumes, the speaker remains linear and controlled. The linearly operating suspension allows for extensive excursion without compromising sound integrity, which is crucial for audio enthusiasts with high demands for detail and vitality in the sound image.
