    Frequently Asked Questions about Illuminator 15WU/4741T00

    What are the main technical features of the Illuminator 15WU/4741T00?

    The Illuminator 15WU/4741T00 from Scanspeak offers an excellent combination of technology and performance. Notable technical features include the patented sandwich paper diaphragm and the symmetrical drive system (SD-3). A neodymium drive and an underhung voice coil minimize distortion, while the linear excursion allows for exceptional audio quality. With a power handling of 80/150 W and a frequency range of 30 to 3500 Hz, precise and detailed performance is ensured. The effective diaphragm area of 92 cm², combined with a linear excursion of +/- 9 mm, provides comprehensive control over the sound image.

    What frequency range does the Illuminator 15WU/4741T00 cover?

    The Illuminator 15WU/4741T00 is capable of covering a wide frequency range from 30 Hz to 3500 Hz. This makes it an excellent choice for both low and high tones. The resonance frequency at 34 Hz allows for precise reproduction of lower frequencies. Especially in projects that require a wide range of frequencies, this speaker demonstrates its capabilities. Its power handling of up to 150 W also ensures that no detail is lost when the music is played loudly.

    How does the underhung voice coil affect the speaker's performance?

    The underhung voice coil, in conjunction with the neodymium drive of the Illuminator 15WU/4741T00, is crucial for minimizing distortion and achieving precise audio performance. This design keeps the voice coil centered in the magnetic field even at maximum excursion, ensuring a constant force on the diaphragm and thus clearer sound reproduction. This technology is particularly beneficial for high-precision applications, as it reduces distortion and maintains linearity even at high volumes. This guarantees a pure, uncolored sound.

    What advantages does the patented sandwich paper diaphragm of the Illuminator 15WU/4741T00 offer?

    The patented sandwich paper membrane of the Illuminator 15WU/4741T00 optimally combines stiffness and Damping, resulting in low-loss and linear displacement. This special membrane structure allows for a quick and precise response to audio signals, which is particularly important for music lovers who value detailed sound reproduction. The robust construction of the membrane reduces unwanted resonance effects while ensuring dynamic reproduction across all frequency ranges, from low to high tones.

    How does the linear displacement of +/- 9 mm affect sound quality?

    The linear displacement of +/- 9 mm of the Illuminator 15WU/4741T00 is essential for its exceptional performance, especially at lower frequencies. This extensive membrane movement ensures that even at high volumes, the sound remains undistorted and the full dynamics of the audio signal are enjoyed. For audio applications that require high performance and precision, this feature is of essential importance. The combination of linear displacement and other technical characteristics, such as the underhung voice coil, contributes to the overall quality of the speaker and makes it an ideal choice for demanding sound projects.

    What are the installation dimensions of the Illuminator 15WU/4741T00?

    The installation of the Illuminator 15WU/4741T00 requires precise planning due to its specific installation dimensions. The installation diameter is 123 mm, which must be taken into account in existing enclosures or sound walls. The outer diameter is specified as 149 mm, while the installation depth is 97.5 mm. These measurements contribute to a snug fit and must be considered in preparation to ensure optimal seating and thus flawless functionality of the speaker.

    What does the rated sound pressure of 85.9 dB mean for the Illuminator 15WU/4741T00?

    A rated sound pressure of 85.9 dB means that the Illuminator 15WU/4741T00 can produce this volume at a voltage of 2.83 V at a distance of 1 meter. This specification is crucial for assessing the efficiency of the speaker. In practice, this means that the speaker can generate enough sound pressure to be heard well even in larger rooms without requiring extremely high amplifier power. The combination with the low total Qts of 0.23 ensures efficient and accurate reproduction of the audio spectrum.

    What role does the voice coil inductance of 0.5 mH play?

    The voice coil inductance of 0.5 mH is a critical value for the performance of the Illuminator 15WU/4741T00, as it influences how the speaker processes highs and crossover frequencies. A low inductance means that the voice coil can respond quickly, thus improving the reproduction of high frequencies. This reduces the possibility of delays or distortions, especially in the mid to high frequency range. The inductance is therefore particularly relevant for applications that require precise and responsive sound capture and reproduction.

    How can the Illuminator 15WU/4741T00 be integrated into an existing audio system?

    For the integration of the Illuminator 15WU/4741T00 into an existing audio system, the technical specifications such as impedance and power handling are particularly relevant. With an impedance of 4 Ohm, the speaker is suitable for many commercial amplifiers that support such impedance. The nominal power handling of 80 W, with a maximum power handling of 150 W, allows for use in high-power audio systems. Important installation parameters, such as the installation diameter of 123 mm and the installation depth of 97.5 mm, must be precisely planned in advance to ensure seamless integration.

    Does the Illuminator 15WU/4741T00 meet the requirements for a high-end audio project?

    The Illuminator 15WU/4741T00 undoubtedly meets the requirements for high-end audio projects due to its many technical refinements. The combination of a powerful underhung voice coil with neodymium drive, the patented sandwich paper diaphragm, and excellent linear excursion delivers outstanding sound fidelity and clarity. The resonance frequency of 34 Hz and the frequency range of 30-3500 Hz ensure that both low and high tones are reproduced with precision. Together with the stable power handling and overall construction, this woofer is an excellent choice for audiophile applications such as in the studio or ambitious home projects.
