Frequently Asked Questions about Revelator 23W/4557T00

What is the power handling of the Scanspeak Revelator 23W/4557T00 Subwoofer?

The Scanspeak Revelator 23W/4557T00 has a power handling of 225 watts. This power is crucial if you plan to use the Subwoofer in a high-performance audio setup, especially in home theater systems or music productions. The power handling plays a central role in minimizing distortion under high load and ensuring consistent sound quality. Even at peak volumes, the Subwoofer maintains its acoustic integrity. If you enjoy listening to music at high volumes, a Subwoofer with high power handling is essential to fully exploit the dynamic range of the music.

What frequency range does the Scanspeak Revelator 23W/4557T00 cover?

The frequency range of the Scanspeak Revelator 23W/4557T00 is between 20 Hz and 800 Hz. This wide frequency range allows the Subwoofer to reproduce deep bass as precisely as mid frequencies, making it particularly versatile. Whether you prefer a powerful bass hit or detailed mids for a balanced sound, the frequency range covers all of this. The frequency response is well-tuned, which is particularly supported by the patented symmetrical drive motor construction to minimize distortion and maximize clarity.

What impedance does the Scanspeak Revelator 23W/4557T00 have?

The Scanspeak Revelator 23W/4557T00 Subwoofer has an impedance of 4 Ohm. This impedance is crucial for compatibility with Amplifiers and receivers. A 4-Ohm impedance means that the Subwoofer draws more current at the same signal, contributing to higher volume and stronger bass. When connecting to an amplifier, it is important that it can handle 4-Ohm speakers to avoid overloads and distortion. A suitable amplifier brings out the full potential of the Subwoofer.

Which car models is the Scanspeak Revelator 23W/4557T00 compatible with?

As no specific car brands are mentioned in the product description, the focus should be on the dimensions. The installation diameter is 225 mm and the installation depth is 141 mm, which is suitable for many vehicles that have space for an 8-inch Subwoofer. However, an accurate measurement of the available space in the car is essential. These dimensional properties make the Subwoofer suitable for both sedans and larger models, provided there is enough space. Adjustments to the enclosure or boxes may be necessary to ensure a precise installation.

What role does the ferrite magnet system play in the Scanspeak Revelator 23W/4557T00?

The ferrite magnet system in the Scanspeak Revelator 23W/4557T00 is crucial for generating strong and precise bass. It stabilizes the voice coil and ensures effective magnetic force distribution, which significantly contributes to reducing distortion. The rubber coating of the magnet system also serves to dampen vibrations. In combination with the rubber surround, the diaphragm movement is controlled, and the sound quality at high volumes is improved without any tonal distortions.

Why is the diaphragm of the Scanspeak Revelator 23W/4557T00 so important?

The aluminum diaphragm of the Scanspeak Revelator 23W/4557T00 plays a critical role in sound reproduction. With a diameter of 9 inches, it provides a large surface area for producing deep bass without distortion. Aluminum combines strength and lightness, leading to a quick and precise response to signals. The diaphragm properties are further enhanced by the patented symmetrical drive technology, contributing to outstanding sound resolution. Especially at high volumes, the sound remains clear and clean, which is particularly appreciated by audiophiles.

What does the resonance frequency of 21 Hz mean for the Scanspeak Revelator 23W/4557T00?

The resonance frequency of 21 Hz in the Scanspeak Revelator 23W/4557T00 indicates the ability to efficiently reproduce very low frequencies. A low resonance frequency means that the Subwoofer can produce very deep, powerful bass, which is crucial for reproducing bass-heavy music pieces and effects in movies. This resonance frequency, combined with the overall wide operating frequency range of 20 Hz to 800 Hz, ensures that the Subwoofer performs excellently in both home theaters and high-end audio environments.

What advantages does the aluminum die-cast basket offer for the Scanspeak Revelator 23W/4557T00?

The aluminum die-cast basket of the Scanspeak Revelator 23W/4557T00 offers several advantages. It provides high structural rigidity, which reduces vibrations and supports the linear displacement of the diaphragm. Additionally, the basket offers excellent heat dissipation, increasing the thermal load capacity of the subwoofer. Furthermore, the ventilation under the centering spider improves the cooling of the voice coil, enhancing electromechanical efficiency. This combination of features significantly supports the durability and performance of the subwoofer.

What is the optimal enclosure size for the Scanspeak Revelator 23W/4557T00?

The optimal enclosure size for the Scanspeak Revelator 23W/4557T00 depends on the desired bass characteristics. A sealed enclosure of 22 liters provides precise bass reproduction with an optimal -3 dB frequency at 35 Hz. Alternatively, an 89-liter bass reflex enclosure can be used to achieve an extended deep bass range down to 16 Hz. Using an HP70 port with a length of 32 cm optimizes airflow and reduces port noise. These options allow for flexible bass adjustment to personal preferences and/or spatial conditions.

How does the force factor (BL) affect the performance of the Scanspeak Revelator 23W/4557T00?

The force factor BL of 9.3 N/A of the Scanspeak Revelator 23W/4557T00 is an indicator of the electromagnetic force acting on the voice coil. A higher BL value indicates stronger magnetic control over the voice coil, allowing for more precise movement and lower distortion. This significantly improves bass accuracy, especially at higher volumes. The BL value is a crucial parameter for the efficiency of the subwoofer's drive system, which is further optimized by the patented symmetrical drive motor design.
