Frequently Asked Questions about EBS108A

Wie lässt sich der EBS108A in die Reserveradmulde einbauen?

The EBS108A from Emphaser fits perfectly into the spare wheel well or the spare tire with its installation depth of 145 mm and an installation diameter of 360 mm. To install it, you place it in the well, connect the power cables via the integrated terminal block, and connect it to the car radio using the RCA or high-level inputs. The external bass level remote control allows you to conveniently adjust the bass level from inside the vehicle. The included mounting kit makes it easier to securely attach the subwoofer in the well, ensuring trouble-free operation.

Welche Frequenzbereiche deckt der EBS108A von Emphaser ab?

The EBS108A active enclosure subwoofer from Emphaser covers a frequency range of 30 Hz to 180 Hz. This allows for deep, resonant bass reproduction ideal for music genres where bass plays a central role. The integrated variable low-pass filter from 50 Hz to 150 Hz and the subsonic filter at 20 Hz with a slope of 12 dB/octave support clear and clean bass reproduction. The switchable phase makes it easier to adjust the subwoofer to the acoustic environment to eliminate phase issues and ensure the best possible sound.

Wie arbeitet der integrierte Class-A/B MOS-FET Verstärker im EBS108A?

The integrated Class A/B MOS-FET amplifier of the EBS108A from Emphaser provides efficient and powerful amplification of the bass signal. With a rated power of 150 W RMS, this amplifier can handle peak power up to 300 W. These power parameters ensure strong and clear reproduction of bass, which is essential in many music genres. The amplifier operates with a signal-to-noise ratio of over 90 dB, providing noise suppression that ensures precise, distortion-free sound.

Was bietet der regelbare Bass Boost des EBS108A von Emphaser?

The EBS108A features a variable bass boost that allows for an increase from 0 dB to 12 dB at 45 Hz. This ensures that you can raise the bass according to your preference or music genre to emphasize or adjust it. It is particularly useful for creating more bass presence in acoustically challenging environments. Especially if you enjoy listening to music at high volumes, the bass range can be adjusted to create a harmonious and balanced sound image while taking personal preferences into account.

Welche Verbindungsmöglichkeiten bietet der EBS108A für Audioquellen?

The EBS108A active subwoofer offers two main connection methods: the RCA inputs with a sensitivity of 0.4 V and the high-level inputs at 1.0 V. This flexibility makes it easy to connect the subwoofer to both aftermarket and factory car radios. Thanks to the auto turn-on feature, the subwoofer automatically powers on as soon as an audio signal is detected. This enhances user-friendliness and convenience, as no manual activation is required, which is particularly advantageous in the car.

Verfügt der EBS108A über eine Phaseneinstellungsmöglichkeit?

Yes, the EBS108A from Emphaser features an adjustable phase shift that can be switched between 0° and 180°. This function allows the user to effectively compensate for potential phase issues that can occur with concurrently started speakers. The optimal sound is achieved by improving the integration of the bass signal with the other speakers in the system. During installation, you can directly adjust the phase to achieve the best possible sound quality, especially in critical system configurations.

Welche Steuerungsmöglichkeiten bietet der EBS108A durch die externe Fernbedienung?

The external bass level remote control included with the EBS108A from Emphaser allows for convenient bass adjustment from the driver's seat. With this remote control, you can individually adjust the bass level without having to access the subwoofer directly. This is especially useful while driving, allowing you to quickly respond to different music genres or acoustic requirements. With the remote control, you can ensure that the bass is always optimally tuned without having to focus on the actual subwoofer in the meantime.

Wie unterstützt der Subsonic-Filter des EBS108A die Klangqualität?

The EBS108A is equipped with a subsonic filter at 20 Hz, which operates with a slope of 12 dB/octave. This filter removes inaudible and potentially harmful subsonic frequencies that could overload the subwoofer. Additionally, it prevents unnecessary low-frequency vibrations from spreading the sound broadly. With the subsonic filter, the amplifier's energy remains reserved for the audible frequency range, improving overall sound quality. The filter also helps reduce distortion caused by excessive linear diaphragm displacement.

Welche technischen Aspekte der EBS108A Inbetriebnahme sollten beachtet werden?

For the commissioning of the EBS108A from Emphaser, the power specifications of the vehicle should be taken into account to achieve optimal results. The powerful subwoofer has an impedance of 2 ohms, ensuring that enough power is provided without overloading the electrical system. Given the Auto Turn-On function, integration into the car's electrical system is relatively simple, as no additional control cable is required. The presence of a power connector block allows for easier connection of power supply and ground through standardized pre-installation.

Welche besonderen Akustik-Eigenschaften besitzt der Langhub-Basstreiber des EBS108A?

The 8'' long-stroke bass driver of the EBS108A from Emphaser offers specific acoustic properties tuned to low frequencies. Due to its long stroke capability, the driver is able to generate powerful bass waves with reduced distortion. This makes it ideal for applications where maximum bass presence is desired. The design as a bass reflex system allows for the enhancement of sound pressure at low frequencies and the extension of the frequency response under optimal enclosure conditions. These characteristics make the EBS108A predestined for use in demanding acoustic environments, both in vehicles and stationary.
