Frequently Asked Questions about Signum SL300A


What are the dimensions of the Signum SL300A?

The Signum SL300A from ESX has compact dimensions of Ø 375 x 110 mm, allowing it to fit into the spare wheel well of small vehicles. Its size is perfectly tuned to fit in the limited space of these vehicle types without compromising performance. Despite its compact size, it delivers powerful bass reproduction through its encompassing sound spectrum and the integrated Amplifier. The architecture of the enclosure supports placement in small vehicles and provides excellent sound damping with its ABS plastic construction. Its dimensions favor both user-friendly installation and quick removal.

What type of Amplifier is integrated into the Signum SL300A?

The Signum SL300A features an integrated Class A/B Amplifier specifically designed to amplify low frequencies in the active Subwoofer. The Amplifier provides 100 watts RMS power and reaches up to 200 watts in maximum power. The Class A/B Amplifier combines the advantages of Class A and Class B topologies to ensure both high output power and good sound with low distortion. Given these specifications, the Amplifier offers sufficient power reserves for dynamic music playback and ensures a balanced sound image. Technically inclined music lovers will appreciate the powerful sound.

How can the Signum SL300A be installed in the car?

The Signum SL300A is explicitly designed for installation in the spare wheel well of small vehicles, making it easy to install. Its dimensions of Ø 375 x 110 mm allow for a smooth fit in the spare wheel area. The Subwoofer does not require special frames or mounts, as the robust ABS plastic enclosure provides optimal stability and damping. The installation of two additional speakers can be done via the stereo Amplifier outputs, ensuring correct polarity is observed. A detailed manual facilitates the installation process to quickly create the high-quality bass experience.

What connections does the Signum SL300A have?

The Signum SL300A is equipped with various connection types that allow for flexible integration into existing systems. The Subwoofer offers high-level inputs as well as RCA inputs, which are accessible via a Molex connector. This variety of inputs allows for direct connection to factory radios or aftermarket radios that provide RCA outputs. These connection options enable the Subwoofer to seamlessly fit into different audio configurations. For the user, this means less effort in integration, as no additional adapters or complicated conversion techniques are necessary.

What power do the speaker outputs of the Signum SL300A provide?

The Signum SL300A from ESX is equipped with stereo amplifier outputs that allow for the connection of two additional speakers. The output power of these channels is specified at 35 watts RMS and up to 50 watts maximum power per channel, which is sufficient to produce a balanced and strong sound even for the satellites. This functionality makes the Subwoofer not only a bass specialist but also a versatile sound system that supports various speaker configurations. Users can expand additional sound fronts or provide existing vehicle speakers with more power to create a comprehensive sound image.

How does the bass level remote control of the Signum SL300A work?

The Signum SL300A offers a bass level remote control that allows you to conveniently adjust the bass level of the Subwoofer from inside the vehicle. This remote is designed to allow for quick adjustments without having to physically go to the Subwoofer. This feature is particularly practical when you frequently switch between different music genres that require varying bass intensities, or when the acoustic requirements change due to the driving conditions. This allows you to dynamically control the sound, contributing to comfort in the car. The remote easily integrates into the interior.

What frequency ranges does the Signum SL300A support?

The frequency range of the Signum SL300A from ESX is specifically designed to cover optimal deep sounds. The low-pass filter (LPF) is adjustable from 50 to 150 Hz, allowing for fine-tuning of the low frequencies. The subsonic filter is set at a fixed value of 25 Hz to filter out unwanted subsonic frequencies that could potentially be harmful and distort acoustic playback. More precisely, this tuning makes the Subwoofer versatile and powerful, especially in music styles that benefit from deep, precise bass. Customized fine-tuning enhances the musical experience.

What materials characterize the Signum SL300A?

The Signum SL300A from ESX impresses with a robust housing made of ABS plastic, a material known for its excellent damping ability and durability. This choice of material not only supports the longevity of the Subwoofer but also ensures optimal sound quality by minimizing vibrations and resonances. The design of the housing is intended to be both lightweight and durable, resulting in an overall weight of just 2.8 kg. With this combination of materials, the Subwoofer targets users looking for a resilient yet lightweight audio system.

What types of vehicles are compatible with the Signum SL300A?

The Signum SL300A is ideally suited for integration into small vehicles due to its designed dimensions, especially in their spare tire wells. If you own a vehicle with a spare tire well, there is a high likelihood that the Subwoofer is compatible. Universal integration is made possible as there are no specific requirements regarding brand or model. However, the size of the spare tire should be considered to ensure that the available space is sufficient, particularly in vehicles with non-standard dimensions. It is advisable to check the measurements of both the vehicle and the Subwoofer before purchase.

What advantage does the automatic power-on feature of the Signum SL300A offer?

The automatic power-on feature of the Signum SL300A significantly enhances convenience by automatically activating the audio system as soon as the car radio is turned on. This function is achieved by detecting an input signal at the high-level inputs and eliminates the need for a separate power switch. This automation promotes convenience by preventing the unwanted omission of the system and optimizing user-friendliness, especially when you want to start quickly. Additionally, the feature ensures that the Subwoofer interacts efficiently with the onboard power supply, reducing overall energy consumption and supporting longevity performance.
