Frequently Asked Questions about Quantum Q168A

What are the dimensions of the Quantum Q168A from ESX?

The Quantum Q168A is a compact 6"x8" active enclosure Subwoofer with dimensions of 195 mm in width, 74 mm in height, and 260 mm in depth. These measurements allow for versatile placement, such as under or behind car seats, to ensure optimal space utilization, especially in small cars, sports coupes, and convertibles. With its specific dimensions, it fits perfectly in tight spaces without compromising sound quality, making it an ideal choice for vehicles with limited space. Thanks to this compactness, there is also enough room for other items or accessories in the vehicle.

What performance specifications does the Quantum Q168A Subwoofer achieve?

The Quantum Q168A from ESX offers remarkable performance with an integrated Class A/B Amplifier that reaches 1 x 100 Watts RMS and 200 Watts maximum power. This capability ensures clear sound reproduction and powerful bass, ideal for music lovers. The Amplifier supports precise sound control through a variable low-pass filter (LPF) from 50 to 150 Hz. Additionally, a bass boost of 0 to 12 dB at 45 Hz is available, allowing users to adjust the bass to their individual preferences, which makes a significant difference, especially in smaller vehicles.

How does the bass level remote control work with the Quantum Q168A?

The bass level remote control of the Quantum Q168A allows for comfortable and precise adjustment of the bass level while driving. This mobile control, connected via a simple cable, enables the user to adjust the bass from the front of the car without needing to reach the Subwoofer in the trunk or under the seat. Especially if you enjoy listening to loud music and want to adjust the bass according to the music style or volume, this feature offers significant flexibility. The remote also facilitates fine-tuning and ensures optimal bass reproduction at all times.

What inputs does the Quantum Q168A from ESX offer?

The Quantum Q168A is equipped with both high-level and RCA inputs, making it versatile and flexible in connectivity. The high-level inputs allow for direct connection to speaker outputs, ideal for cars without separate pre-outs. RCA inputs are standard for connecting to a stereo system that supports these jacks, greatly simplifying integration into existing systems. These dual connection options ensure that the Subwoofer can be integrated into a variety of audio systems without compromising sound quality.

What special features does the Quantum Q168A have regarding sound optimization?

The Quantum Q168A offers several features for sound optimization. This includes the Bass Boost, which allows for a boost of up to 12 dB at 45 Hz to tailor the sound to personal preferences. Additionally, there is the Phase Shift function with settings of 0/180° to address phase issues with other speakers. A subsonic filter at 30 Hz protects the driver from unwanted ultra-low frequencies that may come from music sources. These features work together to achieve the most precise and powerful bass reproduction possible.

How is the Quantum Q168A from ESX installed in the car?

The installation of the Quantum Q168A in the car is done through a space-saving mounting under or behind a car seat or in the trunk. With its compact dimensions of 195 x 74 x 260 mm, installation in small spaces is straightforward. The integrated Class A/B Amplifiers and connection options via high-level or RCA inputs significantly simplify integration into existing vehicle audio systems. For power supply, the Subwoofer is directly connected to the car battery, ensuring constant performance without fluctuations. This allows for user-friendly handling and optimal sound quality.

What advantages does the robust aluminum die-cast heat sink of the Quantum Q168A offer?

The aluminum die-cast heat sink of the Quantum Q168A ensures efficient heat dissipation by directing unwanted heat away from the Amplifier, preventing overheating. This is particularly important at high levels, where a lot of energy is continuously converted. With effective cooling, the Subwoofer can perform optimally during power peaks without triggering protection shutdowns or failures. This not only guarantees a longer lifespan for the device but also consistent performance, especially during intense use. Thus, the sound quality of the Subwoofer remains at a consistently high level.

What does the automatic power-on function do for the Quantum Q168A?

The automatic power-on function of the Quantum Q168A detects the music signal as soon as the car's main amplifier is activated and automatically turns on the Subwoofer. This function not only contributes to energy efficiency by avoiding unnecessary power consumption when not in use, but also simplifies operation, as the user does not need to intervene manually. It ensures that the Subwoofer is only operational when truly needed, which increases its lifespan and enhances everyday comfort. This function is particularly useful in complex audio systems where manual controls are hard to access.

What frequencies are processed by the Quantum Q168A?

The Quantum Q168A processes a range of frequencies thanks to its variable low-pass filter (LPF), which can be adjusted between 50 and 150 Hz. This allows for targeted adjustment of frequency limitations, so the Subwoofer can sound optimal in different environments. The built-in subsonic filter blocks just below 30 Hz to eliminate unwanted low frequencies that could potentially damage the speaker. By amplifying only the audible bass and reducing harmful frequencies, the Subwoofer provides precise bass reproduction.

Is the Quantum Q168A compatible with common car brands and models?

Yes, the Quantum Q168A is compatible with most car brands and models thanks to its compact size and universal connection options. Specifically designed for limited space in small cars, sports coupes, and convertibles, it can be flexibly mounted under or behind seats. However, it is advisable to check the dimensions of the installation location in the vehicle beforehand to ensure that the Subwoofer can be optimally accommodated. The flexible connection via high-level and RCA inputs ensures that the Subwoofer can be connected to a variety of different audio systems.
