The Quantum Q201A subwoofer from ESX features an integrated Class A/B amplifier power of 100 watts RMS and can achieve a maximum power of 200 watts. This power allows for deep and powerful bass to be produced in compact vehicles such as small cars, sports coupes, and convertibles. The specification is ideally matched to the acoustic volume of such vehicles. With its special 20 cm woofer, a balanced sound quality is provided, which can be further optimized through the bass boost and the flexible LPF frequency adjustment between 50 and 150 Hz. This allows the subwoofer to be precisely tuned to specific music genres.
The Quantum Q201A subwoofer has compact dimensions of 210 x 73 x 290 mm, allowing for flexible installation. The low height of 73 mm makes it easy to place the subwoofer under or behind car seats. Alternatively, it can also be stored in the trunk compartment. This is particularly advantageous for small cars, sports coupes, and convertibles, as it requires little storage space. The adaptability of its placement offers versatile installation options to optimize sound performance to match the acoustic conditions of the vehicle. This way, the interior aesthetics remain untouched.
The Quantum Q201A subwoofer is equipped with versatile connection options. It features high-level and RCA inputs that allow for easy integration into existing audio systems. The use of the high-level inputs is particularly suitable for factory car radios without RCA outputs, while the RCA inputs are compatible with aftermarket radios. The subwoofer also has an automatic power-on function that activates the device as soon as a signal is received. This feature optimizes user-friendliness and ensures that the subwoofer is seamlessly and efficiently integrated into the vehicle's sound system.
For optimal sound design, the Quantum Q201A offers several adjustment options. It features a variable low-pass filter (LPF) adjustable from 50 to 150 Hz, allowing for frequency range adjustment. The bass boost of 0-12 dB at 45 Hz allows for individual bass enhancement to emphasize strong, deeper tones. The bass level remote control allows the volume to be adjusted directly from the vehicle's interior to optimally match the sound intensity to personal preferences. These features ensure that the subwoofer can be individually adjusted according to the preferred music style.
The ESX Quantum Q201A subwoofer uses a die-cast aluminum heat sink that ensures effective heat dissipation. This heat sink ensures that the integrated Class A/B amplifier can operate efficiently without being affected by overheating. Especially at higher volumes and over longer operating times, the subwoofer remains reliable and stable in its performance. The aluminum alloy of the heat sink maximizes thermal conductivity and improves the overall thermal efficiency of the system, extending the lifespan of the electronic components.
The ESX Quantum Q201A subwoofer has been specifically designed for small cars, sports coupes, and convertibles, but it also fits into other vehicle types due to its compact dimensions of 210 x 73 x 290 mm. These dimensions allow for flexible placement either under or behind the seats as well as in the trunk, depending on the available storage space in your vehicle. Although the device is ideally suited for smaller interiors, the universal design allows for use in vehicles of various categories. If space is limited, this subwoofer is an extremely space-saving solution.
When setting up the Quantum Q201A subwoofer, it is advisable to first set the LPF control to a medium frequency, for example at 100 Hz. The bass boost can be manually adjusted to your preferences; start with a moderate increase of about 6 dB to get a feel for the intensity. The phase setting at 0° is usually suitable for the initial position, especially when the subwoofer and the main speakers are radiating in the same direction. These settings provide a balanced sound and can be further refined at any time according to personal listening taste.
The bass level of the Quantum Q201A from ESX is precisely controlled by the variable LPF and the bass boost. With a setting of 45 Hz and a maximum bass boost of 12 dB, the subwoofer remarkably enhances the lower frequencies. At higher LPF settings between 100 and 150 Hz, the bass becomes flatter to achieve a balanced distribution across the audible frequency range. The bass level remote control allows you to make these adjustments in real-time, so the output can be quickly and easily optimized depending on the genre being played.
The installation of the Quantum Q201A requires careful steps to achieve the best sound result. Start by selecting a suitable installation location that meets the specific dimensions of 210 x 73 x 290 mm. Then connect the subwoofer to the audio system using the high-level or RCA inputs. The power supply is provided via the included cables, and correct polarity must be observed. Use the automatic power-on function to avoid unwanted power consumption. Proper grounding ensures device safety and minimizes the risk of interference noise.
For compact vehicles, the Quantum Q201A offers an ideal solution with its dimensions, as it can be easily integrated into the limited space of such vehicles. The compact design with 210 x 73 x 290 mm allows for flexible installation under or behind the seats. The special tuning for smaller interiors and the balanced power of 100/200 watts RMS/Max ensure excellent bass reproduction. Since the subwoofer is optimally designed to provide excellent performance even at lower volumes, no corner goes unused, even in limited space.

Technical performance of the integrated Class A/B amplifier from ESX

The Class A/B amplifier in the Quantum Q201A not only delivers 100/200 watts RMS/max power, but also impresses with its efficiency. This amplifier's topology combines the advantages of Class A and Class B to ensure balanced sound with minimal distortion. This makes the amplifier ideal for use in vehicles that require crisp and powerful bass reproduction. Higher power could increase current consumption and cause thermal management problems.

LPF of 50-150 Hz and bass boost for optimally tuned sound

With a variable low-pass filter (LPF) between 50-150 Hz, the Quantum Q201A offers you the ability to individually adjust the frequency bandwidth. This is crucial for those seeking a homogenous soundstage with a seamless transition between the subwoofer and full-range speakers. The bass boost of 0-12 dB at 45 Hz gives your system the necessary kick for any music genre. A lower adjustable frequency may be necessary in certain installations to achieve the best tonal balance.

Cast aluminum heat sink and its importance for performance

The ESX Quantum Q201A's cast aluminum heatsink is essential for the system's longevity and reliability. This efficient heat exchanger quickly adapts to temperature changes and protects the amplifier from overheating. This feature is especially valuable during continuous operation under high load. Poor cooling could lead to performance throttling and possible component failure.

Connection options: Line-level and RCA inputs for versatile integration

The ESX Quantum Q201A offers both line-level and RCA inputs, allowing flexible installation in a variety of vehicles. These connection options allow for combination with both factory-installed head units and modern aftermarket radios. Compatibility with line-level inputs is a great advantage when there is no preamp output, while RCA inputs provide clear signal transmission.

Dimensions of the Quantum Q201A and flexible installation options

With compact dimensions of 210 x 73 x 290 mm, the subwoofer can be optimally integrated into a variety of vehicle types. Whether under the seat or in the trunk, this subwoofer fits into virtually any installation environment. A larger subwoofer might have created space problems, especially in small and sporty vehicles.
