HIGH-QUALITY SOUND IN YOUR CAR

The NEOLINE ULTERA RS52 combines two speakers in one system – a tweeter and a midbass speaker. This design allows different frequency ranges to be reproduced efficiently, creating a balanced and coherent sound stage.

The coaxial construction helps maintain a well-balanced relationship between high and lower frequencies, delivering clear, natural, and detailed sound. The compact design also makes the speakers easy to integrate into a car audio system.

2-WAY COAXIAL DESIGN

The RS52 are 2-way coaxial car speakers, with the tweeter and midbass speaker positioned along the same axis.

This design allows different frequency ranges to be reproduced from a single compact speaker. It is a practical solution for car audio systems where good sound quality, easy installation, and limited mounting space are important considerations.

5.25-INCH SIZE FOR EASY INSTALLATION

The 5.25-inch (13.3 cm) size is a compact format suitable for installation in various locations inside a vehicle, including car door panels.

Thanks to the coaxial design, there is no need to install a separate tweeter, allowing the system to save space while providing high-quality sound.

Before installation, check the compatible speaker size, mounting depth, and mounting points for your specific vehicle.

DUAL-LAYER FIBERGLASS CONE

The NEOLINE ULTERA RS52 features a dual-layer fiberglass cone designed to combine structural rigidity, low weight, and good acoustic performance.

The fiberglass structure helps the cone respond accurately to changes in the audio signal while reducing unwanted resonance. This allows the speaker to reproduce sound with greater clarity and accuracy, even at higher volume levels.

Fiberglass also offers good resistance to moisture and temperature fluctuations, making it suitable for use in the automotive environment.

POWERFUL AND PRECISE LOW-FREQUENCY REPRODUCTION

The fiberglass cone and optimized construction help reproduce richer and more dynamic lower frequencies.

The speaker maintains stable performance even under higher loads, keeping music clear and controlled. The design allows lower frequencies to be reproduced with good depth while maintaining overall sound balance.

SILK DOME TWEETER

The RS52 features a silk dome tweeter designed to provide smooth and natural high-frequency reproduction.

The silk diaphragm helps reduce unwanted distortion and reproduce vocals, instruments, and fine musical details clearly and naturally. High frequencies remain detailed without sounding overly sharp.

BUTYL RUBBER SURROUND

The speaker surround is made from butyl rubber, offering flexibility and resistance to temperature fluctuations.

The flexible surround allows the cone to move smoothly and respond accurately to the audio signal. Its durable construction also contributes to long-term performance in the automotive environment.

STABLE PERFORMANCE IN DIFFERENT CONDITIONS

The RS52 is designed for use across a wide temperature range of –20°C to +60°C.

The butyl rubber surround maintains the required flexibility at lower temperatures, while the speaker materials provide stable performance under higher loads.

This is particularly important for a car audio system that is exposed to changes in temperature, moisture, and other environmental conditions.

ACOUSTIC LABYRINTH IN THE REAR STRUCTURE

The specially designed rear structure helps control rear sound waves and optimize acoustic performance.

This design helps to:

• Improve low-frequency reproduction.
• Reduce the impact of unwanted rear sound waves.
• Provide more stable speaker performance.
• Make more effective use of the compact speaker design.

POWER AND SENSITIVITY

With a maximum power of 120 W per speaker, the RS52 can deliver dynamic and powerful sound even at higher volume levels. Since the set includes two speakers, the total maximum power of the system is 240 W.

With 89 dB sensitivity, the speakers can efficiently reproduce sound even when connected to a standard factory car audio system. An additional amplifier is not required for clear and sufficiently loud playback, although an amplifier can be useful for maximizing the system’s power potential.

NEOLINE ULTERA RS52 – A PRACTICAL CAR AUDIO UPGRADE

If you are looking for 5.25-inch car speakers that combine a compact size, easy integration, and high-quality sound, the NEOLINE ULTERA RS52 is a practical choice.

The 2-way coaxial design, fiberglass cone, silk dome tweeter, and butyl rubber surround create a balanced speaker system designed to deliver clear, detailed, and dynamic sound inside your vehicle.
