The DD Audio VO-CT45 offers a power capacity with an RMS power of 75 watts and a peak power of 225 watts. These power specifications allow the tweeter to achieve impressive volumes with high precision and minimal distortion. By using a neodymium motor structure and a titanium diaphragm, the tweeter can ensure clear and detailed audio reproduction even at maximum power. This high output power makes the VO-CT45 ideal for use in demanding audio environments where volume stability and sound clarity are essential.
Neodymium in the motor structure of the VO-CT45 has a significant impact on its performance and efficiency. Neodymium is known for its strong magnetic flux density, which can convert electrical energy into mechanical vibrations extremely well despite its low weight and small size. The result is a tweeter that delivers powerful and clear sound while remaining small and lightweight. This allows the VO-CT45 to achieve precise and accurate sound reproduction even under high load. This material is crucial for high performance in a compact space and facilitates the handy design of the product.
The frequency response of 1.2kHz to 20kHz of the VO-CT45 covers the range in which most highs are perceived. This means that the tweeter is capable of efficiently reproducing both mid and extremely high tones. Such a frequency response ensures that every detail of the music, from subtle cymbal hits to emphasized vocal passages, is reproduced fully and accurately. This bandwidth is particularly important for listeners who expect the highest clarity in playback and want to experience the nuances of complex musical arrangements without losing important details.
The universal 1-3/8-inch thread of the VO-CT45 allows for flexible mounting options and integration into both standard and custom audio systems. It enables the use of various horn flares, allowing for customization of sound direction and dispersion. This standard thread size makes it easy to connect the tweeter to existing audio components or integrate it into newly designed systems. The VO-CT45 can thus be easily installed in both professional and hobby audio installations. This versatile connection option ensures a secure and stable attachment that does not shift even under vibrations.
The voice coil diameter of 1.75 inches in the VO-CT45 is crucial for its performance and sound quality. A larger voice coil can absorb and distribute more energy, leading to improved heat dissipation and thus a higher load capacity. This characteristic allows the tweeter to operate with minimal distortion even at high volumes. Such a diameter also contributes to the linearity of movement, which enhances the precision of audio output. Therefore, the larger voice coil diameter enables the VO-CT45 to provide both high performance and fidelity in audio playback.

Your advantages with Masori

Buy DD Audio VO-CT45 horn tweeter - Experience efficiency and power online

Experience the powerful VO-CT45 horn tweeter from DD Audio, which reproduces crystal-clear highs with unprecedented efficiency. Equipped with a replaceable titanium cone and a neodymium motor structure, this tweeter delivers an impressive 75 watts RMS and a peak power of 225 watts. The compact design allows for effortless integration into any sound system without sacrificing performance. With a universal 1-3/8 thread, installation is flexible and easy. Take your music playback to the next level with this powerful solution and benefit from the Masori Lowest Price Guarantee.

Technical performance of the replaceable titanium membrane in the horn tweeter

The replaceable titanium diaphragm in the DD Audio VO-CT45 is a true powerhouse. Titanium is known for its strength and lightness, resulting in superior sound velocity and low distortion. This allows the tweeter to deliver clear and accurate sound even at high levels. A robust titanium diaphragm has the advantage of being extremely resistant to mechanical stress. Should replacement be necessary in the rare event, the simple design makes the installation process straightforward. A higher diaphragm thickness could further increase stability, but at the expense of lightness and thus rapid vibrations.

Neodymium motor structure of the VO-CT45: Maximum efficiency in detail

The neodymium motor structure of the DD Audio VO-CT45 is a prime example of high efficiency. As one of the strongest magnets available, neodymium allows for a compact design while still delivering a high magnetic flux density. This results in precise control of the diaphragm movement, making music reproduction rich and dynamic. A lower magnet value would reduce efficiency and lead to blurred sound peaks. The combination of a lightweight design and a strong magnet optimizes the size-to-power ratio, which is crucial for mobile use in vehicles.

The compact design and the universal 1-3/8″ thread of the tweeter

The universal 1-3/8 thread in the VO-CT45 ensures seamless integration into various enclosure shapes, allowing adaptation to individual application needs in the car hi-fi sector. These features open up a wide range of application possibilities and offer flexibility in system configuration. With a 114 mm diameter and 52.8 mm mounting depth, this tweeter is compact and lightweight, making installation easier. A driver diameter that is too large could compromise compatibility with smaller enclosures, while a smaller diameter would reduce the air volume required, but at the expense of performance.

Frequent bandwidth of the DD Audio VO-CT45: 1.2 kHz to 20 kHz

The frequency response of the DD Audio VO-CT45 ranges from 1.2 kHz to 20 kHz. This bandwidth covers the entire range, which is crucial for high-frequency clarity in the audio domain. This ensures a vibrant and detailed soundscape. A lower minimum kHz value would allow the tweeter to reproduce lower frequencies, but this would compromise high-frequency performance. A wider frequency response signals greater system versatility, which is considered advantageous in the car hi-fi market.

RMS power of 75 watts and peak power of 225 watts

The DD Audio VO-CT45 horn tweeter offers a continuous power consumption of 75 watts RMS and can handle peaks of up to 225 watts. These values ​​indicate the ability to remain powerful even at high levels without generating distortion. A higher RMS value would have allowed for more sustained power handling, but this could significantly increase the design weight. A lower peak power, on the other hand, would be problematic in the uncompromising power range, as fast peaks in dynamic music would be particularly affected.

4 ohm impedance for optimal system compatibility

The 4 ohm impedance of the VO-CT45 is a common standard, ensuring compatibility with most car hi-fi systems. Matching common amplifier impedances maintains efficient power flow, ensuring distortion-free performance and sound clarity. A lower impedance could increase power consumption and require more amplification, while a higher impedance could reduce system volume. Choosing this impedance level ensures a good balance between power and efficiency.

Efficiency of the DD Audio VO-CT45 of 106 dBSPL

With an efficiency of 106 dBSPL, the DD Audio VO-CT45 horn tweeter is ideal for extracting maximum volume from a small input. This value indicates high efficiency, which is particularly advantageous for small amplifiers or limited power resources. A higher efficiency would enable extreme volumes even with minimal amplification, while a lower efficiency would mean more power would be required to achieve the same volume.

Installation depth of 52.8mm - Simple and space-saving

The DD Audio VO-CT45 features a remarkably shallow 52.8 mm mounting depth, allowing for space-saving installation. This dimension is particularly advantageous in vehicles with limited installation space, as it allows for installation even in confined spaces without compromising performance. A reduced mounting depth could facilitate installation in extremely tight spaces, but at the expense of internal driver stability.
