The Accuton C30-4-358 is a tweeter with an ultra-hard 30mm ceramic diaphragm in a 58 mm aluminum housing. It is exclusively designed for use in home hi-fi applications and must not be installed in vehicles under any circumstances. A proprietary tensioning technique allows for easy mounting and adaptation to various front panel designs. Since the break-up frequency of the diaphragm is above the audible range and well damped, no diaphragm cutouts are required. A unique FEA-optimized under-hung design with ventilated titanium voice coil former and dual neodymium magnets ensures low energy storage, excellent heat dissipation, and high excursion for low compression and extremely low distortion with values around 0.07% at 2.83 V and 0.5% max at 110 dB. The newly designed soft fabric surround centers the moving parts with improved linearity.

"We recommend our Accuton C30-4-358 in an application above 1800 Hz."

The Accuton C30-4-358 tweeter features an ultra-hard 30 mm ceramic membrane housed in a 58 mm aluminum enclosure. A unique feature is the proprietary tensioning technique that facilitates mounting and adjustment to various front panel designs. The tweeter offers a membrane break frequency that is above the audible range and is well damped, eliminating the need for membrane cutouts. Additionally, it is driven by an FEA-optimized underhung design combined with a ventilated titanium voice coil former and a dual neodymium magnet, ensuring low energy storage and extremely low distortion.
The Accuton C30-4-358 tweeter offers a power handling of 120 W RMS and an efficiency of 93.5 dB. These specifications are impressive for a tweeter, as they ensure that the speaker is both powerful and efficient. Due to its high sensitivity, the tweeter can produce high volumes even at lower voltages. This combination of performance and efficiency makes the C30-4-358 ideal for demanding audio applications where high audio quality is required without excessively stressing the amplifiers.
The Accuton C30-4-358 has specific Thiele-Small parameters that define its performance characteristics. The free air resonance frequency (Fs) is 826 Hz, while the mechanical quality factor (Qms) is 4.5. The electrical quality factor (Qes) is specified as 0.85, resulting in a total quality factor (Qts) of 0.71. Other important values include the moving mass (Mms) of 0.39 g, the compliance of the diaphragm suspension (Cms) of 0.145 mm/N, and the mechanical resistance (Rms) of 0.97 Kg*S. These parameters are crucial for determining the acoustics and adaptability of the tweeter.
The C30-4-358 tweeter from Accuton uses a 30 mm voice coil in underhung design. The voice coil carrier material is made of titanium, which ensures both lightness and high thermal capacity. The conductor material is copper (Cu), known for its low electrical resistance and high conductivity. The impedance of the voice coil is 4 Ohms, making it compatible with a variety of amplifiers. With an inductance (Le) of only 0.01 mH and a force factor (Bl) of 3.98 N/A, the tweeter offers outstanding dynamics and precision in sound reproduction.
The overall dimensions of the C30-4-358 are determined by its outer diameter of 57.6 mm and a height of 28 mm. The required cutout size is 58 mm, while the front panel thickness must be at least 6 mm. These critical dimensions are essential in planning the installation to ensure the perfect installation and performance of the tweeter. Weighing only 0.3 kg, the C30-4-358 is compact and lightweight, making it ideal for use in a variety of environments.
The proprietary tensioning technique of the Accuton C30-4-358 allows for flexible mounting by seamlessly adapting to various front panel designs. This technique employs special fastening methods that do not require elaborate modifications to the diaphragm, making the overall construction more stable and user-friendly. This adaptability enables the tweeter to be used in various audio applications without compromising sound quality. The tensioning technique also supports high excursion for lower compression and virtually distortion-free audio playback.
The Accuton C30-4-358 tweeter is optimally suited for frequencies above 1800 Hz. Thanks to its ceramic membrane and FEA-optimized design, it offers efficient reproduction in the upper frequency range, with high purity and precision at the forefront. The membrane is also designed so that its break-up frequency is above the audible range and is well damped, ensuring that sound reproduction remains clear even at high volumes. This precise high-frequency range makes the tweeter ideal for applications where excellent clarity and detail fidelity are required.
The Accuton C30-4-358 tweeter is specifically designed for home and studio applications and is not suitable for automotive use. For automotive environments, there is a special automotive version from Accuton that has been developed for use in cars. This version is resistant to typical automotive challenges such as vibrations, weather influences, and extreme temperatures, ensuring optimal audio quality in those conditions. Therefore, those looking for a tweeter for use in vehicles should consider the specially available automotive series to find a suitable solution.
The 30 mm ceramic membrane of the Accuton C30-4-358 has a significant impact on its sound characteristics. Ceramic is known for its rigidity and lightness, which means that the membrane can move quickly without deforming. This property allows for very precise and detailed reproduction of high frequencies. Additionally, the membrane is designed so that its break-up frequency is well above the audible range, which reduces distortion at maximum loads. As a result, you will experience an incomparably clear and clean sound image.
The underhung voice coil design of the Accuton C30-4-358 has dynamic advantages in terms of sound performance. The voice coil remains fully within the magnetic field during linear operation, which ensures consistently high efficiency and lower distortion. The ventilated titanium voice coil carrier also allows for excellent heat dissipation, minimizing thermal compression and promoting the longevity of the tweeter. This architecture improves linearity and provides undistorted sound reproduction at both low and high volumes, without audible distortion.
