The Masterstroke SS-652C speaker set from Steg covers an impressive frequency range of 40 to 20,000 Hz, encompassing nearly the entire audible spectrum. The STEG SS-26 full-range driver offers a frequency range of 145 to 20,000 Hz and does not require a separate tweeter for high frequencies. The STEG SS-65 mid-bass driver operates from 40 to 1,500 Hz. The comprehensive coverage ensures that all sounds, from deep bass to high treble, are reproduced clearly and precisely. Both components use neodymium magnets to create a strong, uniform magnetic field for precise diaphragm movements, which is crucial for clear sound.
The membranes of the Masterstroke SS-652C have been developed with specific technological approaches to ensure high sound quality. The system's full-range driver uses a ceramic SW membrane, which allows for a quick response to frequency changes due to its lightness and stiffness, minimizing distortion. The mid-woofer, on the other hand, is equipped with a polypropylene membrane, known for its water resistance and durability. This choice of material optimizes sound fidelity and ensures that even at high volumes, precise and distortion-free sound reproduction is maintained, which is crucial for an immersive listening experience.
The Thiele/Small parameters of the Masterstroke SS-652C provide important insights into the acoustic behavior of the speakers. For example, the STEG SS-26 full-range drivers have an equivalent volume VAS of 0.26L, a Qts value of 0.49, and a Qms value of 1.1, indicating a high mechanical quality of the system. Simply put, these parameters influence the resonance frequency and the oscillation behavior, optimized for precise sound reproduction. The STEG SS-65 mid-bass driver features a VAS of 9.71L and a Qts of 0.36, characterized by a larger excursion. Such detailed parameters make the speaker set unique and particularly interesting for audio experts.
The installation of the Masterstroke SS-652C speakers from Steg in vehicles is relatively simple due to the thoughtful design. The mid-bass driver, the STEG SS-65, has an outer diameter (OD) of 178mm and a mounting depth (MD) of 64mm. The full-range speaker SS-26, with an OD of 84mm and MD of 40mm, is suitable for the standard installation location without major modifications. Also important are the bolt circle diameters (BCD) of 6x166mm for the mid-bass driver and 4x77mm for the full-range speaker. This offers flexibility in mounting, provided that the enclosures can accommodate the specific dimensions.
A central feature of the Masterstroke SS-652C speaker set from Steg is the use of neodymium magnets. Neodymium is one of the strongest magnetic materials available and offers significant advantages in terms of performance and efficiency. This strong magnet provides a powerful magnetic field with minimal volume, allowing the speaker to remain compact without being burdened by excessive weight. The use of neodymium not only improves sound precision but also reduces distortion, even at higher volumes. This is crucial for a rich and realistic sound image.
The Masterstroke SS-652C is characterized by its performance parameters that contribute to an exceptional sound quality. It consists of two main components: the STEG SS-26 full-range speaker with a nominal power handling of 30W RMS and the STEG SS-65 mid-bass driver, which can handle 60W RMS. Both units have an impedance of 4 Ohms, making them ideally suited for integration into various audio systems and amplifiers. The combination of high power handling and the responsiveness of the system contributes to a clear and strong sound reproduction that remains undistorted even at higher volume levels.
The diameter of the voice coil plays an important role in the performance of the Masterstroke SS-652C speaker. The STEG SS-26 full-range speaker has a voice coil with a diameter of 20.4mm, while the STEG SS-65 features a voice coil with an impressive 55.8mm. A larger diameter allows for higher load capacity and improved heat dissipation, which is particularly crucial at higher volume levels. The larger voice coil of the mid-bass driver provides more control and precision in diaphragm movement, resulting in improved detail depth and clarity that even the most demanding audio enthusiasts will appreciate.
The impressive sound of the Masterstroke SS-652C is created by a variety of technical details. The wide coverage of the frequency spectrum by the full-range driver reduces the need for separate elements like tweeters, minimizes distortion, and promotes a uniform sound image. The tailored use of materials such as the ceramic SW diaphragm for the full-range driver and the PP diaphragm for the mid-bass driver enhances the quick response of the components to sound changes. Supported by powerful neodymium magnets, these features contribute to the creation of an impressively realistic and spatial soundstage, thus producing a special acoustic experience.
To ensure a smooth transition to the Masterstroke SS-652C from Steg, some checks must be performed at the installation site. The dimensions are crucial: The mid-bass driver requires an installation space with an outer diameter (AD) of 178mm and a mounting depth (ET) of 64mm, while the full-range driver needs an 84mm AD and 40mm ET. Furthermore, the existing speakers may need to be adjusted to the hole circle diameters of 6x166mm and 4x77mm at worst. If an existing car audio system is being replaced, the connections usually also need to match the 4-ohm impedance. Considering these technical requirements avoids complications and ensures that the sound is optimally showcased.
In the Masterstroke SS-652C System, there are significant differences in sensitivity, achieved through material selection and specific design features. The STEG SS-65 mid-woofer has a high sensitivity due to its neodymium magnets and PP diaphragm, ensuring efficient conversion of input power into sound pressure, but it requires operation under load without the impression of distortion. In contrast, the STEG SS-26 full-range speaker covers a broader frequency spectrum, maximizing sensitivity in the higher frequency ranges; this positively affects clarity and detail in high-resolution audio sources.
