The Masterstroke MSS6 from Steg is a 6.5" mid-bass speaker, characterized by its carbon fiber diaphragm and aluminum die-cast basket. With a power of 200W, it offers impressive sound quality. The drilled pole core, in combination with a powerful neodymium magnet, enhances the acoustic performance of the speaker. The impedance is 4 ohms, contributing to efficient sound conversion. The frequency range extends from fs=68Hz to VAS=14.5L. Additionally, the dimensions for installation are clearly defined with an outer diameter of 168mm, a cut-out diameter of 141mm, and a mounting depth of 62.3mm.
A carbon fiber membrane like that of the Masterstroke MSS6 from Steg ensures improved sound quality, as it is lightweight yet rigid, minimizing distortion. These material properties allow the speaker to reproduce sound with high precision and clarity. Especially in terms of detail accuracy and micro-dynamics, the carbon fiber membrane showcases its strengths. The combination of lightness and strength helps to present fast transients cleanly and with low distortion. This is ideal for audiophiles who value fidelity in music playback.
The aluminum die-cast basket of the Masterstroke MSS6 from Steg offers significant structural advantages for the speaker. An aluminum die-cast basket is particularly robust and provides the necessary stability for the speaker to minimize resonances. This aspect is crucial, especially when installed in vehicles where vibration loads are high. The aluminum die-cast also helps to efficiently dissipate heat, which is essential for a powerful speaker with 200W power to protect the speaker in the long term and ensure a consistently high-quality sound experience.
In the STEG Masterstroke MSS6, the frequency range plays a crucial role in sound reproduction. The speaker is optimized for a frequency response starting from fs=68Hz. This value indicates how low the speaker can sound before the performance decreases. Additionally, the speaker has a VAS value of 14.5L, which describes the effective volume of the resonance cavity. The tuning with a Qts of 0.81 explains the balance between bass extension and efficiency. These parameters ensure that the speaker delivers a balanced sound across a wide frequency spectrum.
For the installation of the Masterstroke MSS6 from Steg, several dimensions are crucial. The outer diameter is 168mm, while the installation diameter measures 141mm. The installation depth is specified as 62.3mm, which must be taken into account when selecting the appropriate installation location. The LK, or bolt circle diameter, is 6 x 158mm. Especially if you want to integrate the speaker into an existing audio system, these measurements are essential to ensure correct placement and corresponding acoustic properties.
The drilled pole core in the Masterstroke MSS6 from Steg has technical advantages that particularly improve cooling properties. A drilled pole core allows for better ventilation of the coil and magnet, which reduces thermal stress. This is especially important under high power demands, such as those produced by the 200W speaker. The reduced heat generation not only extends the lifespan of the speaker but also optimizes the efficiency of sound reproduction. For listening situations with a heavy load, this technical aspect is crucial.
The use of a neodymium magnet in the Masterstroke MSS6 by Steg plays a crucial role in the speaker design. Neodymium magnets are particularly strong and compact, allowing for a compact speaker design without compromising sound quality. This magnet technology provides a high magnetic flux density, making the movements of the diaphragm more precise and thus increasing sound fidelity. The compact design is also ideal in applications where space optimization is critical, such as in vehicles or other tight installation locations.
The 4-ohm resistance of the Masterstroke MSS6 by Steg significantly contributes to the efficiency of sound conversion. A speaker with such impedance offers the possibility of receiving sufficient power from many common amplifiers, enabling intensified volume and improved audio playback. Since the amplifier requires less voltage with a 4-ohm speaker, it can respond to audio signals more quickly and precisely. This resistance value is ideal for integration into systems with standard amplifiers and prevents energy losses that could impair sound quality.
The SD value, that is, the effective diaphragm area, of the Masterstroke MSS6 is 138.9 cm². This specification is crucial for calculating the sound pressure potential of the speaker. A larger diaphragm area can move more air at the same diaphragm displacement, resulting in louder and more powerful bass. The SD value directly influences the efficiency and effectiveness of the bass range. Especially for use in high-performance audio systems that require impressive bass, this parameter represents a significant advantage.
The Qts value of the Masterstroke MSS6 is specified as 0.81 and plays a significant role in the sound characteristics of the speaker. Qts determines the overall quality of the driver and influences how much the speaker diaphragm vibrates and thus reproduces frequencies. A Qts value of 0.81 indicates moderate damping, which means that the speaker can be used in both compact and vented enclosures. This level of flexibility allows for adaptation to various installation conditions and listening environments, providing a lot of freedom in designing an audio system.
