Neodymium magnet and high efficiency: key factors of the midrange driver

The midrange driver in STEG's BM45C-II set impresses with its powerful neodymium magnet. This type of magnet, known for its high energy density, enables compact and lightweight designs. This significantly increases the speaker's efficiency. The efficiency of 88 dB at 1W/1m is impressive and ensures powerful reproduction. A higher efficiency would further increase the sound pressure, while a lower value would result in quieter reproduction. Neodymium magnets optimize the ratio between size and sound performance and are in high demand in the audio industry.

Paper membrane for natural sound reproduction

The use of a special paper cone in the BM45C-II midrange driver delivers a natural and unadulterated sound. Paper cones are known for their exceptional sound quality due to their fast response and low mass. They enhance the resonant frequency of 75 Hz, which is ideal for gaming and film applications. A higher value could compromise lower bass frequencies, while a lower value would strengthen the cone. Compared to synthetic alternatives, paper cones offer a pleasantly warm timbre.

Resonance frequency and frequency response of the loudspeaker

The resonance frequency of the bridge midrange driver is optimally selected at 75 Hz. This ensures precise bass and depth of sound. The frequency response of 90 Hz to 15,000 Hz ensures that all important frequencies are covered. In comparison, midrange drivers on the market often only cover frequencies up to about 10,000 Hz. A higher frequency range would further improve the treble reproduction. Even so, this speaker already provides a solid foundation for audiophile sound experiences.

Two-way design: Perfect coverage of the sound range

The two-way system of the BM45C-II speaker set enables detailed sound separation. The 25 mm titanium silk dome tweeter delivers brilliant highs, while the 100 mm midrange driver ideally covers the mid-frequency range. This separation ensures a clear and simultaneously dense sound. A system with more than two ways could provide even more differentiated acoustics, but the offered setup is optimally balanced for its price.

Q-factor and its influence on sound and design

The Qms value of 2.34 and the Qes value of 0.30 result in a Qts of 0.26. These values ​​significantly determine the control of the cone movements and thus influence the sound neutrality. A lower Qts tends to provide tighter bass reproduction, whereas a higher Qts would offer smoother transitions at low frequencies. The compactness of these speakers provides a balanced foundation for wear-free and detailed music reproduction.

Mms and Vas: Perfect balance between mass and air volume

The Mms value of 6.95 grams combined with a Vas value of 4.97 liters reflects the balance between moving mass and air volume control. A high Mms could improve bass reproduction, while a low Mms would increase precision. The Vas value influences the tuning to your vehicle's interior and ensures that the BM45C-II speaker set produces a harmonious sound, regardless of the vehicle's ambient conditions.

Installation and accessories: Plug&Play cable set and crossovers

The BM45C-II speaker set comes with a comprehensive package, including two tweeters, two midrange drivers, and the corresponding crossovers. These are crucial for perfect sound separation. The plug-and-play cable set guarantees effortless installation. On-site installation is also available for the Frankfurt (Oder) location. Installing the speakers requires no special modifications, allowing for convenient and time-efficient installation.

Steg speaker set: DT Mini compatibility and specifications

The BM45C-II speaker set is specifically tuned for BMW and MINI models. These include the BMW F-Series, G-Series, and E-Series (with minimal adjustment), as well as MINI F models such as the MINI F54 to F60. This compatibility ensures perfect integration and brings out the best in every vehicle model. The FAQ & Help section of the masori.de webshop answers all frequently asked questions about installation.

Mounting aspects: depth and diameter of the midrange driver

The midrange driver of STEG's BM45C-II kit has a mounting depth of 36 mm and a diameter of 98 mm, further maximizing compatibility with the aforementioned vehicle models. A greater mounting depth could limit placement within the vehicle, while a smaller diameter could impact bass reproduction. The precise dimensions allow for easy installation without sacrificing space in the vehicle interior.

Sound pressure level and its effects on the listening experience

With a maximum sound pressure level of 88 dB, the BM45C-II guarantees a clean, distortion-free sound. The high sound pressure level ensures clear and powerful reproduction even at higher volumes, which is essential for dynamic music. A higher sound pressure level could lead to clipping, while a lower one provides a quieter listening experience. Typically, a typical range for car speakers is in a similar range. Choosing the BM45C-II speaker set from STEG offers not only economic advantages but also excellent technical support. This includes the comprehensive audio blog for in-depth insights.
