The sound accuracy of the BMX45C from STEG is achieved through the precise tuning of components and materials. Midrange drivers with pressed paper membranes ensure a natural midrange reproduction, utilizing optimized magnetic fields through the use of a neodymium magnet. The specific Q factors (Qms 2.34, Qes 0.30, Qts 0.26) contribute to a controlled resonance. The titanium silk dome tweeter provides a brilliant finish to the highs. These characteristics combine to maximize acoustic precision and deliver sound fidelity that is a true delight for discerning listeners, both technically and musically.
The BMX45C speaker set from STEG features precisely specified dimensions that ensure easy installation. The installation diameter of the midrange speakers is 98 mm, and the installation depth is only 36 mm. These dimensions are optimal for integration into BMW models and provide a perfect fit in the designated speaker cutouts. The entire package, including tweeters and crossovers, is designed to adapt the installation dimensions ideally to the geometric conditions of the vehicles, saving space and ensuring a harmonious installation.
The speakers of the BMX45C from STEG use selected materials to optimize sound quality. The midrange driver features a water-repellent paper diaphragm that combines natural sound with high resistance to moisture. The neodymium magnet plays a crucial role in producing powerful and precise sound images. The tweeter is made of titanium silk and ensures clear mid to high frequencies that expand the acoustic stage. These innovative material combinations guarantee outstanding performance that significantly enhances the sound profile in the vehicle.
The BMX45C speaker set from STEG has an impedance of 4 Ohms and is designed for a maximum power consumption of 30 W. These values are specifically tailored to the requirements of BMW vehicles and offer excellent integration into the existing vehicle architecture.

Your advantages with Masori

Experience a three-dimensional soundstage with the Steg BMX45C high-performance speaker set for BMW

If you're looking for a high-quality sound experience, the Steg BMX45C is the right choice for you. Here you can buy this speaker set for your BMW online at an affordable price. The set offers an impressive three-dimensional soundstage and unsurpassed sonic accuracy. With the water-resistant paper cone midrange drivers and optimized titanium silk dome tweeters, the acoustics in your cabin are significantly enhanced. Thanks to Masori's lowest price guarantee, you always get your audio product at the best price. The set also includes an easy-to-install plug-and-play cable set and crossover networks for immediate use.

Technical performance of the Steg 2-way speaker set for BMW

The Steg BMX45C speaker set offers impressive technical specifications for the discerning BMW driver. The midrange driver's resonance frequency is 75 Hz, and its water-resistant paper cone ensures a natural sound. This demonstrates excellent adaptability for vibration-free use in the vehicle. The 4-ohm impedance ensures efficient power delivery and optimizes output power while minimizing power losses. A higher ohm value could increase the power handling but would compromise the system's efficiency.

World-class frequency response: From 90 Hz to 15,000 Hz

The BMX45C system offers a frequency response of 90 Hz to 15,000 Hz, an impressive range for a speaker system of this size. This frequency range allows the midrange drivers to cover rich and deep bass tones all the way to clear highs, opening up a comprehensive sound spectrum for first-class music productions. Extending the frequency response further could further enhance the sound's completeness, but at the expense of the specific focus on frequencies optimized for the vehicle's audiovisual needs.

Efficiency of 88dB: Volume without compromise

An efficiency of 88 dB means the speakers can produce high volumes with low power. This value is ideal for car audio systems, which often have to operate with limited amplifier output. The high sensitivity allows even the smallest sound details to be extracted, resulting in a detailed sound experience. A higher efficiency could, in principle, enable an even more powerful performance, but at the expense of fine-tuning and detail resolution.

Use of neodymium magnets for improved magnetic field

The Steg BMX45C's midrange driver utilizes neodymium magnets to create a strong magnetic field in a compact size. This ensures efficient diaphragm movement, resulting in a more dynamic and clear sound. Neodymium magnets support more precise audio reproduction by optimizing linearity of movement, making this magnet type particularly suitable for high-performance automotive speakers. A weaker magnet could limit dynamic range and result in muddy bass.

Thiele-Small parameters and their impact

The Thiele-Small parameters play a critical role in the design of the Steg BMX45C loudspeaker set. With a mechanical Q factor, Qms, of 2.34, good bass extension is achieved with accurate performance under all conditions. The preload ratio, Qts, is 0.26 and combines the best aspects of electrical and mechanical damping behavior into the system. These parameters indicate that the loudspeaker is designed for sealed cabinets, resulting in controlled, clean bass reproduction. A higher Qts value could provide more flexibility for different cabinet types, but precision might suffer.

Lightweight construction: Focus on safety and efficiency

Weighing just 0.38 kg per midrange driver, the speaker set remains lightweight, making it easy to handle and offers flexible installation positions within the car. The compact mounting depth of 36.0 mm allows for installation without significant modifications to the vehicle's original enclosure. Lighter components also promote energy efficiency, but they may cause the sound to become somewhat unstable under extreme loads.

Plug&Play cable set and crossovers included

Another highlight of the Steg BMX45C is the plug-and-play cable set in conjunction with the crossovers included in the set. These ensure quick and easy installation and allow for worry-free configuration thanks to simple, closed circuits. A correctly aligned crossover contributes to a clean reproduction of all sounds through precise separation across the frequency range and prevents distortion in the highs. Poorly calibrated crossovers can lead to sonic deficiencies in the transition between speakers.
