STEG BZW80L/R subwoofers for Mercedes-Benz
Mercedes-Benz as a brand is certainly synonymous with quality and German precision. As for the audio systems, it's like any other car - not much emphasis is placed on it. If you don't have an S-Class with the additional Burmester 3D audio equipment for 169 thousand crowns, you will not fully enjoy the sound in the Mercedes. However, the STEG brand offers hope for improvement to owners of C, E, S, GLC, GLE or GLS cars. It is the only one in the world with a comprehensive upgrade program! As can be seen from the philosophy of the STEG brand, all products are based on several years of testing and selection of the best materials. It is no different with these loudspeakers for Mercedes-Benz cars, in which all these many years of development are reflected.
How STEG subwoofers for Mercedes-Benz are mounted
You don't have to modify, cut or otherwise adapt anything in the car, connect amplifiers to the original system in any complicated way or disturb the electronics. Entire sets of speakers are precisely adapted to the replacement of original speakers, using a plug and play system. It couldn't be simpler! The speakers are more sensitive, have higher performance and, thanks to high-quality materials, also a completely different sound. Therefore, there is a huge difference even when connected to the original system. The intention of the Italian developers was to bring you the experience of a live concert in your car, and they succeeded 100% with these speakers!
The subwoofer set includes:
- 2 x 200mm precision-shaped under-dash subwoofers, left and right.
- Complete assembly material for installation.
If the car does not have a Burmester audio system, we recommend connecting an amplifier to the subwoofers to achieve maximum potential. For simple installation in small spaces, we recommend the STEG K2.01 amplifier. (In the original audio system, there is only one 16 cm subwoofer, and instead of the second one there is a blank).

| RMS powerThe RMS power of the subwoofer is the constant power of continuous use of the subwoofer. If the power is exceeded for a longer period of time, irreversible damage may occur, or to burn out the voice coil of the subwoofer. | 200 W |
| Sensitivity (SPL 1W/1m)Subwoofer sensitivity or efficiency. The sensitivity of the subwoofer is given in decibels (dB) and, in simple terms, means that the higher the value, the lower the demands on the power of the amplifier. This is a de facto rating of how a subwoofer converts watts to sound. Sensitivity ratings are in noise level measured at 1 meter from the subwoofer using 1 W (watt of power) or using 2.83 volts at the source at 1 meter. A higher decibel level means the subwoofer is louder with less power. For every 3 dB increase in sensitivity, the subwoofer requires half the power to reproduce the same volume. For example, if an 88 dB subwoofer needs 300 watts to produce a certain volume, then a 91 dB subwoofer needs only 150 watts to reach the same efficiency. | 90dB |
| ImpedanceImpedance - measurement of electrical resistance. When buying a subwoofer, it is very important that everyone make sure that the impedance matches the amplifier that you are connecting to it. For subwoofers with a double voice coil, we recommend following the information in the advice center! Example: A 2 Ohm subwoofer cannot be connected to an amplifier that is only stable up to 4 Ohms. A 4 Ohm subwoofer can easily be used on an amplifier that is stable up to 2 Ohms. Connecting a 4 Ohm subwoofer to an amplifier that is stable up to 4 Ohms also without problems. The most common subwoofer impedance is 4 Ohm. | 2.2 Ω |
| Frequency rangeThe ability of the subwoofer to play a signal from the lowest frequency to the highest, or the ability of a subwoofer to faithfully reproduce sound in a specific frequency band. Subwoofers ideally play from 20 - 150 Hz. Professionally: In the frequency range from 40 to 16,000 Hz, the vast majority of fundamental and overtones (harmonics) of all musical instruments are found. We are interested in the course of the radiated sound pressure in this range of frequencies when the loudspeaker system is supplied with constant power. We call this course the frequency characteristic, which tells us the level of radiated sound pressure in decibels (dB) depending on the frequency. The frequency characteristic of a speaker or speaker system can be expressed most succinctly with a graph. Mostly, however, the frequency characteristic is indicated by indicating the maximum tolerance of the sound pressure in the given frequency range, e.g. 50 to 15,000 Hz -+ 6 dB. Since the frequency characteristics of loudspeakers and systems in general are quite uneven, some manufacturers do not even indicate this maximum tolerance of sound pressure in decibels in their catalogs for tactical reasons. Data impoverished in this way is unfortunately worthless. What is valid is that the manufacturer offers a speaker system with a frequency range of 30 to 20,000 Hz, if he is worried about stating the maximum unevenness of the sound pressure in this range, because he can have a tolerance of, for example, +- 20 dB. The unevenness or undulation of the frequency curve in good speaker systems for high-quality music performance should not exceed +-3 dB in the 80 to 12,000 Hz band and +-6 dB in the 40 to 16,000 Hz band. Greater unevenness already depletes or emphasizes certain tonal areas, which can cause audible or even disturbing distortion. The proportion between fundamental tones and higher harmonics also changes, thereby changing the color of the sound, and individual musical instruments as well as the entire musical image sound unnatural. | 55 - 1500 Hz |
| Subwoofer diameterThe diameter of the subwoofer is indicated on the screw holes. The overall outer diameter of the subwoofer is usually 1-2 cm wider, depending on the size category of the subwoofer. For a 30 cm subwoofer, the outer diameter incl. protective rubber 31.8 cm and in the 25 cm subwoofer it is 26.5 cm incl. protective rubbers. | 200mm (8") |
| Subwoofer mounting depthThe mounting depth of the subwoofer is measured from the bottom edge of the magnet to the bottom edge of the subwoofer's metal or cast basket. | 72 mm |
| QesElectrical Q-factor of driver is the electrical quality factor (electrical damping). If the subwoofer coil moves in a magnetic field, it generates its own current that counteracts its movement. Qes is a dimensionless parameter and the lower the number, the higher the generated current and the more damped the coil movement, thus reducing the total current flowing through the coil, the deflection and the sensitivity around the fs resonance. It varies in values from 0.08 to 0.6, in the extremes, for ordinary universal converters, even 20. Subwoofers with too low a Qes value, a very damped system, are not suitable for certain types of enclosures. | 0.55 |
| QmsMechanical Q-factor of driver is a mechanical factor of quality (mechanical damping). These are mechanical losses affecting (damping) the movement of the subwoofer membrane. Qms is a dimensionless parameter and the higher the number, the smaller the losses, i.e. the deviation and sensitivity in the lower band is also higher, it ranges around 0.4 - 25. | 3.78 |
| QtsTotal Q-factor of driver is a total quality factor, it includes both parameters Qes and Qms (electrical Qes and mechanical Qms). It varies in values from approx. 0.08 to 0.6, exceptionally up to 3. The Qts of the subwoofer is calculated in the same way as, for example, a pair of parallel resistors, so the result is decisively influenced by a smaller value that cannot be exceeded, which is usually Qes. | 0.48 |
| Subwoofer diaphragm materialThe specific material from which the subwoofer membrane is made. | Special paper |
| MassSubwoofer weight in kilograms. The weight is usually given net, i.e. without packaging. | 1.72 kg |
| Other | For Mercedes C, E, S and GLC cars |
