Active subwoofer Eton RES 12
A powerful universal subwoofer for everyone who wants more bass in their car - without much effort and without wasting space. The ETON RES 12 flat active subwoofer can be hidden and space-savingly installed in the space for the spare wheel or even in the spare wheel (from 15" rim). Thanks to the Plug & Play connection system, the bass box is easy to install and remove, which is why it is also ideal for leasing vehicles. Small, practical, powerful! The powerful active subwoofer for the spare wheel comes in a high-quality and strong aluminum die-cast housing. The 30 cm/12" woofer with a durable voice coil with an impedance of 2 ohms is driven by an integrated amplifier with a power of 500 W. The result - clean performance and rich, expressive deep bass! The active woofer is made in Germany and is equipped with an integrated low-pass filter of 50-120 Hz and a cinch input (low-level input). For connection to factory radios without a REM output, the RES 12 has a high-level input with an auto-on function. All controls are located on the included wired remote control. Active operation without remote control (control via DSP/head unit) is possible using a connecting plug.

| RMS power of the subwooferThe RMS power of an active subwoofer is the constant power that the active subwoofer can play over a long period of time. We recommend following this value. The RMS power of active subwoofers is taken as the RMS power of the integrated amplifier, which in most cases is slightly undersized, which guarantees protection against subwoofer burning. | 250 W |
| Maximum subwoofer performancePeak performance or Max. power that an active subwoofer can play for a moment (approx. 0.5 s), for example when percussion instruments are struck in a recording. But it is not as important a parameter as the RMS power. | 500 W |
| Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers. | D |
| The diameter of the subwoofer usedThe diameter of the subwoofer that is installed in the active box. | 300mm (12") |
| Frequency rangeThe ability of the device to reproduce a signal from the lowest frequency to the highest, or the ability of an active subwoofer to faithfully reproduce sound in a specific frequency band. 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 specify this maximum tolerance of sound pressure in decibels for reasons of prestige. Data impoverished in this way is 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, i.e. the undulation of the frequency course in good speaker systems for 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. | 50 - 120 Hz |
| High level inputThe high-level input on the active subwoofer enables connection directly to the speakers in the car without purchasing an external high/low converter. Use in the case of mounting an active subwoofer on the original car radio. | Yes |
| Automatic on and offThis function will facilitate your installation and solve the problem of finding a remote signal, which is sometimes a problem with original car radios. The active subwoofer with the Auto sense function can recognize that the equipment in the car is active and turn itself on. A useful and practical feature. | Yes |
| Phase rotation optionPhase shift is a linear electronic oscillator that produces a sinusoidal output. It consists of an inverting part of the amplifier such as a transistor. The feedback network "shifts" the phase at the output of the amplifier by 180 degrees to the oscillation frequency and gives positive feedback. The Phase shift filter produces a phase shift that increases with increasing frequency. This is usually used when the subwoofer sub-assembly is out with the magnet, or when two amplifiers are connected externally. Phase Shift is also used with active speaker wiring, where the time shift of the speakers is set. The point is that the subwoofer does not play the bass late, and for this reason better amplifiers offer this phase reversal option. | Yes |
| Crossover setting optionsUsually this involves tuning the LPF filter on the active subwoofer. | Yes |
| Cabling included in the packageSome active subwoofers have complete wiring included in the package. In the event that the package really includes complete wiring for connection, we mark the parameter as "yes". If the wiring is not included, it must be purchased. | Yes |
| Remote control included in the packageSome models of active subwoofers also have wired remote controls in the package, which on the one hand connect to the active box, and on the other hand you have a potentiometer that you can place anywhere in the cabin. A common place to place the remote control is under the steering wheel. The advantage is the regulation of power, and therefore volume, depending on driving conditions and the mood of the crew in the car. | Yes |
| Protective gridProtective grids or bars, as protection against mechanical damage to the subwoofer. | Yes |
| Active subwoofer dimensions | 341 x 321 x 164 mm |
