Active subwoofer Blaupunkt GTw 190 A - 24V
The Blaupunkt GTw 190 A is a slim active car subwoofer designed to improve the bass component of your car radio or audio system even when installation space is limited. Thanks to its compact under-seat design it is easy to mount under a seat and does not take up trunk space, making it ideal for daily use as well as long journeys. The subwoofer features an integrated amplifier with 80 W RMS and up to 150 W peak power, delivering strong, deep and precise bass without the need for an external amplifier. A compact controller mounted on the cable allows convenient adjustment of level, frequency range and phase directly from the driver’s seat so you can tune the bass exactly to your taste.
The subwoofer has a 5″×8″ (approx. 13×20 cm) driver with 2 Ω impedance, up to 95 dB sensitivity and a frequency range of 30 to 150 Hz, providing deep bass without overloading the other speakers. Its low height and compact dimensions (approx. 280×200×70 mm) make it suitable for installation even in smaller vehicles where there is no space for a conventional subwoofer. The Blaupunkt GTW 190 A is an ideal choice for drivers who want to significantly improve the bass performance of their car audio system without complicated interior modifications, offering quality sound, easy installation and practical control.

| 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. | 30 - 150 Hz |
| Low-pass filter (LPF) | Yes |
| 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 |
| Bass boost functionBass boost or bass enhancement. With this function, the bass itself can be emphasized, at a high level of bass boost, the speakers and the subwoofer can distort a lot and the sound will be worse than better. We therefore recommend using the "bass boost" function wisely. | No |
| 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. | No |
| 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 | 280 x 200 x 70 mm |
| Mass | 4.4 kg |
