Active subwoofer ESX V1100Av2
The ESX V1100Av2 is the second generation of one of the most successful active spare-wheel subwoofers, which has earned an excellent reputation among professionals and customers. Compared to the previous version, it offers more practical controls and several construction improvements while retaining everything that made the original model successful – a powerful 11" subwoofer with a metal cone, a robust aluminum enclosure and an integrated class A/B amplifier. The new generation moves all important controls to the top of the enclosure, where you can easily set the crossover frequency, subsonic filter, Bass Boost and phase. As a result, the wired remote volume control could be significantly reduced and now serves only to conveniently control the bass level from the driver’s seat. A practical new feature is a detachable power connector that allows quick removal of the subwoofer, for example when you need to use the spare wheel well. The heart of the system is an 11" subwoofer with a rigid metal cone and a 64 mm voice coil that easily handles high acoustic loads in a sealed enclosure. The thoughtful mounting system also allows secure fastening of both the subwoofer and the spare wheel with a single central bolt. With a height of only 145 mm, the subwoofer is suitable for most spare wheels from 15" diameter.

| The diameter of the subwoofer usedThe diameter of the subwoofer that is installed in the active box. | 11\" (280 mm) |
| RMS power of the amplifier | 150 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. | AB |
| Low-pass filter (LPF) | 50 – 150 Hz |
| 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. | 0 – 12 dB |
| 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. | 0° / 180° |
| Other | 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 |
| 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 |
| Loudspeaker type | Closed |
| What is the baffle made of?Active subwoofers can be made of MDF board, hardened plastic, sheet metal, aluminum or a combination of different materials. | Aluminum |
| Active subwoofer dimensions | Ø 500 x 145 mm |
