Active subwoofer Hifonics VRX82A
The flat, rounded shape of the package of the new VULCAN VRX82A active system allows it to be installed in the spare wheel well. The highlight of the new VULCAN system is the quasi-resonant passive radiator, which, in addition to the actively controlled woofer, ensures additional air displacement, which is important for low frequencies. The VRX82A has an advantage here, as conventional bass reflex enclosures tend to generate flow sounds in the reflex port, which also takes away valuable internal volume. Not so with systems with passive radiators, which act as a bass reflex channel -- only without annoying background noises. Operating at over 80% efficiency, the integrated Class D amplifier provides a high output of 200 watts RMS and provides an efficient digital power supply to the subwoofer.

| 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. | 200 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. | 400 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. | 2 x 200 mm (8") |
| Low-pass filter (LPF) | 50 - 150 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. | Ano |
| 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. | Ano |
| 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. | Ne |
| 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. | Ano |
