Hifonics VRX1000A active subwoofer

Active Subwoofer Hifonics VRX1000A

Hifonics expands its range with powerful under-seat subwoofers VULCAN VRX available in 20 and 25 cm sizes with an all-aluminum body. These subwoofers are attractive not only for their price but also for their high-quality construction and full features that Hifonics fans worldwide appreciate. Unlike many cheap under-seat subwoofers that often use budget amplifiers or cheap integrated circuits, both new models feature full Class A/B Mosfet output stages, which are very stable under load and always deliver sufficient power. With a maximum power of 250 W for the 8" (20 cm) model and 300 W for the 10" (25 cm) model, they effectively drive the special low-frequency drivers. The subwoofers also have extra strong membranes that withstand high pressure created in small acoustic enclosures by air compression. Standard bass membranes would crack under such conditions. Thanks to the adjustable low-pass filter, bass boost, switchable phase shift, and remote bass volume control, the connection to the system is nearly perfect. Both models also have a high-level input with automatic turn-on, allowing them to be connected to factory car radios without a cinch output.

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.	150 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.	300 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.	A/B
The diameter of the subwoofer usedThe diameter of the subwoofer that is installed in the active box.	10\" (25 cm)
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.	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.	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.	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
Loudspeaker type	Closed
Active subwoofer dimensions	262 x 83 x 345 mm
