Acoustique Quality PONTOS W Active Subwoofer for Home Cinema or Stereo System / Black HIGH GLOSS Lacquer, Acoustique Quality

AQ Pontos W From the sound heard by the human ear, it follows that the amount of energy needed for the same sensation of low frequencies is much greater than the energy that is sufficient for medium and high frequencies.. The lowest frequency is proportional to the size of the speaker diaphragm and the internal volume of the chamber. For smaller-sized columns, it is physically impossible to carry the lowest bass. The solution is to add an active subwoofer – a special speaker for reproducing the lowest bass frequencies. Acoustics and the physiology of sound reception by the human ear play an important role. The ear very precisely perceives the direction from which higher frequency sounds come. The survival of our predecessors depended on whether they heard the hiss of a snake or the rustle of leaves of an approaching beast. High frequencies propagate as a narrow beam, at mid-tones the narrow beam turns into a cone, and low tones propagate spherically. This means that at low bass frequencies up to around 100 Hz, we are unable to determine where they come from. The moment we place classic full-range speakers (main) and the subwoofer behind the listeners, the ear will perceive the space of the main speakers in front of the listener as the source of sound. This effect is used in multi-channel home theater systems and can be applied equally advantageously for stereo listening in cases where it is not technically possible to place large speakers in front of the listeners.. Modern AV receivers are equipped with a special signal output for the subwoofer, where the entire bass line for the entire recording is added in a single audio channel.. The solution with an active subwoofer also has the advantage that the amplifier is not so heavily loaded, and the active crossover in the subwoofer compensates for the frequency response. The AQ Pontos active subwoofer is equipped with a robust 12-inch speaker from the prestigious Peerless SLS series. The speaker in the enclosure is directed towards the floor. Such placement of the speaker in the enclosure is aesthetic, supports stronger bass propagation, and at the same time protects the speaker diaphragm from damage. The bass-reflex port is also directed towards the floor. Its internal construction resembles the shape of the letter Y, which significantly lengthens its channel relative to the housing itself. The top part of the housing is a sandwich panel with active BDS resonance damping. (Balls Damping System).The subwoofer amplifier is built into a separate chamber that is isolated from the internal volume of the subwoofer. The enclosure construction is made of 18 mm thick MDF boards, the rigidity is further increased by an eight-layer lacquer. The subwoofer is mounted on four steel spikes, which limit the transmission of resonances to the floor.
