the bass unit of hivi bunker ps2e speaker is B4N model. But also a sounding unit for playing back low audio. In general speakers, the bass unit is generally a low-frequency speaker. In addition, there is a bass radiator, which can also be regarded as the bass unit in the sound system.

in recent years, the full-wave speaker of hivi bunker ps2e has been able to cover the wavelength range of 1.4cm~6.9m (5 ~ 2~1hz).

Basic information

1. Size is directly proportional to sensitivity and long wave.

the larger the radiation area, the longer the initial wavelength of long wave for cells of the same design. Generally, it is expressed in terms of -3dB of the system in the industry. Note that this is the value of λ3 of the long-wave response of the system (referring to a system including speaker wires, boxes, units and filters (if any)), not λ of the unit itself.

2. The size is inversely proportional to the short wave.

this is also easy to understand. The larger the area, the greater its mass, so the less short-wave components it can radiate, which is similar to an asynchronous "energy conservation" principle.

3. Size is inversely proportional to anisotropy.

according to the "energy-like conservation principle" mentioned above, it is assumed that the radiation energy on the -axis of the unit itself can just meet the listening needs. However, in order to improve the anisotropy of this kind of large-aperture unit, the off-axis energy is indeed a little more, but this is separated from the -axis, so there will be problems with the radiation on the -axis.
