What are the different types of transmitted subwoofers?

Unlike closed closed covers, the subwoofer covers surround the subwoofer low -frequency power to increase ventilation or port. This ventilation opening or holes inside these covers is usually made of cylindrical components such as PVC pipes. These speakers boxes are larger than sealed boxes and are more difficult to design and build them. Portable, only reflective zone, dual reflective zone and labyrinth boxes are four main types of ventilated attachments.

The term Ported cover can refer to any type of box containing ventilation, but most often used to describe a one -time closure containing one port. This type of ventilated cabinet is the easiest to design and build. The width, length and location of the port are determined by the frequency to which the cover is tuned. The debugging frequency determines how low the bass can pass and provide low -frequency limit value for the box. Any frequency below the limit frequency will not be heard and can be damaged withUbwoofer when playing sounds below this level.

The transmitted subwoofer covers that contain two chambers and one port are called the only reflective band boxes. This style is equipped with a subwoofer mounted to the wall inside the cover, pointing to a larger chamber in the box. The port is usually placed in a larger chamber and is located at the top of the box. The subwoofer outputs sound efficiently in the tuned frequency zone, while other frequencies are also not produced. This type of cover is difficult to build and users should remember that it is easy to damage the subwoofer without realizing it because the distortion is difficult to hear.

Dual Reflex Bandpass boxes consist of two chambers, two ports and a single subwoofer. Woofer plays a tuned, transferred chamber and efficiently reproduces frequencies in the tuned range. Frequencies outside the tuned range are cut off. These transferred subwoofer closed are large and obtIdentifiable. Even the smallest design or design error can have a noticeably negative effect, such as changing the box tuning.

transplanted sound pressure levels, more commonly called Bed -Bed (SP) boxes, are useful for applications with a narrow belt of subwoofer. This type of cover increases a specific frequency while filtering other frequencies. Loaded (SP) boxes are usually very large and contain one port and one chamber. An attempt to play a wide range of music frequencies through a subwoofer in a transmitted box (SP) can cause Woofer failure. Fortunately, the failure of the subwoofer can be avoided using a crossover that filters out undesirable frequencies with these types of ported subwoofers.

Labyrinth boxes are large and very difficult to assemble. This type of cover consists of one chamber with a maze similar to the inner port. Its design allows you to increase the specific frequency of ABOVE all others, but generally there are no practical applications for these transmissionnative subwoofer attachments.
