passive radiator การใช้

• A passive radiator system can provide an improved bass sound.
• Passive Radiators : tunable, down firing, slot & mass loaded ( classic VMPS ).
• Bass reflex ports or passive radiators are not used because they affect the response and sound.
• To satisfy this requirement, passive radiators traditionally have a larger surface area than the active driver.
• Internal air pressure produced by movements of the active driver cone moves the passive radiator cone as well.
• The frequency response of a passive radiator will be similar to that of a ported cabinet, with two exceptions.
• The goal in designing a passive radiator is to adjust the tuning so that this notch is below audible levels.
• VMPS's passive radiators used a unique high-compliance suspension and a low moving mass diaphragm to achieve a low resonant frequency.
• However, like any passive radiator system, it is possible to damage the bass radiator by driving it beyond its mechanical limits.
• Internally, it features a rechargeable lithium-ion battery, four front-facing speaker drivers, and two opposing passive radiators ( one each front-and back-facing ).
• However, the amount of mass suspended on a passive radiator diaphragm enables extremely deep tuning frequencies to be possible in small enclosures.
• A passive radiator system makes it easier for the speaker system to create the deepest pitches ( e . g ., basslines ).
• Both bass reflex and passive radiator approaches are used with the same goal : to obtain better deep pitch sound from the system.
• With a PR system, the movement of the " drone cone " passive radiators reduces the amount that the woofer has to move.
• Passive radiators are considered to be similar in design to bass reflex systems, which use a port or vent cut into the speaker cabinet.
• The VMPS bass management system used one or more high-compliance down-firing passive radiators that was tunable by adding or removing putty from the diaphragm.
• Passive radiators are tuned by mass variations ( M mp ), changing the way their compliance interacts with motion of the air in the box.
• The parasitic elements are not electrically connected to the transmitter or receiver, and serve as passive radiators, reradiating the radio waves to modify the radiation pattern.
• According to a press release from Infinity, the FPS-1000 uses a slim-profile, advanced technology 5-inch woofer with a 5-inch passive radiator and a 1-inch-high performance tweeter.
• Among audio engineers, the term " monitor " implies that the speaker is designed to produce relatively flat ( linear ) passive radiator speaker to improve the low-frequency response.
