Passive membrane – innovative technology for powerful bass
The passive diaphragm is a popular element in modern speaker systems that helps produce low frequencies without additional amplifier power. Instead of a traditional tweeter or woofer, it uses a passive driver that is caused to vibrate by the air pressure inside the cabinet.
What is a passive radiator?
If you've ever wondered what a passive radiator actually is, we can offer you a simple passive radiator explanation: A passive radiator is essentially a speaker without a drive coil or magnet. The principle of the passive radiator is based on resonance, which improves bass reproduction. The passive radiator structure consists of a membrane that is driven by the internal air pressure of the speaker box.
Modern loudspeaker systems
Modern speaker systems rely on the combination of various technologies to create an optimal sound experience. A portable speaker system uses compact and lightweight materials, while speaker components such as the tweeter and woofer are perfectly coordinated. Speakers with passive radiators offer particularly efficient bass reproduction.
bass reflex port – for powerful bass
The bass reflex principle is another technique for improving bass reproduction. A bass reflex tube is integrated into the housing through which the air generated by the loudspeaker can escape. A bass reflex loudspeaker uses this principle to increase the sound pressure and reproduce low frequencies better.
Active speakers – integrated amplification for perfect sound
Active loudspeakers are loudspeakers that have an integrated amplifier. The active loudspeaker driver therefore receives the amplified signal directly. The active loudspeaker function usually also includes the implementation of crossovers and equalizers. The active loudspeaker structure is particularly compact because no external amplifiers are required.
Frequency range loudspeakers – clear performance in every range
The speaker frequency range defines which frequencies the speaker can reproduce. A speaker crossover ensures that low frequencies are directed to the woofer and high frequencies to the tweeter. The right balance between woofer frequency and tweeter frequency is crucial for a harmonious sound.
Chuffing noise – avoid disturbing sound effects
A chuffing noise often occurs in loudspeakers with a bass reflex port. Bass reflex chuffing, also known as tube noise, occurs particularly at high volumes when air flows through the bass reflex tube. One of the disadvantages of bass reflex is the occurrence of these noises.
Speaker cabinet – crucial for sound quality
The speaker cabinet plays a major role in sound reproduction. A wooden speaker cabinet often offers a warm sound. Different speaker cabinet materials such as MDF or plastic also influence the sound characteristics. When it comes to the passive membrane speaker cabinet, the choice of material is particularly important in order to minimize vibrations.
Efficient bass reproduction – powerful bass for every music genre
Efficient bass reproduction requires a well-tuned woofer. The woofer efficiency depends on the construction and the materials used. In order to optimally reproduce resonant tones from loudspeakers, the use of a passive radiator can be useful.The bass passive radiator enables deep and powerful bass reproduction.
Resonance frequency – the key to precise bass
The resonant frequency of a loudspeaker is the frequency at which a loudspeaker or passive radiator works most efficiently. By optimizing the frequency range, you can ensure that different loudspeakers work together harmoniously in a system. Low frequencies are reproduced particularly powerfully and cleanly by precisely tuned resonant frequencies.
