Electrodynamic Speakers

  Electromagnetic Speakers History   Back in the early part of the 20th century, people were still exploring the basic knowledge of math and frequencies. While the electromagnet part of the speaker originates from the 1860s, it took 40 more years to develop...

Digital Speakers

What are Digital Speakers?   Digital speakers or Digital Sound Reconstruction (DSR) systems are a form of loudspeaker technology. You should not confuse them with modern digital formats and processing. This is because engineers still have not developed them as a...

Rotary Woofers

Generally, human beings can’t detect sounds below 20 Hz. This is why the stated frequency response of many products is from 20 to 20,000 Hz. Part of this impression comes from the challenges in using traditional cone and voice coil subwoofers to produce these...

Monitor Isolation Pads

What are monitor isolation pads?   Music producers and sound engineers use various devices to decouple the monitors from the surface. Accordingly, most widespread are monitor isolation pads made of dense acoustic foam and metal spikes on which the speakers rest....

Resonance Absorbers

What are resonant absorbers?   The resonant absorbers are frequency-dependent because of the desired resonance of the material at a particular wavelength. Different types of resonant absorbers are the Salisbury screen, the Jaumann absorber, the Dallenbach layer,...

Membrane Absorbers

What are Membrane Absorbers?   Membrane absorbers, also known as panel and diaphragmatic absorbers, utilize the resonant properties of a membrane to absorb sound over a narrow frequency range. Engineers typically employ unperforated, limp panels of wood, pressed...
