Exploring Common DIY Terminology - Full Range

Full Range

A full-range driver, also known as a wideband driver, is a type of loudspeaker driver designed to reproduce a broad range of audio frequencies without the need for a separate crossover network or multiple drivers. It is engineered to cover a wide frequency spectrum, typically from the low-midrange to the upper treble frequencies, all in a single driver unit. Full range drivers feature several characteristics that separate them from standard drivers:

• Whizzer Cone: Some full-range

Basket

The basket of a loudspeaker driver refers to the frame that supports and holds the various components of a driver together. It is an essential structural element that provides stability, rigidity, and mechanical support to the driver's components. The materials and construction of the basket have implications beyond just appearance, as resonances in the structure can impact frequency response and the shape of the structure can either limit or enhance the ability of a driver to...

Air Gap

Also simply referred to as "the gap," an air gap refers to the physical space between the voice coil and the magnet assembly within the driver. The air gap is an important feature of a driver's motor system and plays a crucial role in its operation. Here's how the air gap functions and its importance:

• Magnetic field generation: The air gap forms the core of the magnetic circuit in a loudspeaker driver. It helps create a uniform and concentrated magnetic field within

Dynamics

Dynamics refers to the ability of a loudspeaker system or component to reproduce a wide range of sound levels accurately and with impact. It encompasses the capability to accurately reproduce both quiet and soft passages as well as loud and powerful passages in music or audio recordings. Dynamics are essential for creating a lifelike and engaging listening experience. Some key aspects related to dynamics are listed below:

• Dynamic Range: Dynamic range refers to the difference

Infinite Baffle

The term 'infinite baffle' can refer to at least two different aspects of loudspeakers and loudspeaker design. The first is part of measuring and comparing loudspeaker performance. The second is a type of loudspeaker 'enclosure'. We'll take a look at both here.

Design and Measurement

The concept of the infinite baffle is a technique used in loudspeaker design and testing to eliminate the influence of the speaker's rear radiation on the measurement...

Impulse Response

An impulse response is a graphical representation of a loudspeaker's response to an ideal impulse signal. The impulse response is essentially the loudspeaker's reaction to a sharp and short burst of energy. It is a powerful tool for loudspeaker designers to assess the speaker's time-domain performance and identify various characteristics of its sound reproduction. Creating an impulse response graph for a loudspeaker requires specialized equipment and software for accurate...

Reactance

Reactance refers to the component of impedance that arises due to the reactive elements in the driver's electrical circuit. Reactance is a complex impedance that includes both resistance and reactance, with reactance having both inductive and capacitive components. Understanding reactance is essential in loudspeaker design and analysis, as it affects the electrical and acoustic behavior of the driver.

There are two types of reactance commonly encountered in loudspeaker...

Bandpass (Crossover Filter)

A bandpass filter refers to an electronic circuit or signal processing technique used to limit the frequency range of an audio signal that is sent to a specific driver or set of drivers within a loudspeaker system. It is employed to ensure that each driver operates within its intended frequency range and to achieve a desired frequency response for the overall system. For the DIYer, a bandpass crossover filter would typically be seen in a 3-way loudspeaker...

Cancellation

Cancellation refers to the phenomenon where sound waves from a loudspeaker system interfere with each other, resulting in a reduction of certain frequencies. This interference can occur due to several factors, including phase differences and spatial relationships between sound sources.

One common type of cancellation is known as phase cancellation. Phase cancellation happens when two sound waves of equal frequency and amplitude, but with opposite phase (180...

Efficiency

Efficiency refers to the ability of a speaker system to convert electrical power into acoustic output effectively. It measures how efficiently a loudspeaker converts electrical energy into sound energy. Efficiency is typically expressed as a percentage and represents the ratio of acoustic power output to the electrical power input. A more efficient loudspeaker requires less electrical power to produce a given level of sound output. Efficiency is influenced by several factors,...
