Some designs complement cone controllers with special tweeter elements. The resulting dispersion properties can make them a good choice for installations with hard, reflective surfaces or larger reverberating spaces. The physically narrow design of the speaker housing makes it possible to function well in Gothic forms of architecture, as they can be mounted and mixed with the columns of the building.

Even if you’re not familiar with a speaker loaded with a horn, chances are you’ve seen one in person or even in old movies or cartoons. The speakers are designed to increase the sound of the low-power amplifiers using a speaker. While you can see some speaker systems with a polygonal shape, many speaker systems full of horns now resemble other speakers. However, they still use a flared transmission channel in the speaker cabinet to create a louder sound. Line array speakers point directly to the audience and use sound diffraction.

The vibrations of the eardrum are sent to our brain as electrical signals and then interpreted as sound. Surround sound is a way to enhance the fidelity and depth of sound percussion by using multiple audio sources from the speakers, specially placed to wrap the audience in sound. Surround sound is fashionable after previous sound setups (mono, binaural recordings or stereophonic systems) and adds more audio channels to your system to create a more immersive experience.

Mobile iron drivers are inefficient and can only produce a small soundtrack. A driver with a higher maximum power cannot necessarily be driven to higher levels than lower power, because sensitivity and power handling are largely independent properties. For the first example, one speaker that is 3 dB more sensitive than the other produces twice the sound power for the same input power. For example, a 100 W (“A”) controller with a sensitivity of 92 dB to 1 W @ 1 m emits twice the sound power of a 200 W (“B”) controller with a rated power of 89 dB for 1 W @ 1 m when both are powered with 100 W input power. In this particular example, when used at 100W, Speaker A produces the same SPL or volume that Speaker B would produce with a 200W input.

The current in the magnetic field causes it to move the cone to produce sound. A specifically organized combination of the above speakers, a surround sound system is the best way to bring excitement from the cinema to your listening room. Many bookshelf speakers offer enough bass response to listen to music, although anyone building a home theater setup will want to add a subwoofer. Because bookshelf speakers are smaller, you might think they need less power than portrait speakers, but that’s not always the case: some shelf speakers can even consume more power than sensitive upright speakers.

In 1954 Edgar Villchur developed the acoustic suspension principle of loudspeaker design. This allowed for a better bass response than previously could be obtained from controllers mounted in larger cabinets. He and his partner Henry Kloss founded the company Acoustic Research to produce and market speaker systems using this principle. Subsequently, continuous developments in the design and materials of the enclosure led to significant audible improvements. The four main types of speakers found in the home today are traditional speakers, wall/ceiling speakers, soundbars, and subwoofers.

Instead of a voice coil that drives a speaker cone, a magnetostatic speaker uses a series of metal strips attached to a large film membrane. The magnetic field produced by the signal current flowing through the strips interacts with the field of permanent bar magnets mounted behind it. Usually, these designs are less efficient than conventional audio equipment rentals moving coil speakers. Designing speaker systems is both an art, involving subjective perceptions of timbre and sound quality, and a science, involving measurements and experiments. Some of the issues that speaker and driver designers face include distortion, acoustic lobing, phase effects, off-axis response, and cross-artifacts.

This type of wiring error does not damage the speakers, but is not optimal for listening. Passive crossovers are often installed in speaker boxes and are by far the most common type of crossover for home use and low power consumption. In car audio systems, passive crossovers can be in a separate box, necessary to accommodate the size of the components used.

This is the box that contains the controllers and other electronic components. Sound would exist even without the case, but there are a few reasons to use it. The first reason is the most basic: it is more convenient to install everything in a compact box. It is believed to eliminate vibrations from the conductor and process the air pushed behind the cone of the conductor. The diaphragm vibrates due to the movement of the voice coil: it pushes the air into our ears, but also pushes it into the housing.
