320:", albeit at a relatively low level. A full range driver may have reduced output at both ends of its frequency range, or a more severely limited frequency response, resulting in a more compromised sound. Partisans of full-range loudspeakers claim superior phase coherence, while some critics describe them as midrange speakers working at or beyond their limits. Some full range drivers have been developed using 12" and 15" drivers, e.g. Audio Nirvana, and have overcome the bass limitations of smaller drivers using bass reflex cabinets. Also, as most adults cannot hear above 15 kHz the lack of high end frequency is generally not an issue with modern well designed full range drivers.
187:. Often the cone structure includes optimizations to enhance high-frequency performance. For example, a small low-mass horn or whizzer cone can be mounted where the voice coil and diaphragm meet, thereby increasing the output at high frequencies. The shape and materials used in the cone and whizzer are highly optimized. Manufacturers strive to optimize the materials, design, and construction of each component to achieve optimal performance and audio fidelity. Advanced technologies such as neodymium magnets, voice coil cooling systems, and wave guides further enhance the speakers’ capabilities, ensuring accurate sound reproduction and minimizing distortion.

augmented by a separate sub woofer or by a special cabinet design for low frequency reinforcement. These requirements usually mean that the full-range must have good sensitivity (for lower frequencies) with a light voice coil (for high frequencies) – these speakers commonly use a larger or more powerful magnet than usual, which improves sensitivity and thus lowers the power requirement at low frequencies as well as allowing a lighter voice coil. In addition, many have limited maximum excursions, requiring special enclosures which do not require large excursions at low frequencies for reasonable low end output.

small (typically 115 mm (4.5")) diameter full-range drivers into miniature enclosures, and many of these include 25 or 70-volt line transformers, for use on commercial sound systems employing long speaker cables. Some full-range speaker systems are designed with limited-range drivers, and must be used with equalizers to flatten and extend their frequency response, while others achieve acceptable response without electronic assistance. There are full-range speaker systems using up to 15" single drivers.

frequencies, aluminium in the middle area, and titanium at the neck zone, to produce high frequencies. Slits in the paper area of the cone, covered with silicone damping, together with internal foam pads provided mechanisms for tailoring the frequency response to be as flat as possible. Loudspeakers using the Walsh driver are still in production, though they have adopted a tweeter so no longer qualify as full-range drivers.

A German company, Manger, produces an unusual full-range driver in the form of a differentially flexing flat diaphragm driver, about eight inches in diameter. Manger claims performance, both maximum level and extended low frequency response, which is rather better than traditional full-range drivers.

In some designs, the main diaphragm may be coupled to the voice coil using a compliant bond such that high frequency vibrations are not transmitted into it, but instead move the whizzer cone. The technique of using a compliantly coupled (or modified) diaphragm for the low frequencies and auxiliary

and announcements to workers and visitors in retail stores, and public spaces. While these drivers are classed as 'full-range', it may be more accurate to term them 'wide-range' drivers, since their output abilities rarely extend to the extremes of the frequency range. Several manufacturers build

Another unusual full-range driver design is the Walsh driver, popularized in Ohm hi-fi speaker systems, where they reproduced almost the entire audible range of frequencies. Early Walsh units were large and expensive. These drivers used a single cone made with paper at the base, reproducing low

Another arrangement uses a radiating dome in place of the usual dust-cap; it is acoustically active. In most speaker drivers such dust-caps are constructed so as to be relatively acoustically inert. Sometimes the dust-cap takes the form of a small conical shape, claimed to improve dispersion at

Since every electronic, mechanical or acoustical component in reproduction chain will, regardless of purpose, degrade fine detail, the fewer components between the amplifier terminals and the listening room, the better. This includes conventional "mid-kilohertz" crossovers, which, in addition,
202:
Since the requirements of a full-range driver include both good low and high frequency response (which are contradictory in terms of physical construction), a full-range driver is usually limited to covering the audio spectrum above perhaps 100 Hz—leaving lower frequencies to be handled /
237:
A variation on the Walsh driver from a company called German
Physiks, based in Maintal near Frankfurt, is available in two forms. One uses a cone made from titanium foil 0.025 mm thick and an improved version that uses 0.15 mm thick carbon fibre. These are used in their range of audiophile

Full-range drivers are seen in applications ranging from televisions and computer speakers, to hi-fi speaker systems. The performance of the driver is substantially affected by their enclosure, and enclosures vary from mundane beige plastic boxes, at the low end of the scale, to large

Critics of full range drivers cite their inability to reproduce the full range of audio frequencies at similar amplitudes, leading to inaccurate reproduction of the audio signal sent to it. Reproducing multiple frequencies with the same diaphragm can increase
