A full-range speaker is a device that is capable of producing a wide variety of frequencies. The design of the full-range speaker has great influence over the overall sound quality. It’s worth mentioning that sound frequency is measured by the number of times that the audio signal rises and then falls within a second. Quality speakers are built-in both high frequencies and low frequencies. The human ear is able to perceive frequencies in a range between 20Hz and 20kHz.
Full-range speakers cover the entire range of the human voice. Most full-range speakers have a low-frequency of 60Hz. Larger units with 15” drivers can achieve low-frequencies while devices with 10” drivers can achieve frequencies closer to 100Hz. The high-frequency range can extend to 18kHz, so smaller speakers with very low-mass high-frequency drivers will have a range an extension above the high-power systems. It’s worth mentioning that these units have heavier diaphragms to make room for their power requirements. The low-frequency range of these systems might overlap the subwoofers.
A full-range speaker involves a single driver or voice coil that is used to move and control the diaphragm. The full-range speaker has a cone structure which includes optimizations to enhance a high-frequency performance. Full-range speakers must have both a high and low-frequency response that covers the entire audio spectrum. The high-frequency end might include a light voice coil, whereas the low-frequency end includes a cabinet design. Most full-range speakers include several drivers to improve the listener’s experience.
Full-range speakers provide a great sound experience. The elimination of the crossover gives this speaker more power, as well as better quality and detail in the mid-level tones. Because of their unique features, commercial full-range speakers might be quite expensive and rare, hence, some audiophiles might decide to assemble their own units.
