Lines
The number of individual frequency bands played by the speaker. At least one specialized speaker is allocated for each such band.
The point of using multiple frequency bands is that for different frequencies, the optimal design of the speakers will also be different (for example, it is better to make tweeters small, and woofers large). Thus, dividing the sound into bands improves the sound. In turn, the advantage of
single-way speakers are compactness and lower cost.
Models for 2(LF / HF) or
3 bands(LF / MF / HF) are considered classic options for multi-band computer speakers. There are also
2.5 acoustics — it has 2 separate speakers for bass and treble plus a combined bass + midrange.
Frequency range
The range of audio frequencies supported by acoustics. The wider this range — the fuller the reproduced sound, the lower the likelihood that some of these details at low or high frequencies will remain “behind the scenes”. At the same time, the human ear is able to hear frequencies of the order of 16 – 22,000 Hz, and with age, this range narrows even more. In modern audio equipment, especially at the top level, there may be more extensive ranges, but from a practical point of view, this does not make much sense. In addition, it is worth noting that a wide frequency range in itself does not guarantee high-quality sound — a lot also depends on the frequency response.
