Comparison DLS 962 vs DLS 960

The number of separate frequency ranges into which the total frequency range reproduced by the speaker is divided. In this case, a separate speaker (or even several) is allocated for each range (band). the optimal speaker parameters for each band are different. Therefore, multi-band speakers are considered to provide better sound quality than full-range speakers. In modern multi-band car audio, 2(HF / LF) or 3(HF / MF / LF) bands are usually provided.

The total audio frequency range reproduced by all speaker speakers.

Obviously, this range should not be too narrow, so that the acoustics do not cut off the lower and/or upper frequency limits of the reproduced sound. At the same time, the human ear perceives sound within 16 Hz - 22 kHz, and it simply does not make sense to provide speakers with a wider frequency range. We also recall that in mid-frequency acoustics and tweeters, reproducible frequencies are limited due to specialization (for more details, see "Type"). And the overall sound quality will depend not only on this indicator, but also on a number of other features.

A crossover is a part of the speaker system that divides the overall signal into separate frequency bands that are fed to the corresponding speakers (for more details, see "Number of bands"). All multi-band speakers have their own crossover (component and coaxial, see "Type"); it is usually placed directly in the speaker cabinet. However, in some models, usually the most advanced, the crossover can be made as a separate device, in its own case. It is believed that such crossovers provide better sound quality and introduce less distortion into it; in addition, they often provide the possibility of fine tuning the sound.

The diameter of the tweeter (speakers) provided in the design of the speaker.

The diameter affects the amount of space needed to install the speaker. However, large cones are not needed for high frequencies, so this dimensions is usually small and does not really affect the overall dimensions of the speaker. The only exception is separate tweeter tweeters (see "Type"), where the overall dimensions of the cabinet are directly related to the dimensions of the cone.

The diameter of the midrange speaker(s) provided in the speaker. Midrange in this case may also mean a combined woofer/midrange speaker or an emitter of broadband acoustics (see "Type").

The size of the midrange speaker is often a key parameter that determines the overall dimensions of the acoustics and, accordingly, the requirements for its installation location. Exceptions can only be found among models with separate woofers (see below). But from the point of view of acoustics, a larger size allows you to achieve higher power and richer sound, including on bass.

The mounting depth of car audio is, in fact, the size of the speaker in depth. Note that for component sets (see "Type") this parameter is given for the largest speaker, and for case models it is generally irrelevant.

The mounting depth, along with the diameter of the speaker (see above), determines the amount of space needed to mount the speaker — in this case, how deep a niche would be required for normal mounting. At the same time, the larger the speaker, the larger, usually, the installation depth. And with similar diameters of equal size, a more powerful model is likely to be more “deep”.

The smallest amount of space — up to 15 mm deep — is required by some tweeters. A depth of 16 – 30mm is normal for tweeters and very shallow for general range speakers, most of these models have a depth of 30mm or more. At the same time, full-range speakers are usually "recessed" by less than 60 mm, component systems — by less than 90 mm, and more depth may be required only for some coaxial and mid-range models and, oddly enough, tweeters.
