Type of Broadband - to play all frequency ranges, use one universal speaker (from 40-50 Hz to 18 000-20 000 Hz). As a result, such a speaker is the cheapest and easiest to install, but the flip side of these advantages is the low sound quality. Component (diversity) - in such a speaker, a separate speaker corresponds to each frequency band. Thanks to this solution, the highest sound quality (“presence effect”) is achieved. At the same time, component speakers, due to the significant number of speakers, are expensive and difficult to install. Coaxial (combined) - the golden mean between the previous options: low-mid-and high-frequency speakers are combined in one housing. Thus, ease of installation and higher sound quality than broadband are achieved. The sound characteristics of coaxial speakers are lower compared to component acoustics. In addition, the complexity of adjusting the speakers increases. Mid - frequency - “cuts off” the highest and lowest frequencies and reproduces the middle range (usually 50-6000 Hz). Most often used with twitter. Case - the speakers of this speaker are mounted in the case, which facilitates installation. Minus - case acoustics require more space in the cabin. Speakers Mid-range speaker (Mid-range) - reproduces the middle frequencies (MF) in the range from 250-350 Hz to 6000-7000 Hz. Tweeter , tweeter (Tweeter) - best car speakers designed to reproduce high frequencies (tweeters) in the range from 1500-2500 Hz to 20 000-30 000 Hz. Woofer (Woofer) - reproduces low frequency (LF) band from 800-1000 Hz and 40-60 Hz. Subwoofer (Subwoofer) - a speaker that reproduces low frequencies in the range from 20-30 Hz to 400-600 Hz. Midbass (Mid-Bass) - a speaker that reproduces medium and low frequencies (MF / LF) in the range from 200-400 Hz to 3000-4000 Hz. Broadband is a universal speaker. Size Round 8 cm (3 inches), 10 cm (4 inches) - reproduce sound from 120 Hz. Place of installation - protective nets in the dashboard. 13 cm (5.25 inches) - reproduce sound from 100 Hz. Place of installation - kick panels, which are located under the dashboard, side latches of the rear shelf, doors. 16.5 cm (6.5 inches) - reproduce sound from 80 Hz. This option is most common. Place of installation - doors and rear shelves. 20 cm (8 inches) - rare. Oval 10x15 cm (4x6 inches) - are placed in the side clips or kick panel. 13x18 cm (5x7 inches) - mounted on the door or rear shelf. 15x23 cm (6x9 inches) - are found most often, are installed in the rear shelf or doors. Popularly, such speakers are called “pancakes”. 18x25 cm (7x10 inches) - rarely used, placed on the rear shelf. 20x30 cm (8x12 inches) - not available. The larger the speaker, the better it sounds low frequencies. For speakers without a subwoofer, speakers of size 16 cm are suitable. This is the best choice, since such speakers transmit well low, medium and high frequencies. For acoustics with a subwoofer, 13 cm speakers are selected. Smaller speakers do not reproduce the lower sound register well. The size of the subwoofer ranges from 20-40 cm.
