Coaxial Columns
Coaxial acoustic is a common version of car dynamics that lose all ranges. Such dynamics are much cheaper and easier to install, compared with the component acoustic. If you don't listen to the reproduction of every sound and instrument, and you want a quality couple to your magnetoly, coaxial dynamics for you. They can be used in a complex acoustic system as dynamometers for installation in the rear shelf. In any case, a coaxial acoustic of a reliable producer who knows the sound of a car sound will allow you to enjoy a vivid reproduction of the music you love.
Coaxial acoustic design
Coaxial acoustic design is a dynamic consisting of a NH-diffusor and a tip--- PM-dynamic. They're on almost one axle so the sound streams can be reconciled. Coaxy dynamics include a built-in crossover that controls the division of ranges. Advanced dynamics may include a separate design of PM, which is as close as possible to the component acoustic. But the price of the 3-poly coaxial acoustic is higher than 2-poly.
When selecting, draw attention to the design of the diffuseor and the HF endpoint, this will depend on the nature of the lost music. Metal diffuses are brighter and brighter, but they are unable to fully deliver the velvet and natural sound, guitars, so it is better for NF and PH bands to read softer and elastic diffuses. The PHD is dependent on your preferences, you choose metal or pulp/silk.
It is better to draw attention to the filtering of the frequency within which the condenser can act, but there is no need for special hope of quality.
