Description
Audison APBMW K4E BMW 2-way separate set
The separate kit designed for BMW and Mini cars improves the sound of the car and is really easy to install. Audison APBMW K4E creates an immersive sound world for your car and gives the music precision and color. The set includes a natural-sounding 4" mid-bass speaker with a paper cone and a 1.1" Tetolon dome tweeter, which supports the middle and upper frequencies of the 4" mid-bass and expands the sound field to the third dimension.
Increase performance by adding an amplifier
Although the APBMW K4E is suitable for playing with a car stereo amplifier thanks to its high sensitivity, the real potential is only realized when Audison's Bit series DSP amplifier, such as the AP4.9 bit, is harnessed to command the speakers. The amplifier naturally increases the amount of power going to the speakers, but the DSP found in it plays at least an equally important role, i.e. the digital signal processor, which can be used to modify the tone of the speakers to suit the ears of each listener.
Characteristics
1. Specially developed for BMW-Mini cars with a separate kit as standard.
