Beschreibung
The Alpair 12PW is a high-quality woofer/midrange driver from Mark Audio that was specially designed for all serious music lovers. With its audiophile, paper and glass fiber reinforced membrane and the broadband sister drivers 6P, 10P and 12P, it sets new standards in terms of sound neutrality and detailed sound output. Its mid-high range drops gently above 10kHz, while the frequency response is kept flat throughout to make the acoustic representation as natural as possible. Features such as the lightweight paper membrane and the long-stroke suspension ensure a unique listening experience.
