ILF218B 美国C牌音箱 双18"低频超低音扬声器系统,40Hz-125Hz,800W RMS/2000W PGM,4欧姆有源散热器,Tuf-Coat黑色外壳,用作固定安装. The Community iLF218 is an efficient, dual 18 inch subwoofer that can be used with any full-range loudspeaker system. It has exceptional punch, high output, and low distortion. The iLF218 uses a unique combination of techniques to keep voice coil temperatures low to avoid power compression that causes reduced output at higher volume levels.
Active-Air cooling uses the bass ports to move outside air over the motor structures of each driver. Additionally, cone movement drives air through the vented magnet pole-piece to cool the motor structures. BCL (Balanced Cone Loading) improves the linearity of the system by balancing the front and rear air loads. The enclosure has rigid internal bracing that reduces sound energy losses from enclosure vibration.
