S1220 is a widely used high pressure high quality single 12 "two frequency reflection type full frequency loudspeaker.          

S1220 bass uses 1 only 12 "," 4 "voice coil high-power low distortion unit, installed in a large volume inverted phase trapezoidal box, low-frequency lower limit can be extended to 55Hz (-3dB). Treble part uses a 2 titanium film, aluminum flat wire voice coil high-power unit, installed in a coverage angle of 60 degrees x degrees of constant directivity of the horn, the high-frequency upper reaches of 19kHz (-3dB).           S1220 uses the phase correction of the crossover network, the low frequency and high frequency unit better smooth convergence, the frequency response and phase distortion to a minimum. High frequency divider unit installed on the network with over-current, overload protection circuit, the input power is too large, will be reduced to the power distribution automatic 3dB treble unit, the signal returned to normal after the protection circuit does not work automatically.          

Greatly enhance the sense of hierarchy and if the tone of the definition, more comfortable, smooth and broad range for you, meet different functional requirements.

S1220是一款应用非常广泛的高声压高品质单12"  两分频反射式全频音箱.
S1220的低音采用了1只12", 4"音圈的大功率低失真单元，安装在一个大容积的倒相式梯形箱体中，低频下限可延伸至55Hz（-3dB)。高音部分采用了一只2"钛膜,铝扁线音圈的大功率单元,安装在一个覆盖角度60° x 40°的恒指向性号角中,高频上限直达19kHz(-3dB)。
S1220采用了带相位校正的分频网络，使低频与高频单元更好地平滑衔接，频响与相位失真降至最低。高频单元分频网络上安装有过流、过载保护线路，在输入过大功率时，自动将分配给高音单元的功率降低3dB ,信号恢复正常后，保护线路自动不起作用。
大大地提高了音色的层次感以及中频的清晰度，为你呈现更舒畅、平滑而广阔的音域，满足更多不同功能的需求。
