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是一款應(yīng)用非常廣泛的高聲壓高品質(zhì)單12"  兩分頻反射式全頻音箱.
S1220的低音采用了1只12", 4"音圈的大功率低失真單元，安裝在一個(gè)大容積的倒相式梯形箱體中，低頻下限可延伸至55Hz（-3dB)。高音部分采用了一只2"鈦膜,鋁扁線音圈的大功率單元,安裝在一個(gè)覆蓋角度60° x 40°的恒指向性號(hào)角中,高頻上限直達(dá)19kHz(-3dB)。
S1220采用了帶相位校正的分頻網(wǎng)絡(luò)，使低頻與高頻單元更好地平滑銜接，頻響與相位失真降至最低。高頻單元分頻網(wǎng)絡(luò)上安裝有過(guò)流、過(guò)載保護(hù)線路，在輸入過(guò)大功率時(shí)，自動(dòng)將分配給高音單元的功率降低3dB ,信號(hào)恢復(fù)正常后，保護(hù)線路自動(dòng)不起作用。
大大地提高了音色的層次感以及中頻的清晰度，為你呈現(xiàn)更舒暢、平滑而廣闊的音域，滿足更多不同功能的需求。
