Zsound has been paying great attantion to create ultra-low frequency loudspeaker, for the LF is the essence of music, and the subwoofer is the natural extension for the system. The procedures of the designning include: Large numbers of the linerity and nonlinerity surveies, AES power mesurement, detailed computer modleing, complete prototyping, and exhaustive comparative analysis. And then, the specifically designed OEM procedure can efficiently optimise the performance of the bandwidth, as well as the whole system. Therefore, Zsound subwoofer is the optimal complement and extension for Zsound.
S218B subwoofer can be used in conjunction with P15, P12, and P10, and it can make the sub-frequency extend to 32Hz.
S218B is a bass reflex regulating enclosure, which comprises two 18 inch point-blank loudspeakesr to supply excellent cone covarage, and ultra-low thermo-compression, even function in ultra-high sound compression. The advanced design of the reflex enclosure provides more advantages for the bass energesis compared with before.
The S218B more comtemporarily coupled with the lastest riser vent has increased 3dB SPL output.
