Description and Application W-210A is a line array speaker which is made of two 10'' neodymium woofers, two 2'' titanium neodymium compression drivers and high-performance low-distortion compression driver with innovative horn design of waves phase philosophy. It is a zero interfere line array with multi- speaker combined to produce accurate directivity and maximum dynamic impact. Wherever low frequency extension is required, a W-210A will integrate seamlessly with W-250A line array sub-bass system in a standard configuration. Each enclosure is equipped with rigging system, allowing flown array to be constructed rapidly and safely. W-210A is very versatile and scalable for a wide range of applications in touring performance, corporate and fixed installation fields. W-250A is dedicated high performance sub-bass system designed to augment the low frequency output of the W-210A, W-250A is a sub-bass enclosure which must be flown with W-210A. So its physical dimensions are identical to the W-210A and it is equipped with the same proprietary rigging system. It features with twin 15¡± neodymium woofers with magnet structure and suspensions engineered for maximum linear excursion Model W-210A/W-250A Type Line array system Line array sub-bass system(W-250A) Frequency Response 55Hz-20KHz 3dB 40Hz-150Hz 3dB(W-250A) Directivity index(Dl) 12(¡À2)1.2KHz-16KHz Power handing LF 500W(RMS)1000W(PEAK) HF 160W(RMS)320W(PEAK) 1200W(RMS)2400W(PEAK)(W-250A) Sensitivity LF 99dB(1W@1M) HF 108dB(1W@1M) 112dB(1W@1M)(W-250A) MaxS.P.L LF 127dB(PEAK/1M) HF 127dB(PEAK/1M) 143dB(PEAK/1M)(W-250A) LF section 2¡Á10"(260mm) neodymium woofer 75mm(3in)coil Components 2¡Á15"(380mm) neodymium woofers 100mm(4in)coil(W-250A) Nominal impedance 16 ohm 4 ohm(W-250A) HF section 2¡Á2"neodymium compression driver with 51mm titanium diaphragm Nominal impedance 16 ohm Output section 2-channel Dispersion pattern 110¡ãH¡Á9¡ãV Finish Water-proof,wear-resistant textured black paint Array design Arrays of less than 3¡ÁW-210A will provide poor dispersion control and are neither recommended nor supported Speaker cables LF 1(+)1(-) HF 2(+)2(-) 1(+)1(-) (W-250A) Rigging system Please refer to the W-210A user manual before any operation Input connectors 2¡ÁNL4MP speakon Recommend crossover LF 45Hz-1200Hz HF 1200Hz-20KHz 35Hz-120Hz(W-250A).
