1.line array speaker 2.Birch plywood, Water-proof 3.CE, ROHS certifica 4.neodymium-magnet , reliable 5.good after sale service 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. DESCRIPTION and APPLICATION 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 15â 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( ± 2) 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 2à 10" ( 260mm) neodymium woofer 75mm( 3in) coil Components 2à 15" ( 380mm) neodymium woofers 100mm( 4in) coil( W-250A) Nominal impedance 16 ohm 4 ohm( W-250A) HF section 2à 2" neodymium compression driver with 51mm titanium diaphragm Nominal impedance 16 ohm Output section 2-channel Dispersion pattern 110° Hà 9° V Finish Water-proof, wear-resistant textured black paint Array design Arrays of less than 3à W-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 2à NL4MP speakon Recommend crossover LF 45Hz-1200Hz HF 1200Hz-20KHz 35Hz-120Hz( W-250A) Dimensions 855à 293à 600mm( Wà Hà D) 855à 610à 820mm( Wà Hà D) ( W-250A) Package dimensions 925à 360à 670mm/ 0.22cbm 925à 680à 890mm/ 0.56cbm( W-250A) Enclosure Birch plywood Net weight 42kg ( W-210A) / 81kg ( W-250A) Gross weight 45kg ( W-210A) / 84kg ( W-250A)
