(BS-678) TOA BS-678 | ลำโพงติดผนังขนาด 6 นิ้ว 6 วัตต์

SKU : BS-678 TOA BS-678 ลำโพงติดผนังขนาด 6 นิ้ว 6 วัตต์nnThe BS-678, of which cabinet is made of wood, can be installed in a vertical or horizontal orientation. Either concealed in-wall wiring or exposed wiring can be used for speaker cable connection. The speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied to. The input impedance can be easily changed by changing the tap position of the transformer. Two built-in 6-inch double cone speaker units deliver high quality sound. The push-in type input connector makes cable connections easy and allows bridge wiring.nnSpecificationnn nnRated Input 6 W (100 V line), 3 W (70 V line)nRated Impedance 100 V line: 1.7 kΩ (6 W), 3.3 kΩ (3 W), 6.7 kΩ (1.5 W), 13 kΩ (0.8 W)n70 V line: 1.7 kΩ (3 W), 3.3 kΩ (1.5 W), 6.7 kΩ (0.8 W), 13 kΩ (0.4 W)nSensitivity 94 dB (1 W, 1 m) (500 Hz – 5 kHz, pink noise)nFrequency Response 150 Hz – 20 kHz (peak -20 dB)nSpeaker Component 16 cm (6″) double cone-typenApplicable Cable 600 V vinyl-insulated cable (IV wire or HIV wire)nSolid wire: φ0.8 – φ1.6 mm (equivalent to AWG 20 – 14)n7-core twisted wire: 0.75 – 1.25 m㎡ (equivalent to AWG 18 – 16)nConnection Push-in connector (bridging terminal)nFinish Baffle: HIPS, off-white (RAL 9010 or equivalent color)nCabinet: Particle board with pvc sheet, off-white (RAL 9010 or equivalent color)nGrille: Surface-treated steel plate net, off-white (RAL 9010 or equivalent color)nDimensions 250 (W) × 190 (H) × 110 (D) mm (9.84″ × 7.48″ × 4.33″)nWeight 1.7 kg (3.75 lb)nAccessory Speaker mounting screw (4 × 35 (0.16″ × 1.38″)) …2
