JBL JRX212D ตู้ลำโพงมอนิเตอร์เวที 12 นิ้ว 2 ทาง 1,000 วัตต์
The JRX212 from JBL is a two-way 12″ loudspeaker system. It is suitable for live sound and speech reinforcement applications, and can also be used for monitoring on stage. It features a 2.5″ voice coil and a 1″ compression driver, as well as a frequency range of 60 Hz to 20 kHz.
Its high-frequency driver is protected by a SonicGuard system, while the speaker’s overall MDF construction allows for both durability and a suitable low-frequency response. With its non-resonant steel handles, the 43 lb speaker is easier to move around than if it had no handles at all. For connections, this loudspeaker sports 1/4″ TS and Neutrik SpeakON terminations.
Features:
- JBL 12 in low frequency driver with a 64 mm (2.5 in) diameter edgewound ribbon voice coil which provides more cross-sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling.
- JBL 2414H-C 25 mm (1 in) polymer diaphragm compression driver improves high frequency performance as well as system reliability.
- The advanced network topology crossover design shapes frequency response and delivers “coherent summation” in the crossover region.
- High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating.
- Progressive Transition™ high frequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response.
- The rugged, acoustically superior enclosure is constructed from 19 mm (.75 in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance.
- SonicGuard™ protects the high frequency driver from excess power without interrupting the performance.
- Non-resonant, all-steel handles are used.
- Attractive 18-gauge hexagon perforated, steel grille protects components from damage.
- Dual-angle pole-mount socket allows the speaker to tilt 10°for more uniform audience coverage.
