JBL Control 321CT Coaxial Ceiling Loudspeaker with HF Compression Driver 250 W

ลำโพงติดฝ้าเพดาน JBL CONTROL 321CT ขนาดดอกลำโพง 12 นิ้ว Kevlar-reinforced cone with 2″ voice coil, Coaxial ceiling speaker with 1″ HF, Built-in 70V/100V multi-tap transformer; 7.5W/15W/30W/60W 70V taps, 15W/30W/60W 100V taps, ทนกำลังขับ 250 วัตต์ power handling with high sensitivity and high SPL capability

The JBL Control 321CT is a coaxial point source design ceiling loudspeaker, equipped with a built-in 70V/100V multi-tap transformer, and featuring a 12″ low frequency cone performing as a waveguide for the high frequencies. The unique metal throat provides seamless transition to the horn, eliminating any aberrant HF “beaming”, and resulting in consistent 90° coverage on a broadband basis with true coaxial behavior.

Features:

  • Consistent 90° broadband pattern control.
  • Components
    • 300 mm (12 in) woofer with Kevlar-reinforcedcone with 50 mm (2 in) voice-coil.
    • 25 mm (1 exit) compression driver.
  • Extraordinary clarity for speech and vocals with extended frequency response for music.
  • 250 Watt power handling with high sensitivity provides high SPL capability.
  • Advanced high-slope crossover network for constant coverage and smooth, natural midrange.
  • Clean, contemporary grille and optional backbox available.
