JBL Control 328C Coaxial Ceiling Loudspeaker 250 W

ลำโพงติดฝ้าเพดาน JBL Control 328C เป็นลำโพงแบบ 2-Way มีขนาดดอกลำโพง 8 นิ้ว Kevlar-reinforced cone with 2″ voice coil, shaped mounting baffle provides pattern cintrol of 12″ horn from 8″ driver, ทนกำลังขับ 250 วัตต์ at 8Ω, ตอบสนองความถี่ 60 Hz – 16 kHz, +/-3dB

The JBL Control 328C is a coaxial 250-watt point source design ceiling loudspeaker, featuring an 8″ 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 120° coverage on a broadband basis with true coaxial behavior.

Features:

  • Coaxial ceiling speaker with 1″ HF compression driver and consistent 120° broadband pattern control
  • 8″ Kevlar-reinforced cone with 2″ voice coil, shaped mounting baffle provides pattern cintrol of 12″ horn from 8″ driver
  • 250-watt power handling with high sensitivity and high SPL capability
  • Advanced high-slope crossover network for constant coverage and natural midrange
  • Baffle equipped with EZRail(TM) feature, holds baffle in place while securing to backcan with screws
  • Removable multi-pin locking connector with screw-down terminals for simplified pre- or re-wiring during installation
  • Recommended for applications requiring speech and vocal clarity, extended frequency response for foreground and background music
