คำอธิบาย

JBL Control 24CT Background/ Foreground Ceiling Loudspeakers 80 W

ลำโพงติดฝ้าเพดาน JBL Control 24CT เป็นลำโพงแบบ 2-Way มีขนาดดอดลำโพง 4 นิ้ว Woofer, เสียงแหลม 0.75 นิ้ว titanium-coated polyester tweeter, ทนกำลังขับ 80 Watts Power capability 16Ω, ตอบสนองความถี่ 80 Hz – 20 kHz

The Control 24CT is constructed with a coaxially mounted 4″ woofer with butyl rubber surround and 0.75″ titanium coated diffraction-loaded tweeter. It includes a 30W multitap transformer for use in either 70V or 100V distributed-line systems.

Taps are selected by a front-panel rotary switch. The transformer effectively limits the power to the speaker, so overload is not a concern.

  • 4″ woofer and 0.75″ titanium-coated tweeter
  • Extremely wide 130° coverage
