รายละเอียด

NEXO RS18Ci Ray Sub 2X18″ Carpeted Version

ลำโพงซับเบส NEXO RS18Ci ขนาดดอกลำโพง 18 นิ้ว 2 ดอกแบบตัวตู้หุ้มพรม รองรับกำลังขับของเครื่องขยายเสียงได้ 3500-8000 วัตต์ 4โอหม์, Frequency Response @ -3db [a] 30Hz–100Hz,  Impedance 2 x 8Ω

The RS18 uses two 18″ long excursion Neodymium drivers drivers in a low profile cabinet to extend system response down to 30Hz. NEXO’s patent pending RAY SUB Technology is based on optimising the positioning and phase relationships of radiating surfaces in vented enclosures, permitting acoustic distance from rear to front sections to always increase as frequency decreases.

Consequently rear and front sections sum up efficiently over the entire subwoofer bandwidth, allowing for an average of 5dB gain from the rear section in the forward direction and cancelling in the rear direction.

Features:

  • Low profile, high output, modular scalable bass
  • Configurable directivity pattern
  • Cardioid pattern reduces rear levels by minimising rear/side wall reflections
  • Aerodynamic profiled vents with 20db noise reduction and improved linearity at high SPL
  • Frequency response 30Hz – 100Hz
  • Sensitivity 105dB
  • 2 x 18″ configuration
  • Applies across entire NEXO Product Line
