DS18 69PRO400NMR-4 6x9 in. Neodymium Mid-Range Loudspeaker 200W RMS 4-Ohm

The DS18 69PRO400NMR-4 is a 6x9" high-sensitivity professional mid-range loudspeaker (midrange speaker) built for high-output car audio, SPL and pro audio systems. It has a neodymium motor and handles 200W RMS / 400W max at 4 ohms. It is made to deliver clear, forward vocals and instruments in loud systems.

Key Features:

• High sensitivity: 100 dB (1W/1m) turns amplifier power into more output.
• Neodymium magnet motor: improves efficiency and keeps weight down.
• Frequency response: 100 Hz to 17 kHz.
• Voice coil: 1.5" (38.6 mm) Kapton former with CCAW winding.
• Copper demodulating ring: reduces distortion for tighter, more controlled mids.
• Construction: paper cone, paper dust cap, cloth surround and a black steel basket.
• Mounting depth: 2.9".
