Description

Product Overview

Get clear, present midrange output from the DS18 6PRO300MR-4, a 6.5-inch high-sensitivity professional mid-range loudspeaker for car-audio systems. It handles 150 watts RMS at 4 ohms and features copper demodulating rings and a curvilinear cone.

Key Features & Benefits

High sensitivity: The 102 dB (1W/1m) rating supports strong output from the power applied.
Reduced distortion: Copper demodulating rings are designed to reduce harmonic and intermodulation distortion.
Broad dispersion: The curvilinear cone is designed to improve sound dispersion while maintaining efficiency.
Thermal design: A 1.25-inch (31.7mm) voice coil on a Kapton former supports high-power operation.
Straightforward wiring: Push terminals accommodate 8 AWG connections.
