DS18 6PRO300MR-4 PRO 6.5” High Sensitivity Professional Mid-Range Loudspeaker 150 Watts Rms 4-Ohm (each)

The DS18 6PRO300MR-4 is a 6.5" high-sensitivity professional mid-range driver built for demanding car-audio installs, delivering 150W RMS into a 4-ohm load with efficient, clean output. Its copper demodulating rings and curvilinear cone are tuned for low distortion and broad dispersion at high excursion.

• Nominal Diameter: 6.5" (165mm) cone defines the driver’s footprint and midrange surface area for clear, articulate sound.
• Nominal Impedance: 4 Ohms — affects amplifier compatibility and damping, enabling strong, controlled playback with a wide range of car amplifiers.
• RMS Power Handling: 150W — continuous power rating guides amplifier matching to avoid thermal stress during extended listening.
• Max Power Handling: 300W — peak tolerance for transient musical peaks and test signals without risking damage.
• Sensitivity: 102 dB (1W/1m) — high efficiency means more output from modest power, enhancing perceived loudness in vehicles.
• Frequency Response: 100Hz–12.5kHz — covers upper bass through mid/high treble, influencing crossovers and enclosure design in a multi-way system.
• Demodulating Rings: Copper rings reduce harmonic and intermodulation distortion from voice-coil movement, yielding cleaner, more linear output at higher levels.
• Cone Shape: Curvilinear cone for improved dispersion without sacrificing efficiency.
• Terminals: Push terminals (8 AWG) provide secure, straightforward wiring and reliable connections.
• Voice Coil Diameter: 1.25" (31.7mm) Kapton former — large, heat-tolerant coil supports sustained high-power operation.
• Winding Material: CCAW — copper-clad aluminum winding balances weight and thermal handling.
• Cone/Dust Cap Materials: Paper cone with a paper dust cap — conventional midrange voicing with smooth breakup characteristics.
• Spider/Surround: Cloth surround and 4" spider diameter — supports controlled linear movement and durability.
• Magnet: Ferrite — provides a compact, solid motor for this mid-range driver.
• Overall Dimensions: 6.7" (170mm) diameter, 3" (78mm) depth; 5.87" (149mm) cutout; mounting depth 2.83" (72mm); motor diameter 4.72" (120mm) — compact, installation-friendly sizing for a variety of enclosures.

In a properly designed car-audio system, the 6PRO300MR-4 delivers articulate midrange with high efficiency and low distortion, even at elevated listening levels. The combination of copper demodulating rings and a curvilinear cone enhances linearity and dispersion, while the Kapton-based voice coil and heat-management features support longer sessions without performance loss. This driver is well-suited for professional multi-way setups where precise midrange presence and reliable thermal performance are essential.
