The DS18 PRO-HY6.4MSL is a compact, shallow-mount 6.5″ hybrid mid-range loudspeaker that combines a paper-cone woofer with a built-in 1″ titanium compression driver. Engineered for pro-level loudness with precision, it handles up to 300 W peak while maintaining a profile slim enough for tight installations. The inclusion of both ferrite and neodymium magnets ensures a strong motor structure that delivers consistent, powerful sound. This unit comes with a protective grill and is ideal for car audio systems where space is limited, yet high fidelity and volume are required.

Key Benefits

• High Peak Power: 300 W maximum handling gives headroom for loud, dynamic playback.
• Efficient RMS Power: 150 W RMS allows for solid, consistent performance without risking damage.
• Wide Frequency Response: Covers 100 Hz to 20 kHz, giving both clear midrange and high-frequency extension via the built-in driver.
• Shallow Mount Depth: With a mounting depth of only 2.77″ (70.5 mm), it's ideal for vehicles with limited space.
• Balanced Sensitivity: 93 dB (1 W / 1 m) makes it efficient enough to work well with a variety of amplifiers.
• High-Pass Recommended: Use a 140 Hz high-pass crossover to protect the speaker and optimize performance.
• Durable Design: The woofer utilizes a paper cone with a cloth surround, while the 1″ driver uses a titanium diaphragm and a 3″ horn for projection.
• Magnet Structure: Includes both ferrite (woofer) and neodymium (driver) magnets for strength and responsiveness.
• Repair Friendly: Designed to be repairable using the PRO-HY/VC replacement diaphragm.
• Grill Included: Comes with a protective grill to help in rugged or exposed installations.

Installation & Compatibility

The PRO-HY6.4MSL is designed for high-efficiency mid-range performance and fits well in tight spaces, thanks to its shallow profile. Ideal for use in car doors, dashboards, or custom pods, it’s also well-suited for PA-style or pro audio applications. Because of its high sensitivity and efficient design, it's compatible with both aftermarket amplifiers and factory head units (with appropriate crossover settings). Use a high-pass filter of around 140 Hz to protect the speaker and maximize clarity. Mount in a location with stable support, and secure the included grill to protect the diaphragm and horn.
