DS18 8PRO300MB-4 8" Mid-Bass Loudspeaker 300 Watts 4-Ohm (each)

The DS18 8PRO300MB-4 is an 8-inch mid-bass loudspeaker built for car audio enthusiasts who need controlled, high-output mid-bass in pro audio or competition systems.

• Nominal Diameter: 8 inches / 203 mm, sized for common door or custom enclosure applications while maintaining focused mid-bass projection.
• Power Handling: 150 W RMS and 300 W maximum, paired with a 1.5-inch CCAW voice coil on a Kapton former for sustained output without thermal compression.
• Sensitivity: 97 dB (1 W / 1 m), providing high acoustic output from moderate amplifier power in typical vehicle installs.
• Frequency Response: 60 Hz–5 kHz with an 80 Hz recommended high-pass crossover, delivering clean mid-bass down to the crossover point while integrating smoothly with subwoofers.
• Impedance: 4 ohm nominal, allowing straightforward wiring into most multi-channel or bridged amplifier configurations.
• Motor Assembly: 20 oz ferrite magnet with steel basket in satin black finish, yielding a 0.48 L displacement volume for compact box designs.
• Thiele-Small Parameters: Qts 0.34, Vas 16.4 L, Fs 85 Hz, Xmax 9.8 mm, supporting sealed or vented alignments that emphasize punch and transient response.

This speaker suits dedicated mid-bass arrays or three-way front stages where vocal clarity and impact must remain distortion-free at high SPL levels. Its single-unit packaging and 3.6-inch mounting depth simplify retrofits into doors or custom pods without requiring major fabrication changes.
