• (1) 8" Shallow Mid-Range Bullet Loudspeaker

The DS18 PRO-X8.4BMSL is an 8 inch shallow mid-range bullet loudspeaker built to deliver strong output where full-depth speakers can’t fit. With a slim mounting depth of only 2.71 inches, it’s ideal for doors, pods, and tight custom installs that still demand loud, aggressive mid-range performance.

Rated at 250 watts RMS and 500 watts max power handling with 95dB sensitivity, this speaker plays loud and clear across an 80Hz to 12kHz frequency range. The integrated aluminum bullet boosts high frequency detail without requiring separate drivers, while the non-pressed cone supports clean vocals and strong attack.

This model is built with a steel basket for stability and durability at high volume, powered by a 21 oz ferrite magnet. A 1.5 inch Kapton voice coil former with CCAW winding helps resist heat and distortion when pushed hard. Recommended high-pass crossover is 120Hz. Grill is not included.
