8" Mid-Range Loudspeaker With Bullet 275W RMS 4-Ohm
The PRO-X8.4BM is an 8" mid-range loudspeaker that delivers 275W RMS and 550W MAX power, giving your build raw, punchy sound with pro-level clarity.
Bullet Dust Cap. Bigger Sound.
A high-efficiency bullet-style aluminum dust cap helps project sound further and sharper, giving you hard-hitting midrange your system craves. Its steel basket not only reinforces strength but looks as bold as it sounds.
Push It To The Limit
With a 1.5" 4-ohm voice coil wound on a Kapton former, this speaker handles serious heat. Pair that with a 97 dB sensitivity and you’ve got volume that stays clean — no distortion, no drop-off.
Tuned for Tight Installs. Ready for Power.
The PRO-X8.4BM fits flush with a 3.2" mounting depth and packs a 30 oz ferrite magnet to drive performance and reliability. Covering 115Hz–16KHz, it captures the full midrange with precision and power.
Power up with the PRO-X8.4BM — the midrange monster that’s always LOUD, always CLEAN, and always DS18.
