Product Overview

PRO-X8.4BM

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.

Saddlebag Speakers

I bought these along with the 24+ Harley lid kits. Speakers are fantastic. You’re not going to find a speaker with this clarity and volume for less than twice the price.

PRO-ZT 6x9" Coaxial Mid-Range Loudspeaker with Water-Resistant Cone Built-in Bullet Tweeter and Grill | 275W RMS 4-Ohm

Performs as expected

Working as described, have the amplifier gain set to half to power the ds-18 jeep soundbar and dash speakers. Much happier now since it is all amplified.
