8” Sealed Back Mid-Range Loudspeaker
DS18’s PRO-X8MSE is your go-to 8" mid-range speaker when you need serious sound! With a sealed back design, this speaker thrives in high-pressure enclosures like door panels or chucheros, delivering consistent performance in tough environments.
Built to Handle the Heat
This 8-ohm loudspeaker pushes 275W RMS and 550W MAX power, supported by a 1.5" Kapton voice coil and ferrite magnet for efficient heat dissipation. With a 97dB sensitivity and wide 250Hz–8KHz frequency response, the PRO-X8MSE offers crisp, distortion-free mids that cut through any mix.
Designed for Tight Installs
Perfect for wall builds, doors, or high-intensity chuchero setups—this speaker’s sealed back means you don't need a custom enclosure to get insane performance. With a compact 3.54" mounting depth, installation is easy and versatile.
