Overview

Celestion Truvox 0820 8" Midbass Woofer 8 Ohm

Celestion Truvox 0820 8" Midbass Woofer

The Truvox 0820 combines affordability with Celestion’s professional pedigree, offering 500 W continuous power and 96 dB sensitivity—all in a rugged 8″ package. Its pressed steel chassis keeps weight to a minimum (approx. 6.6 lbs), makes installation easier, and places it among the lightest in its class.

The Kevlar‑loaded cone and dual‑roll cloth surround work together to provide clear, high‑fidelity mid‑bass, even at extreme excursion levels—with minimal distortion. A single vent behind the magnet ensures consistent air flow, aiding in cooling and stable performance during extended use.

Designed for easy integration, the 0820 follows industry‑standard mounting dimensions, making it a drop‑in replacement or upgrade for PA cabinets, bass amps, vehicle doors, and recessed wall mounts. With a 2″ copper voice coil and a robust build, the Truvox 0820 delivers clarity, punch, and longevity wherever you install it.
