Overview

Beyma 15WR400 WR Series 15" Subwoofer 8 Ohm

15WR400 WR Series 15" Subwoofer 8 Ohm

Though termed a low-/mid‑frequency driver, the 15WR400 covers an extensive bandwidth from 40 Hz up to 4 kHz—giving it the versatility to serve both bass and lower mid‑frequency roles in sound systems. With 400 W AES power rating and 99 dB sensitivity, it achieves high output without needing excessively high amplifier power. The 3″ copper voice coil and FEA‑optimized magnet structure combine for strong thermal management and sonic clarity. The ±6.3 mm Xmax and 30 mm excursion before damage ensure the driver can handle dynamic signals without risk of mechanical overload. Weather‑treated components add reliability for long sessions and varied environments. The 15WR400 is well‑suited for compact reflex or bass/mid‑bass cabinets seeking high efficiency and controlled output.
