Overview

Beyma 10G40 G40 Series 10" Subwoofer 8 Ohm

10G40 G40 Series 10" Subwoofer 8 Ohm

The 10G40's 400 W AES power handling ensures it can manage substantial input levels, providing reliable performance in demanding audio environments. Its sensitivity of 95 dB (1W/1m) allows for efficient conversion of electrical signals into clear and dynamic sound output. The 3" copper voice coil, constructed with a polyimide fiberglass former, enhances thermal stability and durability, contributing to consistent performance over time. The transducer's extended controlled displacement, with an Xmax of ±7 mm, allows for greater cone movement, enabling the driver to produce deeper bass frequencies without distortion. With a peak-to-peak excursion before damage of 28 mm, the 10G40 can handle significant mechanical stress, ensuring longevity even under high-demand conditions. Specifically designed for woofer applications, this transducer excels in delivering low-frequency sound reproduction with clarity and depth. Its optimization for small bass-reflex cabinets makes it an ideal choice for compact audio systems where space is limited but high-quality bass performance is still demanded. ​
