Aura Blu 308 X
8” Linear Coaxial Speaker
Product at a Glance
The British Acoustics outdoor Aura Blu 308 X is designed to withstand harsh environmental conditions with dust, splash, and UV resistance. Built around our signature ultra-low distortion woofer, it delivers clean and extended low-frequency performance, ideal for enhancing bass response in outdoor installations. Engineered for durability, the enclosure features sealed terminals and a double dura-coated grille, making it suitable even for coastal applications. This speaker provides system designers with a reliable LF extension solution that maintains sonic integrity while enduring the elements. Whether for resorts, patios, or open-air venues, it ensures consistent performance and long-term reliability in challenging conditions.
CRAFTSMANSHIP
Painstakingly Perfect Production
Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
