Description
All-Weather Performance Without Compromise
The KEF Ventura 4 outdoor speakers are engineered to deliver high-quality sound in even the most demanding environments. Whether installed on a patio, by the pool, or aboard a yacht, this all-weather speaker pair is built to perform reliably through extreme heat, freezing temperatures, humidity, and salt-laden air.
IP65 Certified & Marine-Grade Construction
Independently certified to IP65 standards and salt spray tested for over 1200 hours, the Ventura 4 is designed to thrive outdoors. A weatherproof sealed enclosure, aluminium grille and mounting bracket, plus stainless steel and brass hardware ensure long-term durability in harsh conditions.
Wide Operating Temperature Range
Built for global climates, Ventura 4 operates reliably between -40°C and +70°C (-40°F to +158°F), making it suitable for coastal installations, alpine retreats, and everything in between.
Balanced Two-Way Acoustic Design
The two-way sealed box design pairs a 19mm fluid-cooled aluminium tweeter with a 115mm (4.5″) low-frequency driver. The result is clean, detailed highs and controlled mid-bass performance, delivering clear, engaging sound across outdoor spaces.
Flexible Installation Options
An aluminium mounting bracket with 1/4″-20 threaded inserts provides versatile installation possibilities. The rotatable logo ensures correct orientation whether mounted horizontally or vertically.
