ELAC Debut 3.0 DB63 (B6.3) – Bookshelf Speakers
The ELAC Debut 3.0 DB63, commonly referred to as the Debut B6.3, is a 2-way bass-reflex bookshelf speaker designed for high-quality stereo and home cinema applications. Building on the previous DB62, it combines a newly developed 6.5-inch aramid-fibre woofer with a custom 1-inch aluminium dome tweeter, refined cabinet construction and dual-flared bass-reflex porting for detailed highs, natural midrange and controlled low-frequency performance.
Key Features
