The DALI OBERON ON-WALL is a slim, discreet and surprisingly powerful on-wall speaker, which utilizes DALI's unique on-wall bass port system. It houses an oversized 29 mm ultra-lightweight soft dome tweeter together with a 5.25" SMC based wood fibre woofer and the unique down-firing bass port system, which DALI has perfected. It combines technologies which make it possible to create a speaker that - despite its compact size - will render audio like a much larger model. For this reason, it's the perfect choice for both stereo and surround setups.
