Product Images

The JB4 MKII is JohnBlue Audio's top of the line bookshelf fullrange speakers. Its enclosure is crafted using 24mm thick highpressured bonded MDF. Thanks to its proprietary internal honeycomb structure, NO fibre is needed internally for damping. This allows for an extremely transparent delivery. Innovative enclosure design allows the driver to radiate sound from the enclosure edge and give it a horn effect. Musical and clean, with a tight punchy bottom end, JB4 MKII have an uncanny ability to“disappear”and easily rivals the LS3/5A.

Like the Flagship JB8, Each pair of JB4 MKII is fully laminated with SOLID cherry wood veneer and handbuffed to a achieved a low sheen subtle shine.
