DALI SONIK ON WALL speaker, 123 mm deep, integrated wall bracket, a 5.25-inch Clarity Cone driver and a 29 mm tweeter. Sold individually.

The SONIK ON WALL projects only 123 mm once mounted, for 385 mm of height and 245 mm of width. DALI recommends 0 to 10 cm of clearance, so it sits flat against the partition. This is the format that frames a wall-mounted television without protruding into the room.
The bracket is built into the cabinet, so there is no separate mount to buy or adjust. The speaker mounts horizontally or vertically, and the grille follows the chosen orientation. The terminal takes a single cable, which limits what has to run inside the wall.
The 5.25-inch Clarity Cone driver and the 29 mm soft dome cover 55 Hz to 26 kHz at plus or minus 3 dB, with bass reflex tuning at 50 Hz. The two-way crossover sits at 2400 Hz. Against a wall the bass gains a few decibels, which offsets the cabinet size.
White, black ash, natural oak and walnut match the SONIK floorstanders. DALI rates the speaker for LCRS duty, so front, centre or side. Its 87 dB sensitivity at 6 ohms takes 25 to 100 W.
