The tweeter radiates as much backwards as forwards. Behind it, a metamaterial disc pierced with channels of differing lengths traps that rear wave and dissipates it as heat: 99% of the high-frequency energy never comes back to the cone. What is left is the signal.
142 mm of depth: the Q4 fixes to the wall without advancing into the room. The cabinet stays bass-reflex despite that constraint, and the bass reaches down to 52 Hz at −6 dB. The crossover falls at 1.8 kHz, lower than on the other Q Meta.
The 25 mm tweeter occupies the centre of the 130 mm aluminium cone. On an on-wall speaker that point counts double: hung high up, it rarely plays on the axis of the ear, and a single source holds the image when both ways leave from the same place.
400 × 250 mm for 5.7 kg — the dimensions of a medium-sized painting, the weight of a dictionary. It calls for 10 to 150 W into 4 Ω, minimum 3.2 Ω. Three finishes follow the range: satin black, satin white, walnut.
