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 returns to the cone. What is left is the signal.
Four 130 mm cones frame the Uni-Q, two on each side. That symmetry holds the image when you move off axis — the classic failing of horizontal centre speakers, where two bass drivers either side blur the voices. Crossovers at 500 Hz and 2.4 kHz.
The cabinet is sealed: inside a closed unit, a port blows against a panel and colours the lower midrange. The R6 Meta does without one and starts at 52 Hz at −6 dB. It reaches 111 dB, enough to hold a soundtrack without compression.
625 mm wide for 17.8 kg: the R6 Meta is the flagship centre speaker of the R range and calls for furniture to match. It takes up to 250 W into 4 Ω, 3.2 Ω minimum, and returns 88 dB. Three finishes: gloss black, gloss white, walnut.
