R212s: R-Series push-pull bass for an ambitious cinema
The R212s brings two 300 mm drivers and push-pull distortion reduction to a more accessible level than the large D models.
It is for systems designed around precision and capacity rather than diameter alone. One unit meets THX Ultra requirements; two achieve the THX Dominus configuration stated by the manufacturer and provide more freedom to create consistent response across the seating area.
Key features
- Two 300 mm woofers with glass-fibre cones
- Push-pull acoustic suspension
- 1300 W amplification
- THX Ultra with one unit; THX Dominus with two
- 600 x 410 x 500 mm; 48.2 kg
- Piano Black
Why the operating principle changes
Unlike the single-driver R18s, R15s and R12s, the R212s uses opposed transducers to suppress even-order harmonics and mechanical reaction. The benefit is greater composure as level rises, not simply twice the output. It belongs in dedicated rooms, at longer listening distances and with soundtracks that make repeated demands.
The R platform explained in full
A 32-bit ARM processor and 48-bit DSP manage protection and filtering. RCA and XLR inputs and outputs, variable phase from 0 to 270 degrees, polarity, low-pass filtering and a 10-band parametric equaliser with three presets are provided. A 2.4-inch touchscreen, iOS/Android app, automatic turn-on and 12 V trigger complete a control system for owner and calibrator alike.
One R212s or two?
One unit already supplies the capacity required by many home cinemas; a second should not be seen only as extra loudness. Placing subwoofers at different points can excite room modes in complementary ways and serve several seats more consistently. Dominus certification with two units makes that design perspective explicit.
The boundary with the D Series
Glass-fibre cones and 1300 W define its R-Series position. The D212s adopts carbon fibre and 3000 W, providing greater reserve for extreme installations. The R212s is for anyone wanting push-pull architecture and full control without the load, cost and scale of an absolute reference room.
