The SoundFrame speakers feature the same driver technology that has made its full-sized speakers such a success, with a couple of twists that account for their slim on-wall profile.
The SF1 units feature a 165mm C-CAM mid/bass driver plus a 102mm IDC mid-range driver with a dual concentric 25mm C-CAM gold-dome tweeter. C-CAM means it’s made from ceramic coated aluminium/magnesium alloy, and the tweeter is gold anodised to a specific thickness to ensure ideal stiffness.
IDC, meanwhile, refers to the Inverted Dual Concentric midrange/tweeter module, which can be pivoted by up to 18° in order to direct the sound towards the listening position – particularly useful when fixed to the wall. Using this module the speakers are a three-way design, and because the module is set as far forward as possible it reduces the amount of diffraction compared with conventional two-way designs.
One final technological note concerns the mid/bass cone, which features Monitor Audio’s RST profile, a radial pattern of surface dimples that improve cone rigidity and reduce distortion, in turn paving the way for lighter and more responsive cones. Both the SF1 and SF2 achieve a frequency response of 55Hz to 35kHz, with 100W power handling.
Inside the R370HD subwoofer’s 18mm MDF cabinet is a 250W Class D amplifier and a downward-firing 10in ultra long throw C-CAM bass driver. On top you’ll find a volume dial and two different EQ preset buttons (optimised for music and video). Placing these frequently-used controls on top is a thoughtful move given that subs are often tucked away in hard to reach places.
There’s a wide range of controls on the back too, including a crossover frequency dial (40 – 120Hz), a low pass filter switch for LFE or stereo input selection and a phase switch, while connections include stereo/LFE RCA inputs and output for those who want to daisy-chain an additional sub.
