The RCF ST 12-SMA is a multi-purpose active loudspeaker, designed to be the everyday monitoring tool for rental companies and professional musicians.

With its ultra compact design together with high output levels, ST 12-SMA is the answer to a wide variety of production requirements. It is particularly effective for small bands and personal use; a key requirement for everyday audio systems, delivering simple ‘plug and play’ solutions, without compromising performance and portability.

Stage Monitor
Use it as a stage monitor. The “FLAT” equalization mode is set for monitoring applications, when the system is placed on the floor.

With an easy 90° rotation and a simple click on the FLAT/BOOST switch, the ST 12-SMA turns into a loudspeaker, with the equalization settings in “BOOST” mode.

At A Glance:
  • 800 Watt Peak, 400 Wat RMS
  • 129 dB max SPL
  • 45 Hz - 20 kHz frequency response
  • 12" Woofer, 2.5" voice coil
  • 1" Driver, 1.4" voice coil

Perfectly Flat Response Curve
This turns into a maximum rejection to positive feedback between the stage monitor and the microphone, ensuring immunity from the Larsen effect (microphone-mixer-monitor chain) for an enhanced freedom of movement during live performances

Accurate & Powerful Woofer
ST 12-SMA features a professional 12’’ high power woofer, 2.5’’ voice coil, delivering extremely accurate punchy bass and precise low frequency control, making it an ideal stage monitor/speaker for personal use and small bands.

High-Fidelity Driver
The custom-made compression driver ensures a transparent midrange and extreme accuracy. It features a high performance 1-inch exit throat and 1.4’’ voice coil, with a frequency range up to 20 kHz. A particularly resistant kind of polyimide is used for the diaphragm and suspension, in order to increase the driver’s mechanical strenght and stability.

ST Series two-way speakers are equipped with a new generation digital amplifier, resulting in very high output, extremely low distortion and an incredibly natural sound. The limited weight of our digital amplifier facilitates transportation and thus ensures maximum usability on the road.

Each amplifier presents both XLR and jack inputs, XLR output link, volume, EQ Mode (FLAT/BOOST), MIC/LINE sensitivity switch & VDE input connector. It features a solid mechanical aluminium structure which not only increases the amplifier’s stability during transportation, but also helps in heat dissipation.

Two sides show a distinctive inward curve. The reason behind this original design choice is related to sound optimisation. In a cabinet with a standard design, sound waves reflect on the cabinet’s edges, thus creating undesired effects of absorption and disturbance or decreasing sound coverage. In our ST Series sound waves don’t hit the sides because of the slightly concave profile with moulded edges that helps avoiding all acoustical drawbacks.

Instead of being simply flat, the grille shows a distinctive design with 3 sides. This arch-inspired structure adds resistance to the whole system, creating a more balanced distribution of forces when the stage monitor is subject to stress and pressure, as often occurs during tours and live performances
