TTS 15-A


The RCF TTS 15-A is a compact, high output subwoofer module that is ideal in combination with TT+ two way touring systems. The RCF TTS 15-A features low weight for easy handling, weatherproof cabinet, a 15” woofer powered by a 1100 watt RMS SMPS class-D Amplifier with full DSP and RDNet network capabilities.

The amplifier integrates a low-noise 32 bit DSP circuit, controlled through the RCF exclusive RDNet network to easily handle the soft clipping limiters, RMS limits, polarity, amplitude, timing and equalisation. All the settings, monitoring and advanced features are available inside the integrated RDNet Networked Management software. The available encoder on the back adjusts volume, delay and presets.

The RCF TT+ cabinets are made of high-quality birch plywood with weatherproof treatments. The subs are stackable and light-weight, for an easy set-up and tear down. The polyurea coating and the rugged structure of the cabinet survive long-term use and transportation and the separate housing for the amplifier guarantee the best components efficiency and reliability. A pole receptacle on top and side allows the use of the woofer in various configurations. The transportation is fast with the detachable Kart kit: a dolly caster-board with rugged tour grade casters and rotating cam mechanism.

RCF manufactures these components to deliver the cleanest, punchiest, and undistorted low frequencies reproduction. In order to dissipate the heat generated by the powerful voice coil, RCF engineers have developed a unique internal ventilation system with very low power compression. The Hyper Ventilation System is the result of a complex combination of ventilation ducts in the voice coil former, in the magnetic structure and in the woofer’s basket. Both the cones are water resistant.
