According to RSF, the design philosophy for the RCF TT+ Series is based on offering the sound engineer solutions with the ability to provide controlled and consistent sound definition at high output levels for applications ranging from concert halls and houses of worship to touring and stadium situations. The strength of the product is based on the fact that RCF is one of the few loudspeaker manufacturers worldwide who completely design and manufacture the transducers, cabinets, amplification and control electronics. This control allows RCF to offer the TT+ Series offering maximum output efficiency in sound pressure levels, minimum mechanical weight ratio and extremely compact dimensions of the products.
The process starts with the transducers. The RCF design features lightweight neodymium magnet, inside-outside cooper voice coil and dual-forced hyperventing system for heat dissipation, dual silicone spider which provides strength and stability under large excursion conditions for tight response and water treated cone for weather and high humidity environment protection.
The success of the RCF TT+ Series has relied on providing total system design capabilities. Complementing the line array products, RCF has offered the TTS26-A dual 15” subwoofer, TTS36-A dual 18” subwoofer and TTS56-A dual 21” subwoofer.
Now RCF expands the low frequency offerings with the TTS15-A single 15” and TTS18-A MK2 single 18” products. The 15” woofer is powered by an onboard 1100-watt RMS Class-D amplifier with a frequency response from 40-400 Hz and 134 dB SPL maximum output. The TTS18-A MK2 is an upgrade to the original TTS18-A with new amplifier and transducer technology. This enabled RCF to increase the power by 40 percent to 1400-watts with frequency response down to 35Hz and ability to achieve 136 dB max SPL. The transducer is an 18” hypervented woofer with 4” voice coil.
RCF’s propriety RDNet onboard allows for integration in total system design as well as the abiity to remote monitor all components in the cabinet with DSP to incorporate into system audio control functionality.
The design of the subwoofer cabinets allow them to be positioned vertically or horizontally, with M20 pole receptacles on both top and side. The cabinets are heavy duty multi-ply birch with weatherproof finish. For transport, RCF offers an optional detachable front wheelboard with 100-millimeter casters.
