RCF TTS28-A High Power Sub-Woofer: 2000-W
The TTS28-A is a reference double 18" bass reflex subwoofer. It is ideal for touring applications. With the digital switching amplifiers, neodymium woofers and a well-designed structure, it is one of the smallest and lightest double 18" systems available. A unique feature is the semi-charged horn design, which at low frequencies around 40Hz operates as a conventional bass reflex cabinet, however at the slightly higher frequencies in the 80 to 100Hz area the system operates as a ‘semi charged horn loaded’ design, which provides around 3 to 4dB more efficiency.
Superior Woofers
RCF LF18N401: incredibly linear frequency response characteristics, the highest power handling of any comparable 18-inch neodymium transducer, the lower power compression. Fibre loaded cone assembly along with a high excursion triple roll, constant geometry surround. This combination provides remarkable strength and a peak-topeak maximum excursion of 48 mm. A fully optimised T-pole design generate the minimum amount of flux modulation, the unique dual forced air venting system guarantee a very efficient voice coil ventilation for minimum power compression and higher power handling. Massive power: On the subwoofers each single transducer is independently driven from a 1 kilowatt RMS amplifier providing an incredible performance and amount of sound power from a very compact size.
Flexible Controls
Power amplifiers are driven from a very accurate analogue input board: perfect linearity and audio quality, soft peak limiter, RMS limiter. Many crossovers and operation options are available: extreme low frequency high pass, phase inversion, 80 Hz and 110 Hz crossover, adding mode crossover for maximum punch of the system.

TT+ SERIES High Power Woofers
Powerful Tools for Powerful Systems
Sound systems designed for almost any application benefit from the addition of extended low frequency or sub bass. True natural reproduction of music requires that the sound system’s output should extend into the lowest octaves of the audible spectrum. Whether it is for the provision of subtle dynamic sound for theatre applications, the raw power of a ‘bass drum kick’ or an air moving concert sound sub bass system – RCF has the solution.
