 RCF
TTS28-A
1000 Watt RMS, 2x18 Subwoofer
The RCF TT28-A is a reference double 18" bass reflex subwoofer.
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"
neodymium transducer, the lower power compression. Fiber loaded cone
assembly along with a high excursion triple roll, constant geometry surround.
This combination provides remarkable strength and a peak to peak maximum
excursion of 48 mm. A fully optimized 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 RCF 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 analog
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.
