RCT TT+ Series/TTS28-A subsystem

The
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-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 to peak 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 our 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.
