TTS28-A High Power Subwoofer

The TTS28-A is a reference double 18" bass reflex subwoofer,

TTS28-A Active High Power 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-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 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.
