dBTechnologies has introduced the Sigma Series of loudspeakers, incorporating new custom components designed exclusively for the series by RCF, as well as the latest generation of DSP and the company’s Digipro power amplifiers.
The series includes three cabinets which can be used by themselves, or stacked or pole mounted to create the size system necessary for the venue.
Models include the S115 single 15-inch, 2-way active model, S215 dual 15-inch, quasi 3-way, and the S118 single 18-inch subwoofer.
The 24-bit/48kHz DSP offers system presets (flat, boost) and limiter (dual active peak, RMS, thermal), while the Digipro G2 power amp module is rated at more than 90 percent efficient and designed to ensure that the output of the cabinets remain even and transparent.
S115 – The 15-inch woofer with 3-inch voice coil couples with a 1.4-inch high-frequency titanium compression driver with 2.8-inch voice coil on a 60- x 40 degree CD horn waveguide. The G2 amplifier delivers 1 00 watts (RMS). Frequency response is 46Hz to 20kHz (+/- 10 dB) and max SPL is rated as 133dB.
S215 – The dual 15-inch phase-plugged woofers have 3-inch voice coils, coupled with a 1.4-inch titanium compression driver with 2.8-inch voice coil on a 60- x 40 degree CD horn waveguide. The G2 amplifier provides 1 400 watts. Frequency response is 42Hz—20kHz (+/- 10dB) and max SPL is rated as 139dB.
S118 – The 18-inch woofer has a 4-inch voice coil. The G2 amplifier delivers 1 400 watts. Frequency response is 32Hz—110Hz, with switchable crossover at 80Hz and 100Hz, and max SPL is rated as 134dB.
