EDISON, NJ — The new Sigma Series of loudspeakers from dB Technologies represents the latest technology in the summation of sound with a system approach. Musicians and DJs who provide their own backline are looking for high performance, reliable, high SPL, portable systems that set up quickly and can be easily tweaked without a lot of fuss. The Sigma Series provides just that.
More details from RCF (www.rcf-usa):
The Sigma Series features new custom speaker components designed exclusively for the series by RCF, as well as the latest generation of DSPs and dB Technologies Digipro power amplifiers. The series features three cabinets which can be used by themselves, or stacked or pole mounted to create the size system necessary for the venue.
Included in the Sigma Series are the S115 15” 2-way active speaker, S215 double 15” quasi 3-way active speaker and S118 18” subwoofer.
Let’s take a closer look at each one:

Frequency response 46 Hz-20 kHz (+/- 10 dB). New generation 1000W RMS Digipro G2 amplifier. 133 dB max SPL
S215 – Dual 15” quasi 3-way active system. Many venues demand high SPL and low frequency response. This full range system provides just that in a single cabinet. Loaded with dual 15” phase-plugged woofers with 3” voice coils, coupled with a 1.4” titanium compression driver with 2.8” voice coil on a 60×40 CD horn waveguide this system is designed to handle considerable loads. Frequency response 42 Hz-20 kHz (+/- 10 dB). New generation 1400 watt RMS Digipro G2 amplifier, this speaker achieves 139 dB max SPL.

The Sigma Series features 24-bit/48 kHz DSP with system presets (flat, boost) and limiter (dual active peak, RMS, thermal). The Digipro G2 power amp modules are rated at more than 90% efficient and designed to ensures that the output of the cabinets remains even and transparent.
Unique to this series is the H.E.T. cabinet housing. Remarkably rugged, the housings are made of premium quality multiply wood with a hardwearing, durable and scratch-resistant coating. Rugged plastic side panels provide excellent protection for the housing as well as integrated grips for transport. The cabinets are also designed so they can be easily stacked, or offer pole mount option.
