Q 15-P is a two-way, bi-amp point source module for mid-distance and long-throw applications, combining a compact size with very high output and accurate speech and music reproduction. The system is equipped with the latest generation of RCF precision transducers featuring one 15" neodymium woofer and a 4" titanium-neodymium compression driver for a total of 1500 W power rating and 40° (vertical) and 22.5° (horizontal) directivity. The enclosure shape is trapezoidal and offers a 22.5° coupling angle on each side. Q series typical applications span from point-source configurations for mid-distance applications to clusters up to 8 modules for long-throw applications. The grille is epoxy-coated, with a woven fabric backing for dust protection. The cabinet is made of multi-ply Baltic birch plywood with a highly resistant, textured, black polyurea finishing and features two rear-panel Neutrik Speakon NL4 connections for bi-amplification (4 poles)

Constant curvature advantage

Delivering extraordinary clarity and power handling, the Q Series modules feature best in class flexibility for multiple applications. Due to its sleek form factor, the speaker is unobtrusive and preferred when space is a constraint. Component positioning of the Q Series and the ability to rotate the cabinet in any position, ensure precise directivity and a detailed sound image, reducing spots of break up or attenuation. RCF developed the Q Series for fixed installations requiring remarkable coverage and coherence in a premium yet discrete look. Despite their dimensions, Q Series speakers are built upon RCF’s premium concert-proven technologies for optimum power-to-size ratio able to cover large areas.

Legendary transducers

The RCF Q Series features state-of-the-art RCF transducers with neodymium magnets. RCF’s experienced engineering teams have developed and matched each component. A set of protections preserve product life and reliability.
Low frequencies
  • 15" neodymium woofer, 4.0" v.c.
  • Water-resistant fiber doped cone
  • Polycotton M-roll surround
  • Hypervented magnetic structure
High frequencies
The ND940 Compression Driver in pure Titanium with a 4 inches voice coil works from 600 Hz. This allows a better impulse response, fast decay, translating in perfect vocal clarity and enhanced quality in mid-frequency — leaving the woofer to manage the lower part of the spectrum. Lightweight and powerful, RCF neodymium drivers are a reference in performance and reliability.
The speaker can only be powered by two amplifiers, one for each transducer (4 poles via NL4 connector).

Constant reliability

The Q Series speaker is carefully engineered to pack maximum output and superb sound quality with minimum size. The cabinet is made of high-quality water-resistant Baltic birch plywood with internal structural metal bracings, rigid and resonance-free. A special polyurea paint creates a very thick coating of the cabinet, making the speaker highly resistant to scratches, bumps, sun, and extreme weather conditions. The heavy-duty front grille is powder coated. A transparent-to-sound foam backing on the inside of the grille helps to further protect the transducers from dust.

Use anywhere attitude

Q Series speakers can be deployed either horizontally or vertically, with a coverage angle proportionally equal to the sum of the enclosures in the array (22.5° x n). The cabinet features multiple M10 suspension points on both sides. Optional rigging accessories include two fly-bars for horizontal (up to 4) and vertical placement (up to 6 with a single flybar, or 8 with double flybar), stainless steel plates for rigging, and -10 degree spacing to decrease the coverage angle for long-throw applications. All rigging is made of high-strength structural steel with a high safety factor. The compactness and lightweight of the system, combined with top of class suspension system, guarantee a fast and secure hanging procedure.
