Modular 2-Way Column Loudspeaker to be Used as Vertical Array
Series: Q-Series
Model: QR18
- RBN1801 pro-ribbon HF drivers with exceptional intelligibility and high SPL output
- All Neodymium drivers for excellent performance-to-weight ratio
- Modular scalable array system, with multiple units flown or stacked above each other
- SIS pre-wired for very high damping and further reduced distortion (with ALC)
- Extended headroom/SPL and protection in combination with SDP modules (with ALC)
The QR18 is a modular 2-way column loudspeaker to be used as vertical array, either in stacked or flown configuration, for both permanent and (limited) portable installations. It combines the ease-of-use handling of a conventional system, with the throw of a line-array system. Featuring a single RBN1801 pro-ribbon driver (patents pending), the QR18 offers Real-90 horizontal dispersion with seamless coverage; Its transient response and high peak power handling enable an amazing intelligibility and throw. The 91% active frontal radiation, in combination with the ribbon’s all-natural cylindrical flat (Isophasic) wavefront, brings maximum “gain-before-feedback” up to directly in front of / under the cabinet. The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the QR18 and ALC. In this way, the ALC can be loaded down to 2 ohms, without any sacrifice on response quality (4 units QR18 parallel on one channel loads 3 ohms). The system includes dedicated filtering, but system equalizing is done remotely (electronically) fully utilizing the individual speaker components’ power capacity; In combination with the unusual high peak power handling (3000W/200mS), this results in a virtually infinite headroom SPL from 1kHz. up. Typical applications for the QR-systems include main system for theatre, PA system in “acoustically challenging rooms”, as well as high power side-fill stage monitoring. For full system performance, the QR18 needs to be driven by an ALC controller-amplifier. Driven by the ALC, the QR18 delivers maximum sound quality with inaudible (power and excursion) protection (SDP circuit).
