Alcons Audio USA QR36 pro-ribbon line-source column

The Q-series scalable pro-ribbon-array columns can popularly be seen as a “cross-over product” of a traditional point-source loudspeaker and a J-curved line-array system. The QR36 has been designed as solution to obtain excellent coverage and ultimate intelligibility over longer distances in “acoustically challenging” environments, with high SPL full-range HiFi sound quality from a relative simple system.

The QR36 is a two-way passive-filtered modular line-source column. With a length of one (1) meter/39-in, the QR36 consists of 6x 6.5” woofers in frontal bass reflex-loading and 2 units of Alcons’ RBN1801 18-in pro-ribbon transducers with patented “Real-90” horizontal dispersion. The frequency response is 74Hz - 20kHz.(+/-3dB). The extreme peak power handling of the 2 RBN1801 pro-ribbons of 6000W (!) from 1kHz. up, offers a 150dB “virtually infinite headroom”. As an “array of line-sources” and with an unprecedented active frontal radiation of more than 92%, a QR system acts as true cylindrical radiator, resulting in a very sharply defined vertical projection without any significant side-lobes above and below the array. This prevents ceiling reflections, offers unusually high"gain-before-feedback” and brings line-array SPL coverage and (intelligibility) throw. When used in multiples up to 10m/33ft, the QR’s form a continuous line-source, extending the “near field” of the system over longer distance and lower frequencies.

- Modular scalable line-source array system, ideal for acoustically challenging rooms.
- Line-array SPL coverage and throw from a relatively simple system.
- 18-in pro-ribbon HF drivers with exceptional intelligibility and very high SPL output.
- Unusual sharply defined vertical projection and very even horizontal dispersion.
- All Neodymium drivers for excellent performance-to-weight ratio.
- SIS pre-wired for very high damping (10.000) and further reduced distortion (with ALC).
- Passive filtering for easy operation and economical powering.
- Full-range, high-SPL HiFi sound quality alternative solution to beam steering systems.
