|The QR36 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.
As an “array of line-sources”, a QR system acts as true
cylindrical radiator, offering a 3dB SPL drop-off per doubling
of distance (in the “near-field” or “Fresnel-zone”). This
brings significant advantages in SPL coverage and (intelligibility)
throw, from a relatively simple system.
Featuring double RBN1801 pro-ribbon drivers
(patents pending), the QR36 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 “gainbefore-
feedback” up to directly in front of / under the
The Signal Integrity Sensing™ pre-wiring ensures
complete cable/connector compensation between
the QR36 and ALC. In this way, the ALC can be
loaded down to 2 ohms, without any sacrifice on
response quality (2 units QR36 parallel on one
channel loads 3 ohms).
