2.1. Product description

The 16C is a passive 2-way column loudspeaker housing four 4”

neodymium drivers and a 0.75” compression driver mounted on a

CD horn.

In the vertical plane, the cabinet provides directivity control down

to 500 Hz.

The HF horn has a nominal dispersion of 90° x 40° (h x v).

The 4" drivers are arranged in a unique cardioid setup radiating

through waveguide elements at the front and damped ports at the

rear of the cabinet. This design provides a cardioid dispersion

pattern with an average broadband attenuation to the rear of

approx. 18 dB.

The loudspeaker cabinets are based on an extruded aluminum

profile with a metal grill protecting the front of the loudspeaker.

Two continuous rails (8 mm, T-slot profiles) are provided at the rear

for attaching a wall mount bracket.

2.1.1. Cardioid dispersion

Due to their dimensions, conventional column loudspeakers

provide no significant horizontal directivity below 2 kHz.

At low and mid frequencies, the resulting polar pattern is almost

omni-directional (dotted line).

The cardioid patterns of the 16C show a much higher directivity

resulting in much less energy radiated into the room (continuous

line).

Typically, column loudspeakers are mounted onto walls or other

hard plane surfaces. Hard surfaces act as an acoustic mirror. That

means, the room is not only covered by the sound of the actual

column loudspeaker but also by the sound produced by its virtual

mirror source from "behind".

In the case of conventional column loudspeakers with their low

horizontal directivity, the mirror source radiates at a similar level as

the loudspeaker itself.

The combination of both sources results in a dipolar characteristic

where the main energy is radiated along the walls (dotted line).

The 16C, however, with its cardioid dispersion pattern provides an

even dispersion characteristic and a useful directivity when

mounted onto a wall.

2.1.1.1. Flush mounting

If architecturally required, xC-Series cabinets may be partially flush

mounted.

Please note that this will render the cardioid ports ineffective and

as a result, may change the dispersion pattern.
