ConTour Array™ 1.4

Design and Construction 

The CTA 208 Mid/High unit‘s top and bottom 
panels slope at an angle of 4.5°. Water-repellent, 
black PU lacquer coats the enclosure made of 
18 mm, 13-ply birch plywood. Your choices of array 
curving angles (or splay) are 0°, 3°, 6° and 9°. 
The baffle board cover consists of a metal grille; 
found behind it are two CD horns equipped with 
acoustical lens for the four 1" drivers. 

The CTA 208 weighs 29 kg. It is 51 cm wide, 
52.5 cm high and 34.6 cm deep (including rigging 
attachments). Two grips on the side panels simplify 
transport and set-up.

Fully integrated rigging attachments comprising 
three quick-release pins and three rigging 
connectors, two mounted on the sides and one in 
the rear, serve to fly the mid/high units.

Electrical and Acoustical Data

The CTA 208 enclosure features two 8" cone chassis 
speakers and four 1" B&C high frequency drivers 
with a front-mounted acoustical lens in a CD horn 
configuration. An internal passive crossover with a 
crossover frequency of 2 kHz addresses the drivers 
via a special acoustic lens. The CTA 208 enclosure‘s 
nominal electrical power-handling is 500 watts 
RMS at 8 ohms impedance. It produces 105 dB 
(1W@1m) sound pressure, measured under half-
space conditions. Maximum SPL measured under 
the same conditions at one meter is 134 dB at 10% 
THD. The CTA 208 radiates at a horizontal angle of 
100°. Frequency response ranges from 95 Hz to 
19 kHz (±3 dB).

Connections

The ports are out of harm‘s way on a recessed 
connector panel on the CTA 208‘s back. It offers 
two Speakon

®

 NL 4 connectors. Pin assignments 

are pin 1+ = mid/high +, 1– = mid/high-.
Caution: Please connect just one CT 208 to each 
CTA 118 Sub enclosure. The second port serves to 
connect a power amp in parallel (up to two CTA 208 
at 4 ohms).

1.1 Specifications, CTA 208

A professional two-way system featuring cylindrical 
wave technology, this cabinet serves to set up 
vertical line arrays and project a coherent wavefront 
across the entire frequency range. The precision-
tuned enclosure sports two 8" midrange speakers. 
Four 1" high-frequency drivers address two constant 
directivity horns with 100° horizontal directivity via 
a special acoustic lens. Vertical directivity depends 
on the number of CTA 208s in use.

The housing is made of 15/18 mm birch plywood 
coated with black PU varnish. Its fully integrated 
rigging hardware adjusts to four 0°, 3°,6° and 9° 
angles for setting up line arrays. An integrated 
pole mount offers two tilt angles of 3° and 11°. An 
impact-resistant steel grille covers the front.

The active CTA 118 Sub system subwoofer with 
an integrated DDO-Pro™ Controller drives the 
enclosure. CTA 208‘s frequency response (+/- 3 dB) 
ranges from 95 hertz to 19 kHz.  Axial sensitivity is 
105 dB, measured under half-space conditions at @ 
1W / 1m. Maximum SPL measured under the same 
conditions with two CTA 208s is 134 dB at 10% 
THD. Each unit‘s nominal power handling is 
500 watts RMS at 8 ohms.
