Turbosound TCS-081C User manual

The TCS-081C is a compact trapezoidal passive two-
way loudspeaker enclosure designed for use in a
wide range of fixed installations.
It consists of an 8” reflex-loaded low
frequency driver and a 1” high frequency
compression driver on a 100°H x 60°V
Converging Elliptical Waveguide™ in an
optimally tuned trapezoidal enclosure. These
high grade components are matched with an
internal passive crossover to ensure a
seamless transition between the HF and LF
drivers.
The crossover incorporates a two-stage
thermal overload protection system which
prevents damage to the high frequency
driver, reacting instantly to large transient
peaks while still allowing wide dynamic
range to be maintained. Although the
protection system is transparent at normal
operating levels, as the level increases the
signal is gradually and imperceptibly
compressed once the critical threshold has
been reached.
The cabinet is constructed from 12mm (1/2”)
birch plywood, screwed and glued together
for maximum rigidity. A powder-coated
perforated steel mesh grille, backed with
reticulated foam, protects the drive units
from damage.
Rigging points are provided on the top,
bottom, sides and rear of the cabinet to
enable the TCS-081C to be suspended and
angled in permanent installations using M10
shoulder eyebolts. The enclosure is also
fitted with internal rigging points for use
with Turbosound and Omnimount™ wall
and ceiling brackets.
A Neutrik Speakon NL4MP speaker
connector and a four-way barrier strip are
located on the rear panel, providing input
and parallel connections to additional TCS
Compact series cabinets.
The TCS-081C is finished as standard in
durable black or white semi-matt textured
paint; raw wood and custom colour options
are also available for decor matching. A
weather-resistant version is optionally
available with an IP rating of 54, enabling
use outdoors and in humid conditions. Line
transformers are optionally available for use
with 70v or 100v line distributed systems.

Impedance A constant current circuit was used to measure the impedance. Frequency response The frequency response
shown was obtained by feeding a swept sine wave through the system in a half space environment. The position of the
microphone was vertically on-axis at a distance of 2 metres, then scaled to represent 1 metre. 2nd & 3rd Harmonic Distortion
Distortion measurements were obtained using an Audio Precision harmonic distortion analysis system and comply with
AES recommendations for enclosure measurement (AES paper ANSI S4-26-1984). Data Conversion All graphs were digitally
generated using the APEX custom software system, designed to translate data derived from Audio Precision ‘System
One’ test equipment into AutoCAD™. This program enables graphical information to be plotted to a high degree of
accuracy.
