CBT36K Assembly Manual
1. THE PRELIMINARIES:
INTRODUCING the CBT36:
The CBT36 is a floor-standing
5ft.-tall two-way curved line
array that provides sonic
accuracy and sound-field
coverage that surpasses even
the finest high-end
loudspeakers.
The system not only provides
extremely even coverage at all
points up-down, right-left, and
near-far; but is linear-phase
and time-aligned at all these
points also!
Based upon declassified
military research on Constant
Beamwidth Transducers
(CBT) originated by the U.S.
Navy, and a series of technical
papers by Don Keele, the
system was designed by
Marshall Kay and Don Keele
.
Each array features 18 Dayton
Audio 3.5” ND Series drivers
with 72 specially designed ½”
aluminum-dome tweeters, and
is available assembled or in kit
form. The CBT36 will redefine
your expectations of audio
reproduction system
performance.

This manual describes the assembly process of
the
CBT36K curved-arc high-end loudspeaker array
sold by electronic supplier Parts Express. It includes many sections to aid in the assembly
procedure. Two appendices are provided at the end of this manual: the first gives a detailed
description of the CBT36 along with a set of specifications, and the second fully describes the theory of
operation behind CBT loudspeaker arrays and how it applies to the design of the CBT36 and includes a
CBT bibliography.
When you first view this manual for the CBT36K, the assembly process looks very imposing, complicated
and difficult! But first looks can be deceiving. We have done all we can to simplify the assembly process
by spelling out the procedure in great detail and documenting all steps with high-resolution photos to
guide you through the process.
Although the manual is quite large, it’s jam-packed with useful information. With the comprehensive
information provided in this manual, the CBT36 has to be the most documented high-end loudspeaker
that has ever been sold! There are absolutely no secrets here!
