Once he
had picked the driver, he went on a search of the Net to
find a
suitable cabinet. After days of looking at and discussing possible
cabinets,
he decided on the Singular, unfortunately the site that had
that info
is no longer available. But some info from that site was copied, and follows.
Simplicity, easy to built and very
good balanced in combination with drivers having a Qts
between 0.3 and 0.6 from which you
can choose. If you like your FE206E's in a reflex
then you will love them in the SINGULAR
for its more efficient loading over a wider range.
If you like your Lowther driver
in a reflex then you will love them in the
SINGULAR even more...
The basic design for this system
was initiated by Onur Ilkorur for his AER drive units,
providing a pretty efficient loading
over a wide range. The system is not a Bass Reflex
which is only efficient for half
an octave, it is not a Transmission line with the need of
much damping material to dampen
all resonances, it is not a TQWP or ML-TQWP but it
is a combination of all these systems
resulting in a wide-band resonator effective from
40Hz up to 250Hz.
The system is tuned for maximum efficiency
using as less damping material as possible,
no hornyness or honkyness coming
from these using only the few 30mm thick sheets of BAF
as shown in the drawings. The only
thing you have to find is a good place for them in your
room, for more body and bass simply
place them closer to the back wall or even in the
corner (lowest Q drivers), if there
is too much bass or "boom" then simply pull them out of
the corner or move them further
away from the back wall until you have found your
optimal balance.
Below you will find the drawings for our SINGULAR DIY system.

The best material to be used for
this system is 18-19mm Birch Ply, as always
with full-range drivers, this material
gives the most natural tone. The few 30mm
thick sheets of BAF should be placed
as shown in the drawings.

After converting the metric dimensions to workable
numbers, we constructed two basic
cabinets from ¾" Baltic Birch. All joints were
glued and screwed.
