doesn't everyone do  this?  Because  it  is
more expensive to build an enclosure on
an angle.

The  front  edges  of  the  enclosure  are
beveled.  This  reduces  air  turbulence
from the drivers, and reduces coloration
of  the  sound.  Again,  it's  an  expensive
piece of carpentry to do this.

The  CS2.4s  are  4  Ohms  nominal  and
medium  sensitivity,  so  a  high  quality
amplifier must be used to drive them.

The Sound

I  tested  the  CS2.4s  with  a  McCormack
CD Transport and DAC, Balanced Audio
Technology  VK-5i  preamplifier,
Balanced  Audio  Technology  VK-500
Power  Amplifier,  McIntosh  MC-602
Power  Amplifier,  and  Nordost  Cables.  I
toed  the  speakers  in  at  about  15

0

towards my listening position.

It  took  several  days  of  constant  music
playing  to  break  these  speakers  in,  but
the  major  change  occurred  in  the  first
couple of hours. They started out with a
slightly  harsh  upper  end  and  thin  bass,
but  they  soon  opened  up.  I  broke  them
in with some pretty heavy music, played
at  medium  volume,  with  about  30  -  60
watts of power.

I  have  to  say  right  off  the  bat  that  the
CS2.4s are some of the best speakers I
have  ever  heard.  The  soundstage  was
very tall, as if the whole wall were alive,
almost  like  listening  to  my  planar
speakers.  However,  planar  speakers
sometimes  tend  to  lose  a  bit  of  detail
because the sound is coming from such
a  large  surface.  The  CS2.4s,  on  the
other  hand,  although  having  a  large
soundstage,  still  maintained  a
magnificent amount of detail, probably in
part  because  of  the  coincident  tweeter
and midrange drivers.

The  bass  was  tight,  never  boomy  or
chesty,  the  mids  were  clean  and  never
overly  sibilant,  and  the  upper
frequencies  were  crisp  without  being
edgy.

One of my favorite CDs of all time is the
Telarc  recording  of  Copland's  Fanfare
for  the  Common  Man.  It  has  high
pitched trumpets and thundering bass. It
is also a good test for any audio system.
The  Thiel's  handled  this  piece  in  stride,
without breaking up at all. The bass was
tight and clean, and the huge bass drum
used in this recording is a stress test to
end  all  tests.  (You  can  click  on  any  of
the album cover art photos to see more
details, including catalog numbers.)

Tony  Bennett,  Mary  Chapin  Carpenter,
and  Natalie  Cole  stand  close  to  their
microphones,  and  their  voices  are  so
clear,  that  any  chestiness  or  sibilance
produced  by  speakers  becomes  very
apparent.  The  CS2.4s  put  these  terrific
performers  into  my  room  for  a  private
concert, with no hint of such artifacts.
