Thiel Audio Products CS3.7 Speaker User Manual


 
CONNECTING THE SPEAKERS
The CS3.7’s input terminals are located on the
lower rear of the speaker cabinet. The CS3.7 uses
5-way binding posts that accept several types of
wire connections. Regardless of the type of wire
termination, make sure that all connections are
tight. The input terminals are designed to be easily
tightened by hand or a
1
2 inch nut driver can be
used.
It is essential for proper performance that both
speakers in a stereo system be wired in the same
polarity. The speaker’s input terminals are color
coded to facilitate this. The wire connected to the red
ringed input terminal of each speaker should connect
to the respective positive (+) output terminals of the amplifier; the wire connected to the black ringed input terminals
should be connected to the respective negative (–) output terminals of the amplifier.
The speakers should be connected to the amplifier with high quality cable to ensure minimal loss of power and proper
control by the amplifier. If the speakers are being connected to a vacuum tube amplifier with various impedance taps,
the 4 ohm tap will usually give the best results.
STABILIZER FEET
The speakers should be positioned before the stabilizer feet are installed.
Speakers positioned on a soft or uneven surface are able to rock slightly and will vibrate
in reaction to forces the speaker generates to move the driver diaphragms. (Every action
has an equal and opposite reaction.) This motion slightly reduces the music’s clarity.
To eliminate this effect, the CS3.7s can be used with four stabilizer feet on uneven
surfaces or on carpeted floors to provide a more solid footing and allow the speaker to
couple more firmly to the floor. To install the feet:
• Position the speaker in the desired location.
• Tilt the speaker forward slightly so that the back of the speaker is a few inches off the
floor.
• Screw one foot, with the locking nut threaded all the way onto the foot, into each of the
two holes at the back corners of the speaker bottom. The pins should be screwed into the
speaker until there is about
1
4" of thread remaining visible.
• Let the back of the speaker down and then tilt the speaker backward slightly so that the
front is a few inches off the floor and install the two front feet.
• With all four feet installed, the height of each foot should be adjusted so that the speaker stands firmly on the
floor without wobbling. Then tighten the lock nuts by turning them so they are tight against the cabinet to secure the
feet to the cabinet
Please be cautioned that the stabilizer feet can dent hardwood floors and it is possible to mar the floor’s surface if
the speakers are moved with the feet in place.
