CONNECTING THE SPEAKERS
The CS2.7’s input terminals are located on the lower rear 
of the speaker cabinet. The CS2.7 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

 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 CS2.7s 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

" 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.
