Despite its conventional appearance, however, the SCS2 is far
from being "just another bookshelf speaker." For one thing, it is
remarkably heavy for its size - a solid 31 pounds (its price is
correspondingly weighty for a small speaker). And, as our tests
demonstrated, its performance and sound quality are well beyond the
ordinary. The SCS2 was designed to provide exceptional installation
versatility, too. Its rear panel contains a pair of recessed gold-plated
binding posts that accommodate wires, lugs, or single or dual banana
plugs. There are also fittings on the rear that can be used for wall
mounting, with the speakers oriented either vertically or
horizontally.The unique character of the SCS2 becomes more evident when
you unsnap the grille. At first glance, it appears to have only a single
driver,

nominally 6 inches in size, whose silvery aluminum cone, actually
about 5 inches in diameter, Is at the center of the front panel. Closer
examination reveals that there is also a 1-inch metal-dome tweeter with a
mesh protective grille

concentric with the woofer, hence the name Coherent Source.

The term "coherent" refers to a system whose drivers function
to the greatest possible degree as a single sound source, thereby
enhancing the spatial realism of its reproduction. In practice, a single
driver, or a carefully executed coaxial combination of two drivers, is
the most common example of a more or less coherent source. The woofer
has a cast-magnesium frame and, according to Thiel, its voice-coil
diameter is 1-1/4 inches, which is relatively large for a speaker cone
with a diameter of 5

inches. Despite the small size of its woofer, the SCS2 is

recommended for use with amplifiers rated to deliver from 30 to 150 watts.

The SCS2's drivers are magnetically shielded to permit
operation close to a video monitor. Our gaussmeter was barely able to
detect any magnetic flux (less than 0.3 gauss) at any point on the
speaker's exterior. Obviously, this speaker is designed to be thoroughly
compatible with both high-fidelity music and home-theater systems. It
can be purchased individually as a center speaker or in a set of three
for an identical front trio. The SCS2 is a vented system, with two
1-1/4-inch ports located on the front

panel, respectively about 2 inches above and below the woofer rim.
As the speaker is delivered, the ports are blocked with 6-inch-long
plastic foam cylinders that extend almost to the rear of the cabinet.

The speaker has two modes of operation. With the ports blocked
- described as a "port-loaded" condition - the effective bass range
extends only to about 80 Hz, but the speaker's output capability is
maximized. This mode of operation is suggested for use in systems
containing a subwoofer, which will compensate for any loss of lower-bass
response. It is specifically recommended for home theaters.
Alternatively, the ports can be "unloaded" by withdrawing the two foam
blocks. In this mode, which is recommended for two-channel systems
designed for full-range music reproduction, the system's rated bass
response extends to 47 Hz (at the -3-dB point). The foam blocking
cylinders can be replaced at any time to change to the system's other
mode.
