SONICALLY-ADJUSTABLE
HIGH FIDELITY SPEAKERS
USER MANUAL
The CS-1 and CS-2 High Fidelity Speakers have been specially designed to provide unusually high
quality sound when an installation requires a smaller speaker. These sonically-adjustable speakers
provide superior sound 1.) on a shelf or table-top as part of a stereo system in a smaller room and
2.) for a sophisticated desktop computer work station where quality audio is required.
The CS-1, with its 4-inch lower-midrange/bass driver, provides the best sonic solution when a separate
subwoofer system can be employed. The CS-2 with its 5 1/4" lower-midrange/bass driver has a better
frequency balance if it is necessary that it be used alone and a separate subwoofer is not practical.
Both CS-1 and CS-2 models attain their unusually high sensitivity and special performance by using a
built-in adjustable active crossover and a 'booster' power amplifier on the midrange-bass driver. There
is a completely passive crossover on the large two-inch upper-midrange / high frequency dome.
The active crossover / amplifier enables the user to continually adjust both the volume of the lower
midrange-bass cone driver and its crossover frequency relative to the passive dome. It adjusts those
lower-midrange frequencies which are critical to a satisfactory balance in the difficult tabletop and
shelf environment. The speaker adjusts for:
1.) The listener's distance to the speaker.
2.) The immediate physical reflective environment in which it is placed.
3.) The sonic character of the components connected to it.
4.) To suit the user's individual taste and hearing.
This flexibilty means that the speakers can assimilate much more quickly and successfully in a much
wider variety of installations than other speakers.
This flexibility is not meant to substitute for standard bass and treble controls found on preamplifiers,
integrated amplifiers and receivers. Those controls are meant to compensate for frequencies at the
more extreme high and low portions of the spectrum. They will likely be necessary to compensate for
widely varying program material particularly from the internet, for room acoustics and for individual
taste.
Another significant advantage is that the internal 'booster amplifier' increases the gain of the lower-
midrange / bass driver to match that of the much higher sensitivity aluminum dome thereby increasing
the overall sensitivity of the speaker system to around 90 db, 1 watt, 1 meter. That sensitivity figure
includes the bass frequencies around 70 cycles (for the CS-1 with a 4-inch driver) and 50 cycles (for
the CS-2 with the 5 1/4-inch driver) accounting for the unusually strong bass performance of these
speakers. It also makes it possible to use lower-wattage amplifiers, including superior small tube
amplifiers, with such a small speaker.
