WRIGHT AUDIO
CS-1 / CS-2 TABLE / SHELF
SONICALLY-ADJUSTABLE
HIGH FIDELITY SPEAKERS
USER MANUAL
The CS-1 and CS-2 Hi h Fidelity Speakers have been specially desi ned to provide unusually hi h
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-midran e/bass driver, provides the best sonic solution when a separate
subwoofer system can be employed. The CS-2 with its 5 1/4” lower-midran e/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 hi h sensitivity and special performance by usin a
built-in adjustable active crossover and a 'booster' power amplifier on the midran e-bass driver. There
is a completely passive crossover on the lar e two-inch upper-midran e / hi h frequency dome.
The active crossover / amplifier enables the user to continually adjust both the volume of the lower
midran e-bass cone driver and its crossover frequency relative to the passive dome. It adjusts those
lower-midran e 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 hearin .
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,
inte rated amplifiers and receivers. Those controls are meant to compensate for frequencies at the
more extreme hi h and low portions of the spectrum. They will likely be necessary to compensate for
widely varyin pro ram material particularly from the internet, for room acoustics and for individual
taste.
Another si nificant advanta e is that the internal 'booster amplifier' increases the ain of the lower-
midran e / bass driver to match that of the much hi her sensitivity aluminum dome thereby increasin
the overall sensitivity of the speaker system to around 90 db, 1 watt, 1 meter. That sensitivity fi ure
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) accountin for the unusually stron bass performance of these
speakers. It also makes it possible to use lower-watta e amplifiers, includin superior small tube
amplifiers, with such a small speaker.

listener's ear level when placed on a desk or table durin computer use.
•4-inch lower midran e-bass driver with aluminum cone and lon -travel suspension.
•2-inch upper midran e-tweeter driver with aluminum dome provides extreme clarity.
The aluminum composition of both the diaphra ms is the reason the speakers' sound character
remains consistent from bass to treble.
•Continuously variable volume level and frequency crossover points affectin the bass-lower
midran e relative to the upper-midran e / tweeter.
•8 ohms. Sensitivity: 90 db 1 watt @ 1 meter. 25-watt watt internal woofer-lower midran e
power amplifier.
•Passive crossover with no resistors or attenuation to the two-inch midran e-tweeter dome.
•Hi h durability black textured finish.
•Size: 17"H x 6 7/8"W x 7 ½" D
•Wei ht: 12 lbs.
•3-Year Warranty. See website for details
•For 115-120VAC, 60 Hz.
•Made in U.S.A. with U.S. and Global parts.
CS-2 Features (with 5 1/ -inch midrange-bass driver)
Includes all the CS-1 features plus:
•Substitutes a lar er 5 1/4-inch bass-midran e driver in a sli htly lar er cabinet: 17”H x 6
7/8”W x 9”D. Wei ht: 14 lbs.
•Adds an RCA line level input for use with a preamplifier output for the lower mid-ran e / bass
driver plus a separate speaker-level upper midran e-tweeter input for maximum hookup
flexibility.

CS-1 Connection:
Refer to dia ram on the back of the speakers.
1.) Speaker Input
The speaker-level input usin sprin clip type jacks to permit connection with bare wire. Connect the
speaker-level output of a full-ran e amplifier to the input usin standard speaker wire eiher 18 or 20
au e.
The pair of sprin clips to the ri ht are not used in this model.
2.) The pair of RCA jacks are not used on this model. Do not insert any plu s in these sockets.
3.) To Subwoofer
Speaker-level passthrou h outputs are full-ran e for connection to an external subwoofer system.
4.) Power Input
This unit features an externally accessible 0.75A, 250V fuse and USA polarized 2-pin plu . This unit
is not suitable for 220-240V applications.
CS-2 Connection Options:
Refer to dia ram on the back of the speakers.
To provide flexibility, there are two ways of connectin this speaker. Dependin on the external
amplifier used, one method may sound better than the other.
Method 1: Using speaker-level signal from the amplifier only:
1.) Speaker Input
The speaker-level input uses sprin clip type jacks to permit connection with bare wire. Connect the
speaker-level output of a full-ran e amplifier to the input usin standard speaker wire either 18 or 20
au e.
The pair of sprin clips to the left are not used in this model.
2.) Connect the supplied red and black wires from the Hi h Frequency sprin clip type jack
connections to the recessed bindin posts above. Observe the polarity of the connection, connectin
the black wire to 'minus' and the red wire to 'plus' on both the sprin clips and the bindin posts.

Method 2: Using a full-range, line-level RCA preamplifier output and the speaker-level signals
simultaneously. (NOTE: A home theater receiver with an LFE (Low Frequency Effects) RCA
output will not work properly.)
1.) Do not use any of the sprin clip connections.
2.) Connect the speaker-level output from amplifier directly to the recessed cup with bindin posts
observin the correct plus and minus polarity.
3.) BOTH RCA jacks on the speaker's back must be connected in parallel for connection to the
amplifier's preamplifier output section. This is accomplished with a short "y-connector" consistin of
one female RCA socket to two RCA male plu s which is included.
Plu the two male plu s into BOTH RCA sockets on the speaker and use an RCA interconnect the
appropriate len th to your amplifier's preamplifier section output.
NOTE: When this method is used, the "Su ested Settin s" as shown on the rear of the speaker will
likely not be accurate.
AC Power Connection
To avoid the possibility of hum, all the components should be connected to the same power strip.
Cable TV systems can cause hum from the speakers as well. Try disconnectin all coaxial feeds that
are connected to the system. If this solves the problem, install a coaxial line isolator and reconnect the
system. In the very worst case, a line-level audio isolator/transformer connected to the line-in of the
subwoofer amplifier will usually solve the problem.
Note 1: When the power switch is turned 'Off', each amplifier still draws about 7 watts of power.
When it is turned on and left idle, the amplifier draws about 8 watts. In order not to disturb the "Gain"
settin , the amplifier may be left on continually. If this is not desired, AC Power ON / OFF remote
controls are available throu h Amazon and is recommended.
Note 2: It is normal for the amplifiers' panel to become very warm, even when the power switch on the
amplifier is turned off.

CS1 and CS2 CONTROLS / INDICATORS
As a a starting point, adjust the controls to conform with the positions shown on the diagram on
the back of the speaker. In many, if not most situations, these positions will remain as the ideal
settings.
Further adjustments of the controls may be found either by measurement instruments at the
listener's position or by ear using an average setting found by listening to a wide range of
program material. If the amplifier has Bass and Treble Controls, leave them at the 'flat' position
during this process.
1.) Power / Gain Control ("Gain")
This control adjusts the volume of ONLY the lower-midrange / bass driver. When the power/
gain switch is turned to the "On" position, the LED will illuminate and the amp will be in "On'
mode. If the LED is not illuminated, check that the amplifier is plugged into a power source and
that the "Gain" knob is not set to the "Off" position.
2.) Frequency Control (Crossover Point)
This control is used to adjust the highest frequency that the lower-midrange / bass driver will
reproduce.
IMPORTANT NOTE:
The settings are not meant to be something fiddly requiring constant readjustment. Once the
ideal settings are found, use the amplifier's Bass and Treble Controls to provide any further
adjustment required and leave the speakers' settings alone.
When making Gain and Frequency Crossover adjustments, make sure both speakers are closely
matched. When deviating from the suggested settings, move the controls only in half-step
increments (between the marked lines) as small setting changes can be sonically significant.
The 'Suggested Settings' are the conditions when a listener is sitting at a computer desk with the
speakers at somewhat less than arm's length away with the speakers on either side of the monitor.
At farther distances, the "Gain Control" may have to be slightly increased.
