1. cleared the carpet Also tilting the speaker so its weight is resting on any single pin can damage the wood base Please be cautioned that the pointed pins can be dangerous if not used with care They can cause small dents in hardwood floors and it is possible to damage carpets if the speakers are moved incorrectly with the pins in place BREAK IN The CS2 3 s like most speakers require a period of playing before they perform optimally The time depends on how loudly the speakers are played more time is required if played softly less if played loudly At least 50 hours at moderately loud levels are required before the speaker is performing near optimum You should notice even more improvement after 100 hours of playing ASSOCIATED EQUIPMENT The CS2 3 is a very high quality sound reproducer and will benefit from use with the best associated equipment Since it is extremely accurate it will reveal sources of distortion generated elsewhere in the system For example distortion resulting from poor recordings or inferior electronics will be reproduced accurately Also the quality of the interconnect cables and speaker cables will significantly effect the performance of the system POWER REQUIREMENTS It is important to have enough power to play at the level you desire without distortion If high sound levels are desired the CS2 3 s are designed to be used with amplifiers rated up to 400 watts per channel into 4 ohms If you play the2. a low efficiency of 84dB W m will require twice the power of an average 87dB W m speaker and one with a high rating of 90dB W m will require only half the power of an average speaker Usually high efficiency can be obtained only by trading off sonic quality there are very few speakers that provide a very high level of both The CS2 3 is of average efficiency 87dB and therefore requires a normal amount of power 3 A small room will need less power for a given loudness level than a large room A very small room of 1000 cu ft 11 x 11 with an 8 ceiling will require about half the power of an average size room A large room of 6000 cu ft 20 x 30 with a 10 ceiling will require twice the average power If the listening room is connected to another room by a large open area the required power will increase but not by the amount of the combined room volume If the room has a dropped ceiling with light panels the ceiling will be almost transparent acoustically and the space above the ceiling should be added If the panels are heavy they will act as a more normal ceiling With all this in mind a person who doesn t like to play music very loudly and has a small room can get quality sound with as little as 50 watts whereas a person who sometimes likes to play loudly and has a large room may need 400 watts or more CABINET FINISH CARE THIEL wood cabinets possess a high quality lacquer finish that is both beautiful and durable However any w
3. speakers more loudly than the volume the amplifier can cleanly produce the amplifier will produce overload clipping distortion The sound will become compressed strained and in extreme cases obviously distorted This distortion is actually non musical additional energy and since it is concentrated in the high frequency region where the speaker is least able to handle it tweeters can be damaged in extreme cases Keep in mind that sound quality is usually much more important than sound quantity There can be large differences in the sonic performance of two amplifiers of equal power and this is more important than large differences in power Most everyone will be happier with a 100 watt amplifier of high sonic quality than a 200 watt amplifier of mediocre sonic quality For this reason we feel there is no substitute for listening in making your amplifier decision The question how much power do I need does not have the simple answer most people expect because it is not determined only by the loudspeaker s efficiency but also by the volume desired and the size of the room If all three factors are average about 100 watts per channel is required Each factor can raise or lower this amount by about three times 1 Usually people who don t like music loud can decrease their power to about one half Also people who like music loud should increase their power by 2 times or more Most people fall within a normal range 2 A speaker with
4. to a wall the bass response is stronger and placing a speaker in a corner will make it even more so In order to achieve properly balanced bass it is necessary for the speaker to be used in the environment for which it was designed THIEL speakers are designed to provide accurate bass when positioned away from all walls the same position that provides the best imaging Listener position The CS2 3s provide broad dispersion of energy at all frequencies and therefore provide good results throughout a large listening area Best imaging is provided for a listener centered in front of the speakers Optimum phase and time alignment is provided only for a seated listener who is eight or more feet away from the speakers All aspects of speaker placement are dependent on the particular room Since every room is different no hard rules can be given and experimentation is necessary to achieve the best results CONNECTING THE SPEAKERS Bottom view of cabinet The CS2 3 s input terminals are located on the bottom of the speaker To gain access to them the speaker should be laid on its back or side Make sure that all connections are tight 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 input terminal of each speaker should connect to the respective positive output terminals of the amplifi

6. THIEL Model CS82 3 Coherent Source loudspeaker system OWNER INFORMATION ENGINE E 3 te Q o gt CONSUMER ELECTRONICS SHO C ongratulations on your purchase of the THIEL model CS2 3 loudspeaker system This fine product is the result of a dedicated effort to provide very accurate music reproduction We have used very high quality components and taken great care in the CS2 3 s construction Properly set up and used with good associated equipment the CS2 3 will provide you with a great deal of musical enjoyment for many years SPEAKER PLACEMENT The CS2 3s are relatively noncritical to room placement and will provide good results from almost anywhere However here are some guidelines to help you achieve the best sound from your speakers Speaker placement will affect the accuracy of timbre spatial performance and bass performance Distance from walls THIEL speakers and most others sound best if they are placed well away from all walls Such placement optimizes imaging and depth and musical timbres are reproduced with the least coloration because it allows the initial sound coming from the speaker to be distinctly separated in time from the secondary sound of wall reflections If reflections are heard too quickly after the primary sound your brain tends to interpret them as part of the initial sound causing the perceived timbre to be altered and the spatial characteristics to be confused If you experime
7. ed stabilizer pins The stabilizer pins are pushed into three pre drilled holes in the base under each speaker The pin point penetrates the carpet and allows the speaker to rest firmly on the floor The three pins provide a stable foundation which eliminates some obscuring of information and produces a cleaner more articulate sound No pins are required when placing the speakers on hard or smooth surfaces There are some applications where the stabilizer pins will not bring an improvement in sound but may actually make it worse This situation occurs when the floor itself is not rigid and therefore vibrates when connected to the speakers via the stabilizer pins We encourage you to experiment to determine for yourself whether or not this is the case We recommend that you determine the position of your speakers before inserting the pointed stabilizer pins To insert the pins tilt the speaker forward and push the two back pins fully into the 1 deep holes located in each back corner of the base Then rock the speaker backward and insert the front pin Finally press firmly on the top of the speaker with a slight rocking motion until the pins penetrate the carpet completely To check that the pins are firmly seated lightly tap the back and side of the speaker There should be no movement and the speaker should feel solidly in place If the speaker is moved with the pins in place care should be taken to lift the speaker straight upward until all the pins have
8. er the wire connected to the black input terminals should be connected to the respective negative output terminals of the amplifier Stabilizer Pins 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 E Coherent Source LOUDSPEAKER vove CS Esa CE usually give the best results Due to European CE regulations that do not permit banana plug type loudspeaker connections we ship THIEL speakers with removable plugs installed in the ends of the binding posts If you wish to use banana plug type connections you may remove the black plastic plug inserted into the end of each age Input Terminals metal binding post cap To remove the plug use your fingernail to pry along the bottom edge of the plastic insert and lift out STABILIZER PINS The speakers should be positioned before the stabilizer pins are installed Speakers positioned on a soft surface such as carpeting are able to rock back and forth slightly and will vibrate in reaction to those forces the speaker generates to move the driver diaphragms Every action has an equal and opposite reaction This motion of the speaker causes a loss of musical information and reduces the clarity of the music To eliminate this effect the THIEL CS2 3 can be used with the provid

10. nt you will notice a major improvement in openness when the speakers are even two feet from the rear wall instead of one We like to see the speakers three feet from the rear wall and five feet from the side wall Also it is not desirable for large objects to be placed near the speakers since these will also be a source of unwanted early reflections that reduce imaging accuracy Spacing Because of their very wide even dispersion of energy THIEL speakers should usually be placed farther apart than most Optimum imaging is usually achieved when the speakers and the listener form an equilateral triangle although this will depend on the width of the room a narrow room will require closer placement If the speakers are too far apart for a given environment there will tend to be a hole in the middle of the sound stage if they are too close together the image will be compressed and will not achieve optimum width Aiming We usually prefer the imaging obtained when the speakers are pointed straight ahead rather than pointing toward the listener This placement produces the largest most natural soundstage However toeing the speakers in somewhat may produce more specific placements of instruments Also if it is not possible to get the speakers far enough away from the side walls a toed in position can be helpful to reduce the strength of wall reflections Bass Bass response is also affected by speaker placement In general when a speaker is close
