Thiel Audio Products CS2.3 manual Connecting the Speakers, Stabilizer Pins

CONNECTING THE SPEAKERS

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 amplifier; the wire connected to the black 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.

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 metal binding post cap. To remove the plug, use your fingernail to pry along the bottom edge of the plastic insert and lift out.

Input Terminals

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 provided 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 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.
