Newton Series T100 Tower Loudspeakers TM INTRODUCTION Introduction Thanks for choosing a Newton Series loudspeaker. The T100 features the finest drivers, precision internal crossover circuitry and an elegant enclosure design. The Product Development Team at Cambridge SoundWorks believes there is no better combination of audiophile-level attention to detail and reasonable cost. AFTER UNPACKING Store the shipping carton and packing material for future transport needs. CONTENTS A) One Loudspeaker B) Two Support Stands C) Six Stand Bolts D) Four threaded posts ("spikes") E) Four disc feet F) Four lock nuts G) Four soft foot pads Also necessary: A philips screwdriver (no.2, preferably) to install the stands Two lengths of speaker wire C D B A INSPECTING FOR DAMAGE Examine the speaker system carefully for shipping damage. If there is any, do not install or use the system. Return the speaker to the store where you made the purchase or call Cambridge SoundWorks at 1-800-FOR-HIFI (1-800-367-4434) for assistance. E F G 1 STAND AND FOOT ASSEMBLY Attach the stands to the base of each speaker using three bolts for each stand (see diagram). The stands are identical. Tighten the bolts securely. Choose which foot option is correct for your situation: Disc Feet: The disc feet insure stable speaker placement on most flat surfaces and low pile carpet. Adhere the four soft foot pads to the bottom of the disc feet if you have a smooth, flat floor surface. The four feet should be used without the pads on carpet. Disc Feet With Spikes: Each threaded post has one pointed end for use as a carpet spike. This point can pierce thick carpeting and support the speaker from the floor underneath. Note: these spikes will make small but deep punctures in most floors. Use the Disc Feet to avoid this. 2 Disc Feet Installation: 1. Install the pointed end of a threaded post into the end of each arm of the metal stands. Twist and hand tighten each post. 2. Thread a lock nut most of the way up each post. 3. Screw a disc foot onto the end of each post about seven complete turns. 4. Apply the self-adhesive foot pads, if necessary for your floor surface. Raise the speaker upright. 5. When the final speaker placement is determined, adjust the position of each disc foot on the threaded post until stable placement has been achieved. Hand twist the lock nut down onto the disc foot to secure. 2. 3. 4. 1. Disc Feet With Spikes Installation: It is difficult to move the speaker once the spikes are installed on the stands. Install the Disc Feet on the speaker first and determine exactly where you want to place the speaker on a carpet, then change the feet to exposed spikes. 1. Install the blunt end of a threaded post into the end of each stand arm. Twist each until it stops turning but do not tighten them. 2. Thread a Disk Foot most of the way up each post. Raise the speaker upright. 3. Adjust each threaded post until stable placement has been achieved. Hand twist the Disc Feet up against the metal stand arm to secure the spike. If you find the spikes are not long enough to pierce the carpet with the Disc Feet installed, you can use the lock nut instead or omit both. Disc Feet Installation 1. 2. Disc Feet With Spikes Installation 3 SPEAKER PLACEMENT For a two channel system (stereo), place the speakers to form an angle between 25 and 55 degrees with your listening position. For a home theater system, place the speakers close to the left and right sides of the monitor. This helps create a cohesive sonic presentation across the left, center and right front speakers. Avoid positioning the face of either speaker near a wall. Reflected sound will degrade the overall accuracy of the speaker's tonal balance Avoid positioning a speaker in a corner. Reflected sound from the corner will also degrade the tonal balance. 20° - 55° ANGLE RECOMMENDED DISTANCE APART FOR STEREO MAXIMUM RECOMMENDED DISTANCE APART FOR HOME THEATER MAIN SPEAKERS CENTER CHANNEL SURROUND SPEAKER SURROUND SPEAKER 45° ANGLE 4 SPEAKER WIRE PREPARATION The T100's can be driven from a receiver, an integrated amplifier or a preamp/power amplifier component system. This manual refers to a "receiver" throughout, but all the instructions apply to integrated amplifers or preamp/power amplifier setups as well. Use at least 18 gauge speaker cable for short runs (under 15 feet). Use 16 gauge or heavier speaker cable for longer runs. 1. Determine how long the speaker cable should be for each speaker. Cut the speaker cable into the appropriate lengths. 2. Strip 1/2 inch of insulation from the two individual conductors in the speaker cable. Twist the exposed strands of bare wire together. 3. Attach any connector plugs (like banana plugs) at this time. 4. Determine which conductor you will use to connect the positive terminals of the amplifier and speaker together. One of the two conductors of a speaker cable can usually be distinguished by printing or a ridge on the insulation. Some times the metal of the conductors has two different colors. Strip 1/2 inch 5 MAKING THE CONNECTION 1. Unscrew the speaker's red and black connector knobs to expose the holes in their threaded shafts. 2. Insert the stripped end of one cable's "indicated" conductor into the speaker's red (+) connector. Hand-tighten the knob to secure the connection. Make sure no stray strands of wire are exposed. If you are using a cable connector plug, connect it according to its instructions 3. Repeat the procedure for the cable's other conductor and the speaker's black (­) connector. 4. Connect the other speaker cable's conductors to the other speaker. 5. Connect the opposite ends of the speaker cable to the speaker outputs of your receiver. Remember to observe channel and polarity (Left Positive, Left Negative, Right Positive, Right Negative). 6 SPECIFICATIONS Dimensions (H x W x D): 32 1/2 x 7 3/8 x 12 1/2 inches (825 x 186 x 320 mm) Base width: 11 3/16 inches (284mm) Weight: 34 pounds The T100 can be safely used with receivers rated above 20 watts per channel. There is little advantage to using a receiver larger than 200 watts per channel with these speakers, but any size receiver may be used should it be available, so long as the receiver is not operated at excessive levels. Warning About Excessive Amplifier Distortion Operating a receiver (of any power rating) beyond its maximum undistorted output level creates distortion - added highfrequency sound not part of the musical program. Distortion dramatically increases the internal operating temperature of a loudspeaker and will eventually cause the speakers to fail due to burned or melted internal parts. While Cambridge SoundWorks includes the most heat-tolerant parts commensurate with good acoustic design, the speaker's Limited Warranty against defects in materials or workmanship does not apply to parts that show evidence of having failed from long-term operation at very high temperatures. Enclosure Cleaning The speaker enclosures can be cleaned with a windowcleaning product. Use a soft, lint-free cloth only. Avoid spraying any cleaner on the grille panels. Brush or vacuum the grille panels if dust accumulates on them. 7 CAMBRIDGE SOUNDWORKS, INC. 26 Dartmouth Street, Westwood, MA 02090 Telephone: 1-800-367-4434 Fax: 1-978-475-7219 P81-2120 ...
