Introduction

NHT’s C- Series represents our best efforts in passive loudspeaker design. The C- Series is based on the same design fundamentals that established NHT’s reputation for accuracy and high performance, and adds new driver and cabinet technology which reduce distortion and improve dispersion.  The result is a more        articulate, more musical listening experience.

The following Setup Guide will help you unpack, connect, and place your new C- Series loudspeakers in your listening room.  If you are interested in specifications or in technology used in the design, please visit our web-site at www.nhthifi.com and look up information on your specific model.  If at any time during or after setup you require assistance, feel free to call our Customer Hotline at 1-800-NHT-9993 (800-648-9993).

This Setup Guide addresses the following models:  NHT C-1 and C3 bookshelf speakers, C-4 tower speaker and C-LCR center channel/LCR.

Unpacking your Speakers

As you unpack your C-1, C-3 and C-LCR speakers, you will notice adhesive- backed, rubber bump-ons included in the carton.  You will need to stick these on the bottom of the speakers near the four corners if you are placing these on a table or bookshelf. They will serve to keep the speaker from sliding around and to protect the bottom surface from scratches.

The C-4 may require the help of a friend to unpack it due to its weight and size.  The C-4 has a flat bottom and comes with stabilizers that which attach to the bottom of the speaker. Position the speaker on its back and prop up the bottom section with some of the foam packing materials. Fasten the stabilizers using the        supplied machine screws (See Fig. 1) using a philips head screwdriver. The stabilizers for the C-4 also include rubber cones.  The rubber cones are ideal for use on wood or tile floors. They can be adjusted if you have an uneven floor and include a locknut to lock them down. We recommend you use metal cones when placing the C-4 on heavy carpet flooring to add stability.  Metal cones can be purchased at nhthifi.com.

Placement

NHT’s C-3 and C-1 speakers can be placed on stands, on shelves or hung on the wall.  Given the high performance of these models, NHT recommends placement at close to ear level to achieve maximum fidelity.  The C-1 is a 2-way design and stereo imaging will benefit from a slight “toe-in” towards the listening position.  The rest of the C-series are all 3-way designs and can be placed without any toe-in angle.

If you decide to wall mount the C-3, there are threaded inserts on the rear of the cabinet for wall mounting. NHT recommends the use of Vantage Point Bookself Mounts brackets. These are available at www.nhthifi.com in the accessories section.

The C-LCR can be used as the main left & right, rear surrounds and center channel. Its dispersion character-istics allow for horizontal or vertical orientation. However, if you are using the C-LCR as a center channel, you should place it horizontally.  Ideally, the center channel should be placed as close as possible immediately above or below the television, with the tweeter closest to the TV (Fig. 2)

It is important to know that small changes in speaker position can have a notable effect on sound quality.  Moving speakers closer to walls or corners will increase mid-bass output, but may result in artificial “boominess”. Placing them farther away from room boundaries tends to decrease bass output yet improve stereo imaging and detail.  We recommend a distance of 6” – 12” from the rear wall if possible.

Room furnishings also play a significant role.  Soft furnishings (e.g. sofas, carpets, and curtains) tend to absorb mid and high frequencies, which can result in perceived dullness, whereas hard surfaces and sparse furnishings tend to have the opposite effect.

Thus, experimenting with the effects of different placements in your own listening environment is the key to finding the sound you like best.

Here are some tips for maximizing the performance of your speaker system:

• Position the speaker 1.5 times as far away from you as they are from each other. (Fig. 3)
• Left and Right speakers should be equidistant from the listening position.
• Try to keep tweeter height close to ear level when in the listening position.
• Bookshelf speakers should be placed upright.
• Try to keep the speakers flush with the front edge of shelves or cabinets.
• The C-Series should not require long break in time, play music for an hour or so is sufficient.
• For surround systems, use the same basic setup (all shown in Fig. 4) and when possible:
• Place the C-LCR center channel speaker right above or right below the TV. If you need a wall mount, check out the Pinpoint AM-15 available at www.nhthifi.com on the accessories section.
• Place the rear speakers in an equilateral triangle with the listening position, at least 5’ apart.
• Rear speakers should be at the same height, or higher than, the front channels.

Unfortunately many rooms will not allow ideal placement.  As a general rule, try to keep the rear channel       speakers equidistant from the center of the listening area.  If the rear speakers have to be close to the main seating area, we recommend adding time delay in your surround processor to make them seem farther away, and make sure they are placed, above the heads of the listeners.

Connections

Before connecting your C-Series speakers to the receiver/amplifier, turn off the AC power to avoid potential damage to your components.

The terminals on the back of your speakers accept raw wire, banana plugs or spade lugs.  Note that these terminals should be tightened only by hand, as excessive force can break them.  We recommend your speaker wire be at least 16 gauge, 14 gauge for longer runs.

Prepare the wires by stripping 1/4” – 3/8” of insulation from the ends and tightly twist the exposed strands.

Finally, connect your speakers to your amplifier or receiver, making sure that the speakers are “in phase,” that is, the same half of the wire pair connected to the Positive terminal (+, usually red) on both the amplifier and the speaker.  The other half of the same wire connect to the Negative (-, usually black) terminals on both amplifier and speaker.

Most speaker wire has one half of the pair marked with either lettering, ridges, the “+” sign or color to help you make the proper connections.

Before powering up the receiver/amplifier, make sure there are no stray strands from one terminal touching the other terminals.

Operation

All NHT C-Series speakers are compatible with most amplifier power ranges and are designed to handle a wide range of listening levels.  Every speaker, however, has limits.  Speaker damage most often occurs from sustained high volume levels in some or all frequencies.  Try to avoid excessive bass or treble settings or equalizer boosts.

The best tool you have is your ears.  If you hear unusual distortion or breakup, decrease the volume immediately.  If you are unsure, place your hand close to the woofer. If you feel heat radiating from the driver, you are playing the system beyond its limits.

Maintenance

Your NHT speakers will require little if any maintenance under normal use. Try to avoid exposing them to      direct, sustained sunlight, high temperatures or moisture.  Cabinets can best be dusted using a clean, soft chamois cloth.  The finish on your speakers is durable but dry rough cloth and/or excessive force can leave fine scratches over time.  Try to avoid using liquid cleaners and household furniture polish, particularly around the speaker components.  To clean the grilles, remove them from the speaker and use a soft brush or a vacuum on its lowest setting.  Do not attempt to clean the speaker components.

FREQUENTLY ASKED QUESTIONS

Are NHT speakers good?****

The NHT C3 has an outstanding build quality that gives you the impression that you possess a high-end speaker with a stunning look and sound. It features a smooth piano glossy surface, three drivers up front, and high-end connectors at the back.

What is an LCR center speaker?****

Any home theatre system must have LCR/center channel speakers. Usually above or below the screen, and faithfully reproduces almost all of the conversation as well as many of our favorite special effects, such jet engines and explosions.

Does a center channel speaker make a difference?****

A home theatre system’s center channel speaker is essential since it reproduces around 70% of the dialogue from movies and television shows. You’re missing out on important details of what you’re watching without one.

What frequency should I set my center speaker to?****

Playback of dialogue by the center speaker occurs primarily in the midrange of the frequency spectrum. The fundamental frequency for men is between 100 and 125 Hz, whereas for women it is between 200 and 250 Hz.

Where are NHT speakers made?****

NHT Loudspeakers (Now Hear This), sometimes known as NHT Audio informally, is an American manufacturer of loudspeakers and audio components with headquarters in Benicia, California.

Which is better 4ohm or 8ohm speakers?****

For lower power, 4-ohm lower impedance is typically recommended, and for larger power, 8-ohm impedance is typically employed. There are two ways to connect numerous speakers—in parallel and in series—and an amplifier must be added.

Should the center channel be louder?****

No, the middle shouldn’t be louder than the fronts when tuned properly. The center is not louder because of the setup’s numbers (or not as loud). These modifications are available to help you accommodate for variations in loudness among speaker models.

Is center speaker good for music?****

The center channel speaker in a home theatre surround sound system is undoubtedly the most significant and underappreciated. Almost 70% of all audio content is currently played through the center channel. The majority of the vocals and dialogue in both music and movies are also handled by it.

Can I use just a center speaker?****

The center channel speaker can still be used independently and still produce excellent sound.

Is a sound bar better than a center speaker?****

In the end, using a soundbar as a center channel speaker would be a mistake. Choose between a soundbar (and subwoofer) or a set of surround sound speakers if you want to make an investment in a home audio system. While the latter often produces higher sound quality, the former is cheaper.

How big should my center channel speaker be?****

For timbre matching purposes, your Center channel should typically be set to the same size as your Front L/R speakers. Of course, you should set it to “Small” if your center channel speaker is incapable of handling the full range.

Should center channel have bass?****

You don’t require a lot of bass from your center channel speaker. That’s because the center channel of the majority of movie soundtracks doesn’t contain a lot of bass information.

What amplifier do I need for 8 ohm speakers?****

An amplifier that can deliver 700 watts into an 8-ohm load is necessary for a speaker with a nominal impedance of 8 ohms and a continuous power rating of 350 watts (more on impedance in the section that follows). For a stereo pair of speakers, the amplifier should be rated at 700 watts per channel into 8 ohms.
