Frequently Asked Questions - Classic Two C NHT Audio

What is the recommended amplifier power for the Classic Two C?

An amplifier with 20-150 watts RMS per channel at 8 ohms is ideal. The speaker handles up to 100 watts RMS comfortably.

Can I place the Classic Two C on a bookshelf?

Yes, but ensure there is at least 6 inches of clearance behind the speaker for the rear port. Avoid placing them inside enclosed cabinets to prevent bass distortion.

Does the Classic Two C support bi-wiring?

Yes, the speaker has two sets of binding posts connected by metal jumpers. For bi-wiring, remove the jumpers and connect separate cables to the tweeter and woofer terminals.

What type of speaker wire should I use?

Use 14-16 AWG speaker wire for distances up to 50 feet. For longer runs, 12 AWG is recommended to minimize resistance.

How do I clean the speaker cabinet?

Use a soft, dry microfiber cloth to gently wipe the cabinet. For stubborn dirt, slightly dampen the cloth with water and wring thoroughly. Never use chemical cleaners or abrasive materials.

What is the frequency response of the Classic Two C?

The official frequency response is 45 Hz to 20 kHz, with a smooth roll-off below 50 Hz. For deeper bass, consider adding a subwoofer.

Can I use the Classic Two C as a center channel speaker?

While designed as a bookshelf speaker, it can be used as a center channel if placed horizontally. Ensure the tweeter remains at ear level for optimal imaging.

Does the speaker have magnetic shielding?

The Classic Two C has limited magnetic shielding. Keep it at least 12 inches away from CRT TVs or monitors to avoid interference.

What is the warranty for NHT speakers?

NHT typically offers a 5-year limited warranty for speakers. Check with your retailer or NHT customer support for specific terms.

Can I wall-mount the Classic Two C?

The cabinet does not have built-in mounting points. Use a sturdy shelf or stand. If wall-mounting, use a universal speaker bracket designed for the weight, but ensure the rear port is not blocked.

Setup Guide

NHT's Classic Series represents our best efforts to date in passive loudspeaker design. Classic starts with the design fundamentals that have made NHT's reputation for accuracy and high performance, and adds new driver and cabinet technologies which reduce distortion and improve dispersion. The benefit to you is a more articulate, more musical listening experience.

All Classic Series models share a similar "voice" or tonality so that you are assured a matched system no matter which models you decide to add as you build your system.

The following Setup Guide will help you unpack, connect and place your new Classic loudspeakers in your listening room. If you are interested in specifications or the technology used in the design, please visit our website 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: Two C and the Three C center channel speakers. Both are 3-way, acoustic suspension systems, the Three C offering deeper bass and higher output than the Two C. NHT uses a 3-way design for its Classic center channels to provide wider dispersion and lower distortion, so that even if you are listening off axis, the tonality of vocals and dialog remain consistent and clear.

Unpacking your Speakers

You will also notice an unusually shaped piece of foam with an adhesive backing. The purpose of this foam is to reduce unwanted reflections caused by interaction between the tweeter and midrange drivers. To get the best performance from the Two C and Three C, install this foam part. Fig. 1 demonstrates where to mount the foam part.

Placement

NHT's Classic center channel designs are meant to be placed horizontally. Ideally the center channel should be placed immediately above or below the television, in as close proximity as possible (Fig. 2).

The three front speakers in a home theater system sound best when placed at the same distance and the same height in relation to each other. In addition, try if possible to have the tweeter height close to ear level when sitting.

Try to position the front of the center channel to be even with the front of the television or shelf on which it is placed. This eliminates undesirable reflections and improves intelligibility of the speaker.

Connections

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

Take a look at the terminals on the back of your speakers. They can accept raw wire, banana plugs or spade lugs. Note that these terminals should be tightened only by hand, as excess force can break them. We recommend your speaker wire be at least 16 gauge. Your NHT dealer can recommend the correct wire. Use the same length of wire for each channel.

Prepare the wires by stripping 14 " - 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 connected 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 your receiver/amplifier, make sure there are no stray strands from one terminal touching the other terminals. Also, try to keep speaker wires from laying across AC power cords.

Operation

All NHT Classic speakers are compatible with most amplifier power ranges and are designed to handle a wide range of listening levels. Every speaker, however, has limits and it is important to listen for them. 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 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 can leave fine scratches over time. Try to avoid using liquid cleaners and household furniture polish, particularly around the speaker components. To clean 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.

Satisfaction

We hope you enjoy the sound of your NHT Classic speakers as much as we do. Your warranty is printed on the back of this Setup Guide. Once again, if you have any questions or problems, please call us at our Consumer Hotline.
