Klipsch R-30C Center Channel Speaker for Home Theater

The Klipsch R-30C center channel speaker is designed for a passive home theater system and its center audio channel. Its slim cabinet fits beneath a flat-screen TV. The design combines a 90° × 90° Tractrix horn, an aluminum tweeter, and 3.5-inch TCP woofers.

The Role of the Center Channel

A center speaker reproduces the sound assigned to the center channel by an AV receiver. In movie systems, this channel usually carries dialogue and sound events occurring in the center of the screen. The R-30C is not a standalone soundbar. It requires an AV receiver or another amplifier with an output for a passive center speaker.

The tapered array crossover coordinates the operation of the woofers and tweeter. It is intended to improve sound dispersion and midrange definition, which is especially relevant when listening to dialogue from different seating positions.

Horn and Drivers

The Tractrix horn has larger outer dimensions and provides 90° horizontal and vertical dispersion. This consistent dispersion geometry makes it easier to position the speaker in relation to the screen and the main listening position.

The horn houses a 1-inch LTS aluminum tweeter with a Kapton suspension. Aluminum is lightweight and rigid, making it suitable for tweeter construction.

The 3.5-inch TCP woofers are made from thermoformed crystalline polymer and finished with a copper coating. Their cones feature a steeper angle. Together with the crossover, these drivers cover the bass and midrange region that is important to the center channel.

Connecting It to a Home Theater System

This is a passive speaker, so it does not contain a built-in amplifier. Connect it with speaker cable to the center-channel speaker output on an AV receiver. HDMI, optical, and TV line-level audio outputs are not suitable for a direct connection.

Maintain the same polarity at both ends of the cable. Connect the amplifier’s positive terminal to the speaker’s positive terminal. Incorrect polarity can impair integration between the center channel and the front speakers.

System Setup

Enable the center channel in the AV receiver’s menu, then run its automatic room calibration. This can establish initial level, delay, and crossover settings. After calibration, check dialogue reproduction from the main listening position.

If voices sound too quiet, first adjust the center-channel level in small increments. Do not increase the amplifier’s overall volume solely to make dialogue louder. This helps maintain a more appropriate balance with the left and right speakers.

Placement Near the TV

The low-profile cabinet is convenient for placement beneath a flat-screen TV. Center the speaker relative to the screen so that dialogue appears to come from the picture. Do not allow a shelf edge or other objects to obstruct the front.

If the speaker sits well below ear level, angle it toward the main listening position. Keep the horn and driver area completely unobstructed. The removable low-profile magnetic grille lets you choose between a covered or exposed front.

Cabinet Construction

The cabinet is made from reinforced 3/4-inch MDF. Concealed fasteners preserve a clean appearance across the front. Its slim form also blocks less of the screen when the speaker is placed in a TV cabinet.

FAQ

Is this an active speaker?

No. It is a passive center-channel model that requires a separate amplifier or AV receiver.

Can this speaker replace a soundbar?

Not directly. It reproduces one channel in a home theater system and operates with an amplifier and the system’s other speakers.

How do I connect it to an AV receiver?

Connect speaker cable to the receiver’s center-channel speaker output. Maintain the correct positive and negative terminal polarity at both ends.

How should I set the center-channel volume?

Start with the AV receiver’s room calibration. You can then adjust the center-channel level in small increments while listening to dialogue from your usual seat.

Where is the best place to position the speaker?

Place it as close as possible to the center of the screen, usually beneath the TV. Keep the front unobstructed and aim the speaker toward the listeners.
