Description

The Klipsch HD Home Theater Subwoofers 600 boasts a robust 10-inch driver powered by a Class D amplifier, ensuring efficient and powerful bass reproduction. The subwoofer's cabinet is crafted from high-quality MDF and features a sleek, compact design that fits easily into most rooms. The front-firing driver design helps to minimize cabinet resonance and maximize bass output. With its adjustable phase switch and low-pass crossover, users can fine-tune the subwoofer to their specific audio setup.

The subwoofer also includes an LFE/RCA input for easy connection to home theater receivers or amplifiers. Its durable construction and stylish finish make it a reliable addition to any home audio system.

NOTE: The A/V receiver/surround sound processor must be set to “Subwoofer On” and all speakers set to “small”.

The suggested crossover point is 150 Hz. If 150 Hz is not available, use 120 Hz.

Setup Guide

To set up the Klipsch HD Home Theater Subwoofers 600, 

1. Start by placing it in a corner of the room to maximize bass response. 
2. Connect the subwoofer to your home theater receiver or amplifier using an LFE/RCA cable. 
3. Adjust the phase switch to align the subwoofer's output with your main speakers for a coherent soundstage. 
4. Use the low-pass crossover to set the desired frequency range for the subwoofer, typically between 50 Hz and 150 Hz.
5. Once connected, turn on the subwoofer and adjust the volume to your preference. 

You can also calibrate the subwoofer using an auto-calibration feature available in many modern home theater receivers.

The Klipsch HD Theater 600 is a surround speaker system with 4 satellite speakers, 1 center channel speaker and 1 subwoofer. To enjoy this system, you must hook it to a separate “surround sound” Audio/Video (A/V) receiver (not included) with speaker wire and a subwoofercable (not included). Klipsch recommends the power level of the surround receiver you hook up to the HD Theater 600 is between 20-100 watts per channel. The nominal impedance of the speakers in the HD Theater 600 is 8 ohms so if the A/V receiver has an impedance selection choice, set it to 8 ohms.

• Hooking up the subwoofer to an AV receiver: Hook from the subwoofer output of an AV receiver (see receiver manual and Figure 3) to the “Left” “Line In” input on the back of the subwoofer. Use a high quality, shielded subwoofer cable for best results.
• Hooking up speakers to an AV receiver: Hook one end of dual lead speaker wire to red and black (- and +) terminals on speaker, then hook other end to corresponding (front left, front right, center, etc) red and black terminals (- and +) of the receiver (See Figure 3). Make sure to connect red speaker terminal to red receiver terminal and black speaker terminal to black receiver terminal of the same channel. Use the “dual woofer” speaker for the center channel speaker.
• Set the A/V receiver/surround sound processor speaker configuration settings to “Subwoofer On” and all speakers set to “Small”.
• The subwoofer “Level” control is factory preset at the “12 o’clock” position and, in most cases, this is the position it should be left in. The ability for additional gain on the control is provided strictly to compensate for the rare occurrence of a low subwoofer signal coming from an AV receiver. Turning it “up” may cause a signal overload (noticeable distortion) which is simply remedied by turning it back down.
• The subwoofer “Lowpass” control blends the sound of the subwoofer with the satellites and center channel speakers. It should be set to “150 Hz” on the subwoofer. Most AV receivers also have this “crossover” setting option. If your receiver does, set the receiver crossover setting to “150” Hz (120 if 150 is not available).
• The subwoofer has a three position switch labeled “On”, “Auto” or “Off”. Set to “On” the subwoofer is on all the time (Set to “Off” turns it off). Set to “Auto” the subwoofer automaticallyturns on when it senses a signal from the receiver, and automatically turns off after 20 minutes with no signal. “Auto” is the recommended position.
• The two-position “Phase” switch on the subwoofer is used to match the subwoofer’s sound with the speakers in your room. Select the position that has the most output at the main listening position.
• Although any subwoofer can be heard in an “open space’ (not next to a wall), placing the subwoofer near a wall (not against it, but with its back within 1-2 feet from a wall) will significantly increase its loudness (output), and placing it in a corner of a room on the same wall as your front channel speakers will significantly increase its output even more. When choosing your subwoofer’s location keep in mind that you will need to connect your subwoofer’s built-in amplifier to an AC outlet.

Troubleshooting

• If the subwoofer is not producing sound, check that it is properly connected to the receiver or amplifier and that the power is turned on. 
• Ensure that the volume is not muted and that the low-pass crossover is set correctly.
• If the bass seems weak or distorted, adjust the phase switch and low-pass crossover settings. 
• Also, ensure that the subwoofer is placed in an optimal location within the room.

For any electrical issues, refer to the user manual or contact Klipsch customer support. Always follow safety instructions when handling electrical equipment.
