Frequently Asked Questions - SM-40 Chord
How do I connect the Chord SM-40 speakers to my amplifier?
Use standard speaker wire with banana plugs or bare wire. Connect the red terminal to the positive output and the black terminal to the negative output on both the amplifier and the speaker. Ensure a secure connection to avoid signal loss.
What is the recommended placement for optimal sound quality?
Place the speakers on sturdy stands or bookshelves at ear level. Keep them at least 20 cm away from walls to reduce bass boom and ensure the tweeters are aimed towards the listening position for a balanced soundstage.
Can I use the SM-40 with a subwoofer?
Yes, the SM-40 can be paired with a subwoofer. Connect the speaker terminals to your amplifier normally, and use the subwoofer output from your receiver if available, or connect the subwoofer in parallel, ensuring the impedance load remains within your amplifier's limits.
How should I clean the speaker cabinets?
Use a soft, lint-free cloth slightly dampened with water to wipe the cabinet. Do not use alcohol, ammonia, or other solvents as they may damage the finish. Avoid spraying any liquid directly onto the speaker.
What cable gauge should I use for connecting the speakers?
For distances up to 10 metres, use 16 AWG or thicker wire. For longer runs, 14 AWG or 12 AWG is recommended to minimize resistance and preserve audio quality.
Are the SM-40 speakers magnetically shielded?
Yes, the SM-40 speakers are magnetically shielded. This allows them to be placed near CRT televisions or computer monitors without causing color distortion, though it is still advisable to keep a short distance for best performance.
What is the power handling of the SM-40?
The SM-40 handles up to 40 W RMS and can peak at higher levels. For safe operation, matching them with an amplifier rated between 10 and 50 W per channel is recommended, as overdriving can damage the drivers.
Can I use the SM-40 as a center channel speaker?
Yes, the SM-40 can be used as a center channel. Its shielded design and balanced frequency response make it suitable for dialogue reproduction. However, ensure that it is placed horizontally or vertically according to the available space, and maintain proper toe-in.
Why is there no sound coming from my SM-40 speakers?
First check the amplifier is on and not muted. Verify that the speaker wires are securely connected to both the amplifier and the speaker terminals. Test with another pair of speakers to rule out amplifier issues. If still no sound, inspect the speaker terminals for damage and ensure the impedance is set correctly.
How do I obtain spare parts or repair for my SM-40?
Contact the retailer or an authorized Chord service center for genuine spare parts such as drivers or crossovers. Do not attempt to disassemble the speaker yourself, as this may void the warranty and damage internal components.
