Frequently Asked Questions - ERS 210 II INFINITY
How do I properly position the Infinity ERS 210 II speakers for optimal sound?
Place the speakers on sturdy stands at ear height, about 6-8 inches from the rear wall to avoid bass boom. Angle them slightly toward the listening position for better imaging.
Can I use these speakers with a low-powered amplifier?
Yes, the ERS 210 II has a sensitivity of 90 dB and requires only 20 watts minimum. However, for dynamic range, use an amplifier rated between 20-100 watts RMS.
What is the recommended break-in period for the ERS 210 II?
Allow 20-40 hours of moderate playback to loosen the suspension components. The sound will become smoother and more detailed over time.
How do I clean the speaker grilles?
Gently remove the grille by pulling from the corners. Vacuum with a soft brush attachment or wash with mild soap and water. Let air dry completely before reattaching.
Can I bi-wire or bi-amp the ERS 210 II?
Yes, the speakers have dual binding posts. For bi-wiring, remove the metal jumpers and connect separate cables to the woofer and tweeter terminals. For bi-amping, use two amplifiers.
What is the correct impedance setting for my receiver?
The ERS 210 II is 8 ohms nominal. Set your receiver or amplifier to the 8-ohm setting, unless it auto-detects.
Why is there no sound coming from one speaker?
Check speaker wire connections at both ends. Ensure the amplifier is not in mono or bridged mode. Swap the speaker cable to the other channels to isolate the issue.
How can I prevent damage to the speakers when playing loudly?
Avoid amplifying distortion. Keep the amplifier below clipping. Use a high-pass filter if subwoofer is present to reduce excursion.
Are replacement parts available for the ERS 210 II?
Yes, you can find replacement woofers, tweeters, and crossover networks from authorized Infinity dealers or online parts retailers.
What should I do if the speaker sounds harsh or distorted?
Check for debris near the driver. Verify that the grille is not vibrating. Ensure the amplifier is not overdriven. If persistent, the tweeter might be damaged.Replace with original Infinity parts.
