This tutorial provides practical guidance on using WiiM's Room Correction feature to optimize sound quality, based on valuable tips shared in a WiiM forum user's post. These practical tips make it easier and more effective to use Room Correction for achieving optimal sound performance.
1. Place Your Speakers and Subwoofer
- Speakers Placement
Place them close to the wall behind. If they have a bass-reflex port, leave about a 5 cm gap. This shifts the primary SBIR cancellation to a higher, less noticeable frequency. - Subwoofer Placement
Position it in a room corner. This increases bass output through boundary reinforcement, giving extra headroom for later room correction fine-tuning.
For the rationale behind these placement choices, please refer to this article.
2. Set Up Your Subwoofer
Subwoofer Crossover Frequency
Set the subwoofer crossover frequency typically to 80 Hz.It's ideal if you can measure the in-room response with Room EQ Wizard to fine-tune the crossover. If not, you should still be able to achieve solid results by ear.
Subwoofer Level
Adjust the subwoofer level so it matches the loudspeakers. It’s fine if the sub sounds slightly louder at this stage, as room correction will balance it later.
3. Synchronize Speaker and Subwoofer Delays
Use the automatic Subwoofer & Speakers Sync function in the WiiM Home app to calibrate the relative delays between the speakers and the subwoofer. For detailed instructions, see Tutorial: Syncing Your Subwoofer with Main Speakers.
4. Configure the Room Correction Settings
Refer to the screenshot or table below for the recommended configuration for each Room Correction setting:
Settings | Recommended Configuration | Descriptions |
|---|---|---|
| Target Curve | B&K | |
| Freq | 20-400 Hz | If your subwoofer does not reach 20 Hz, use the lower frequency limit specified in the subwoofer’s specification sheet instead. |
| Max Gain | 12 dB | The max gain controls for positive and negative gain will be separated soon. After that, set the max positive gain below 3 dB (preferably 0 dB) and the max negative gain to 12 dB. |
| Max Q | Use 10 (default value) if no EQ boosts or positive filters are applied. Set it to 5 if you want to be more conservative. | Using 5 will make the adjustments less precise in reducing resonance peaks. |
| Smoothing | 1/12 octave | |
| Subwoofer Calibration | Enable if using a subwoofer | |
| Multiple Measurements | Enable | Move the microphone slightly between attempts for spatial averaging. |
| Precision Room Correction | Disable | It is not recommended in most cases. |
| Import a Calibration File | Yes (if you have an externally calibrated measurement microphone) | For details, see Tutorial: Microphone Calibration File Import in WiiM Home. |
5. Perform Room Correction
Start the Room Correction process in the WiiM Home app and follow the on-screen instructions to complete it. For detailed steps, see Optimizing Your Audio Experience: A Comprehensive Guide to Room Correction.
By following these clear steps and explanations, you can achieve more accurate and effective room correction, resulting in optimal sound performance.
