In this video, we will discuss how low frequencies can be affected when a loudspeaker is placed up against a hard surface. We will also show you how to use a high pass filter to tame these low frequencies.
Here are the key points from the video:
- Low frequencies below 400 Hz are omnidirectional, meaning they radiate in all directions equally.
- When a loudspeaker is placed up against a solid surface, the low frequencies can reflect off of the surface and then sum back with themselves, creating a significant level increase in the front.
- This increase can be up to 18 dB if the loudspeaker is in a corner against three solid surfaces.
- To avoid this, you can use a high pass filter to reduce the amount of low frequency energy that is produced by the loudspeaker.
- You can also use your ears to reduce the bass level until the sound is clear and punchy.
Here are some additional tips for loudspeaker placement:
- Place your loudspeakers away from walls and corners.
- Use speaker stands or tripods to elevate your loudspeakers.
- Experiment with different placement positions to find the best sound for your room.
By following these tips, you can ensure that your loudspeakers are placed correctly and that you are getting the best possible sound quality.
