Regarding the placement of sound, I hope that professional experts will talk about it.

Put all the stereos in front of the audience,

Specifically, put the left (right) surround in front of the left (right), and then put the left (right) behind the left (right) surround.

1 For most stereos, it is best to use a sound stand and then adjust it to a height roughly equal to the height of the listener sitting.

If possible, set sound-absorbing materials behind the sound to avoid the second bounce of the sound and disturb the original sound.

It is suggested that the distance between the listener and the front is more than 2 meters, and 2.5-3.5 meters is the ideal distance if conditions permit.

I recommend a stereo for you, Philips, and the scenery can be briefly described. Philips' stereo has done a good job in sound reproduction, and there is no sound dyeing. Some people don't like this, so the use of stereo varies from person to person. If it's a landscape,

A friend told me that the sound quality is not clear, not noise, but the high notes and accents are a little unclear, which is why everyone is dissatisfied with this brand. I recommend AB HIFI from bt-audio, which is a HIFI box with excellent comprehensive performance and reproduces the classic and pure English sound. Adopt super instantaneous response unit, the high tone is durable, the low tone is not sticky, the strong tone is not dry, and the weak tone is not empty. The warm and mellow timbre shows the infinite charm of music, and you can feel the charming melody of British legend, appreciate the pedigree, sound quality and workmanship.

The style contained in AB bookcase comes from the unique design of BT-audio audio engineer, a desktop HIFI speaker with bedroom and study, with exquisite and elegant appearance. First-class workmanship and sound quality have created the myth of high-end and low price in the audio industry, and completely brought the concept of parity to the extreme!

I hope my answer can help you.
