Home Theater Network (): The following is a question about the placement of AV speakers by JBL engineers for Chinese enthusiasts. Although short, the idea of ​​determining the position and height of the speakers according to the screen is scientific. The principle applies to large Part of the home theater system.
original:
Recently renovated the house, because behind the curtain is a large floor-to-ceiling window, the speaker position is a headache. So I wrote a letter to the AV engineer of the American JBL to see the answers of Other experts, I think it makes sense. Everyone can be used as a reference. I have limited English and I hope that English speakers will give more accurate translations.
By the way, the responsibility of foreigners is really very good. I have just replied to me before simply replying and saying that I have to follow up on my question. Later, others discussed with other engineers and really gave me a very detailed answer.
1. The optimum height for the LCR is determined by the relative height of the listener to the speaker (as a side note...the face of the actors is usually about 2/3 UP from the bottom of the screen, so it makes sense to Have the tweeters on the 2/3 line from the bottom in this respect). If the speaker is mounted above the screen, and so would be above the listener, then the tweeter should be pointed at (angled down) the middle of the seating If you CAN angle the speaker down to be aimed at the center of the listening area, the statement "no more then 2 feet higher" refers to the Tweeter to Tweeter distance. Then place the L+R higher will be better. If you CANNOT angle the speaker down then place the speakers no more then 300 (thirty degrees) above the ear height.
2. The P52OWS can go on the ceiling (careful to mount it securely), 8 feet is not too high. Alternatively you can mount the REAR speakers on the SIDE WALL but BEHIND the listener locations. The SIDE speakers should be on the side wall NEXT to or slightly AHEAD of the listener locations.
According to what I understand, it is:
1. The optimal height of the left, center, and right speakers depends on the height of the listener and the speaker (Note: Usually the face of the actor is located at the bottom of the screen at the bottom 2/3 position, so the tweeter position should be placed on the screen under this rule. On the 2/3 horizontal line). If the speaker is placed at the top of the screen and also at the top of the listener, the tweeter should rotate slightly downwards, pointing to the middle of the seat area. The same applies to speakers placed vertically or horizontally. The statement that "the center should not be 2 feet (about 60 cm) above the main box" (the statement written in the manual) refers to the distance from the high to the high. If you can rotate the tweeter down, point to the middle seat area, and then hang the main box a little higher. If you cannot rotate down, the speaker should not be 30 degrees above the ear height.
2, P52OWS (JBL dipole surround) can be hung on the ceiling (note the safety of the suspension. PS: really intimate), 8 feet (about 2.4 meters) is not high. (Because my living room is behind the dining room, there is no rear wall that can only be hung on the ceiling.) Alternatively, you can hang the back surround on the side wall, but behind the listener's position. The side surround should be close to or slightly ahead of the listener's side wall. WeChat: cnhifi.
