[#1] 家庭影院-重新開始    
小弟因為搬屋,有機會重新開始建位家庭影院。
小弟以前有部天龍3808a + MK (L/ C/ R/ sub) + mirage nanosat 玩5.1。
因為新屋都係梳化貼牆,今時今日仲玩5.1係咪好on 居?
另外,請問各位有冇外國網站買後置喇叭缐平d呢?
新屋擺位如圖,電視牆背與梳化後牆距離約116吋。

玩盡是 5.1.4 丶再加front high, front wide, 即是 9.1.4

如果女主人不同意,小型喇叭座,就不能玩front wide!

好多新amp 都有

Atmos , 兩個 在廰中,兩個在 頭上前 少少丶全部要同前 左右同一缐

後置最好去到70hz, 因THX requirement 是80Hz, 再低10hz, 安全D, 好聲D丶因 好多 小喇叭 低音位 會落數db, 如run room tune 谷大到平直丶會好傷!

樓主 的nanosat 只去到110hz, 可保留作front high.

OS3 可去到 70hz

From google

Quote:
Research in human hearing shows that we can hear many more directions than what current systems provide. We use the direct sound to localize the direction of sources and the reflected sound to perceive the size of the soundstage.

Experiments have shown that human localization is better in front than to the sides or behind. This means that for front-weighted content such as movies and most music, good engineering dictates that we employ more channels in the front hemisphere than the back. Imaging is also better horizontally than vertically and so good engineering also dictates that channels must first be added in the same plane as our ears before going to higher elevations.

Perception is not the only factor. The physics of room acoustics for music have been well studied, and their correlation with subjective impression increasingly understood over the last 30 years. This research has shown that we have strong built-in preferences for the direction, frequency response, and time of arrival of reflected sound. Additional channels and surround sound processing are needed to properly render these components.

Wides before Heights
One key finding from the research is that first side wall reflections play a great role in determining subjective impression. The most important direction of reflected sound was found to be ±60° relative to the front. Audyssey DSX provides a pair of Wide channels (LW and RW) at ±60° with appropriate frequency response and perceptual processing to match these requirements of human hearing. These Wide channels are much more critical in the presentation of a realistic soundstage than the Back Surround channels found in traditional 7.1 systems. Adding surround channels behind the listener has a very small impact compared to the increase in envelopment and soundstage width that the Wide channels provide.

The next most important acoustical and perceptual cues come from reflections above the front stage. Audyssey DSX provides a pair of Height channels (LH and RH) that should be ideally positioned at a 45° elevation angle.
