有人追求極致聲音的重現, 但也有人僅要求外觀及聲音間取得平衡即可...
不是每個人都開得起雙B, 甚至是Porsch, Ferrari, Lamborghini...
但是只要符合自己需求的, 國產小車也會讓人使用得很開心..
Hi, there
Sorry about the English message, I am in the office, no Chinese fonts.
Anyhow. You can take a look at this tread regarding to your question about the Bose system.
"How Do I Beat Bose??"
http://www.avsforum.com/avs-vb/showthread.php?t=1101462
It's really hard to match the small size of the Bose system. But in the speaker's world, size does matter. Here is one forum member wrote about Bose:

"To reiterate the above, the Acoustimass's bass module responds to 46 Hz to 202 Hz at ±2.3 dB, while the satellites respond to 280 Hz to 13.3 KHz at ±10.5 dB. This is, by the way, the only speaker that I have ever seen tested with a ±10.5 db allowance. Still, this leaves a frequency gap between the satellites and bass module of about 80 Hz! That is 80 hertz of sound that is completely erased within the system's internal crossovers! I wonder how Bose figured out which 80 hertz matters least in the audible spectrum? I will tell you though that that gap accounts for a HUGE loss in midrange sound, which is responsible for the majority contralto, baritone, and tenor vocals in music, and many sound effects in home theater. And let us not forget that the Acoustimass system also ignores audible signal from 20Hz to 45Hz on the low end (deep bass), and 13KHz to 20KHz on the high end (high treble). Do the math folks, this Bose system only produces 13,176 of the 19,980 Hertz in the audible sound spectrum. That's only ~66% of the actual recording being played back to you! Is this the kind of performance you'd expect from a $1300 product? Most speakers in the same price range are able to respond from 15 Hz to 25 Khz and all modern media formats, from vinyls to DVD, record these frequencies as well. Though these are peak frequencies that most humans can not hear, the pressure produced from 15 Hz and 25 KHz frequencies can be detected physiologically, and will in fact have an effect on the harmonics of the music you listen to. So why does this "industry-leading" Bose company only produce about 52% of the sound of it's equal-priced market competitors? Good question..."

Since you are in US, AVSForum might help you a little bit more. Especially the brands and models are a little bit different than in TW. Most people in the forum are nice, helpful and knowledgeable. Again, if you did buy the Bose system cause Wifes always wins. Don't listen to other people's system and ask for the price. You might not be a happy person afterwards.
Anyhow. happy new year.

Hi,
Thanks very much for your comments and weblink. I'll be sure to start looking into the avsforum for more reviews on Bose and other competing surround sound speaker systems.
Because of the pre-wiring done by our builder, we can only opt for external speakers hung from the ceiling or in-ceiling speakers. In-ceiling costs too much, as the installation alone would be at least $800, which then doesn't leave us with much budget for a decent system. Thus we have little choice but to look for system with as-small-as-possible satellite speakers.
I completely understand your points and have also suspected that Bose's demo room is purposely set up to hide the deficiencies of its speakers. However we still can't explain why Bose sounds so pure and clean, while many other systems we listened to (including our old Sony 5.1 and Logitech Z-5500), in comparison, sound muffled and hissed. Maybe it's because of the mid-range that Bose left out.
Many people in this forum got the wrong impression that my wife WANTS Bose. But that's not true. She really likes the sound that she heard from Bose but also admits that Bose is very pricey. She believes that without the name "Bose", we should be able to get comparable, or even slightly better, system at 20% discount or more. Now the challenge is to find such 6.1 system with small white satellite speakers in about $1,000 price range that we both feels that is as good as Bose.
Thanks again for your comments and I really appreciate the time you took to respond to me. I'm glad that I joined mobile01, as there are so many good folks like yourself willing to share your comments and thoughts with newbies like me.

就補充一下
事先說明不是針對BOSE
而是小的衛星音箱的難題
喇吧發聲原理是推動空氣
沒有空氣就沒有聲音
音箱需要推動大量的空氣而產生低頻
一般來說所以小的喇叭無法推動這樣多的空氣
所以重低音大多數體積很大
這是基本的物理難題
可是為了美觀等的需要
於是BOSE這家有深厚基礎的廠家開創了風氣先河
用幾乎是微型的幾個衛星喇叭負責中高頻的部分
而所有的低頻統一由一個比較大的低音負責
因為根據某些研究
超過一定的界限低頻是沒有指向性的
沒有必要每個喇叭都去負責所有的頻率
一般來說以80Hz以下為分頻點
(就是說擺哪都無所謂)
PS這跟空間也有關
這也影響了以後 5.1的規格
所以這樣的成就等於是BOSE被肯定的
可是成功的背後還是有些物理的難題為解
就是音箱小到一個程度連80Hz都無法達到
於是另一項妥協是為了這些做不到80Hz低頻的喇吧
後來的AV擴大允許把分頻點提高到100Hz以上
可惜的是BOSE這類的衛星不要說80HZ作不到連100HZ，120HZ都沒有辦法
因為它們實在太小了
所以"早期的"BOSE想到了一招後來其實有不少廠家抄襲的方法
就是把分頻的工作轉到他們的低音上去處理
先將所有的聲道輸出道低音模組上去
避開了AV擴大機的低音處理
然後由BOSE的低音模組中的低頻管理器過濾後再送到衛星喇叭上去
分頻點是哪，小弟手邊沒有資料
但很顯然分頻點應該不是80Hz
不然就不用多此一舉了
(另一種是用自家的all-in-one,可是義意一樣)
-----待續
樓主的目標Acoustimass 16不是這樣
後面會解釋
打的很快可能有錯
僅供参考
第一 低音模組不但要負責低頻的部分，還要擔任一部分的中頻，
如何設計出橫跨這麼大範圍頻率的低音同時兼具速度和音質
所以可能必須犧牲掉一部分範圍的低音
第二 指向性的問題，80Hz附近以下聽不出位置沒關係，可是200HZ以上說不過去
於是產生了一個問題就是
一個聲音會有兩個位置
一個是衛星喇叭發出的，一個是低音模組
這樣的音場會很怪異
可是樓主提到Acoustimass 16不是這樣
而是如普通的5.1一般
並未通過低音模組
可是這意味低音只負責80Hz-120Hz以下
而微型的衛星喇叭必須有最少低到80H-120Hz的實力
這是非常非常困難的
不然的話雖然沒有以上的兩問題
可是有一大部分的頻率都不見了
不過也有可能靠著BOSE的超高技術可以達到
是小弟聽錯了
------------------------------------------------
以上是不負責的討論
不見的是事實
僅供參考
說不定是小弟誤寫或誤解了
請鞭小力一點
但這樣對我來説"代誌都大條"了。以下照片是跟我新家一模一樣的另一間房屋的客廳：
客廳部分約17'x17'，8坪左右。中間的凹槽就是視聽裝備的預留空間，我會請人做架子。建商内置的低音綫會隱藏在右邊的墻腳。綫路是一般的。如果要裝Bose就很麻煩。可以將Bose的低音炮裝在中間，TV下面。但這樣會很不好看，而且Bose建議低音炮離TV至少要有0.6公尺的距離。
以下是小弟自己用簡單的軟軆畫的視聽架意識圖：
凹槽的上面會做置物柜，下面放A/V器材，中間自然就是電視。電視準備買平價的52寸LCD。擴大機會是Denon AVR-789 或 AVR-1909，兩款都有HD Audio並可以up-convert analog signals。HD電影部分打算請人拼湊一台有藍光機的HTPC，這樣可以看藍光電影或自行下載HD電影。這台HTPC也將會是家中所有影音圖檔的儲庫。此外，我還有一台Epson EMP-TW600的家庭投影機，已經請建商在客廳尾端的中間部位内置綫路。屆時再去Best Buy買電動遙控120寸銀幕，請人裝上。
現在看來Bose必須出局(除非我願意多花錢做綫路隱藏...我不願意)。家庭劇院的音箱部分必須重新規劃。雖然我不喜歡東拼西湊，但現在看來只有如此。我準備找一套5衛星音箱系統，如下：
http://www.bestbuy.com/site/olspage.jsp?skuId=9015157&type=product&id=1218008591509
當然要找到白色的，並能現場試聼，裝在front left/right, rear left/right & rear center。Front center打算買一個$200左右的中置音箱，放在電視正下面的A/V架子。因爲我愛看電影，電影對白的音質對我來説挺重要的。低音部分則打算用現有Sony 5.1的低音炮。我和老婆對低音方面都要求不高，只要能轟隆達拉的有震撼效果就可以了。
不含現有的投影機與Sony低音炮，A/V繌預選以不超過$4,500為原則，包含稅與安裝費。大概分配如下：
52寸電視 ------ $1,500
HTPC ---------- $800
Denon 擴大機 --- $500
5.0衛星音箱系統--$600
中置音箱 ----------$200
電動遙控銀幕 -----$450
總安裝費用 -------$400
還請各位大大繼續給予建言與指教。謝謝！！！
