"""d bass 靚唔靚同後級power冇關係."""

yep, more about slew rate and damping factor which affect the quality and quantity of bass.

"地方細可能仲要用大力後級, d bass 會 tight 好多. 細力後級d bass 會 bloated, boom 到七彩"

大力後級bass 唔一定靚. 細力後級d bass 唔一定差.
d bass 靚唔靚同後級power冇關係.

"""Can we design speakers that are meant to be installed on a bookshelf and still sound decently? Of course we can.
The boost in the bass and mid-bass range can be calculated a priori (approximately, of course) and kept into consideration when designing the loudspeaker. Just make it a little bit bass shy in free air, so that it'll become linear when placed close to the rear wall. Linn and Naim speakers used to be designed this way."""

there are many olden days speakers designed to be placed against front wall. the kef kube can make adjustments too like an equalizer.

there are some modern speakers with adjustments to low frequencies such as gryphon cantata, focal utopia scala etc.

"""地方細可能仲要用大力後級, d bass 會 tight 好多. 細力後級d bass 會 bloated, boom 到七彩"""

even small amplifiers can output 20 to 20khz flat within 10w. can u give us some examples to substantiate your claims?

只好找一些不是後氣孔設計的喇叭.＞＞＞＞＞
都係一個比較簡單可取的選擇.我依家用緊kef 104ab, harbeth p3esr, linn 109, 都唔係後出氣, 離後牆都不足一尺, 用在細地方比較容易處理.

toe in affects the intensity of on and off axis high frequencies, not much effect on low frequencies. so why toe in can correct booming?

"不如換speaker啦, 呢個方法畢竟算係比較直接~"
Totally agree! I've ever used a lot of methods to reduce the bass of my previous speaker FS788 but only got a little improvement. After changed to ProAc response D one, I found there is at lease 20% improvement of the high extension with better quality of bass. (This result is only for my listening area where is about 140 sq feets)

以我所知係可以用軟件改, 由於係透過計算修正, 效果頗為明顯, 但條件係你要改用電腦播歌~

不如換speaker啦, 呢個方法畢竟算係比較直接~
