just tighten the screws affixing the drivers.

this should be done every 6 months.

"""喇叭背出氣孔已塞綿條"""

i cannot see how this is acceptable. your speakers are designed as bass reflex and blocking the air vent will augment the frequency response and behaviour of the mid/bass drivers.

time to change the speakers.

麻石 can be ordered from building material shops at Portland Street [near Bute Street], Mongkok or Lockhart Rd, Wan chai.

Also buy Sanrubber mat 9mm thick 455 x 910 mm from Hings shops to place under the 麻石. See links below :

Sanrubber info : "http://www.hingsgroup.com/productMidSize.aspx?p=516_Hings+Safety+Ref_W-32.jpg

Shop locations : "http://www.hingsgroup.com/net_hk.aspx"

Sanrubber is actually made for use under wooden floor at dancing hall/school to absorb vibration & sound transmission. It is very effective for vibration damping. I have been using it under my cdp & speaker spike plates. Many friends do the same at my recommendation & all are very happy about the improvement. Price several years ago was $200 when I first bought it. Last time the price was $300 when I bought again a couple years ago. It does not cost you an arm or a leg so it is worth to try.

If you cannot use good speaker stands due to space constraint & have to place the speakers on top of low cabinet, then spikes + 麻石 + Sanrubber is the next best solution.

Black 麻石 should be better than other colors or 雲石 because it has the highest density of all.

>>>>I feeling booming , how to improve as my right speaker 近長角那隻比起不近那底頻重好多!!因此右邊果隻氣孔要塞綿才get balance !!

look at orchestra double bass almost always on the right hand side. dont think u can localize sub bass as it is non directional. mostly u have problem with bass in the range of 100-500hz. perhaps if u use equalizer or some form of room acoustic treatments?

不要塞氣孔,共震同低音太勁係錯覺,應該係撞牆反射番嚟1+1=2嘅假太勁低音,另那些是諧震distortion 扭曲; 變形; 失真,不是共震。要攪吸音化震了。牆角吸音,腳架化震=舒服晒。雲石板唔及炭纖板又唔及腳架注沙咁化震。

If your cdp is placed on same cabinet top with speakers, you must damp the vibration at cdp & speakers with good materials like spikes + Sanrubber + black 麻石. If you don't solve the vibration problem, all the money you spend on replacing the gears is wasted & you still cannot get any improvement. Spending a little money to try vibration-damping should be the first step.

Of course, position of speakers is also very important in producing good sound.

其實何解cdp都要墊東西?
我昨天都去買了塊sanrubber 9mm,現在要$360/塊。還訂了兩塊高密度麻石,下星期二到取。它們是用來墊喇叭的。因為我都有同樣問題,希望可以解決。

If your cdp is placed on same cabinet top with speakers, the vibration generated from the speakers will transmit to the cdp through the cabinet. The laser head has to read the extremely narrow tracks so that any small vibration will affect its performance.

Placing spikes [with disc plates] + 麻石 + Sanrubber under the speakers will prevent [or at least minimise] transmission of vibration to the cabinet top & cdp. Doing the same for cdp will prevent transmission of vibration [if there is still any left after damping that from speakers] from cabinet to cdp. This is like a double insurance.

One piece of Sanrubber should be enough for a pair of small speakers plus cdp. So there is no extra cost except cost of a piece of black 麻石 for cdp.
