So... what u are saying is... most probably it won't help much on the rattling right?

Gee bro,

I dunno.. I dont tink so ..

Normally rattles caused by subs are sound pressure based so isolatin it wont make much diff.. if u r real fanatical abt it, u would hv to isolate de rattlin component n rectivy it one ting at a time..

Any photo of your setup, timothyy? Maybe too many hard surfaces for the bass to bounce around. Or simply due to the stiffness of the ceiling itself

No photo yet as my house is still a big mess.
Electrical wiring problem... then water piping problem... then all the small small thing problem...
Until now, my kitchen cabinet still not complete. HA! Ha! Moved in 1 month already.

Anyway, hopefully by Christmas everything will be in good con.

Regarding rattling... well, I guess it is normal. Since when I was in my hometown using just 2 x Tannoy floor stand, then to my JBL satellite speakers 5.1, I already have problem with rattling. Ha! Ha! Ha! Only problem is, the rattling is worst this time. But I guess this is because I have the biggest sub in my life...

Oh... by the way, I am planning to sell off my Denon Amp 2807 and speakers as well...

LOL.... Everyone needs to endure this hiccup when it comes to renovation. My home has problems too after renovation. But, minor only.

Do you have carpet to absorb the sound reflection? It could somehow reduce the vibration.

i just met up with my contractor.. seems like im going to have to renovate my house... grr was hoping to avoid this... ooh nooo~ $$$$$$

He! He! He!
Don't think you can avoid the rattling especially if you have plaster ceiling...
Even my grille also got rattling and can be heard from outside. Kakakakaka....

Anyway, I have not properly set up my speakers. So, donno la.

I believe that with proper acoustic treatment, it could be rectified.

My curtain already 3 layers. 1 Normal curtain, 1 sheer, 1 blackout.
Sofa, 1 only.
Then, the whole house empty except dining table and chair. HA! Ha! Ha!

No wonder lah. Sure got echo.

any idea how much is CHT-12R and CHT-10R now?

CHT-12R - RM2.6K
CHT-10R - RM2.0K

Rattlin cos by sub spls are very diff to tame..

I know of Southern neighbors changin windows to swing type from slidin ones cos of de rattlin - same wif sliding doors.. trick is to brace de offending rattlin part.. easier said than done thou'..

I jus liv wif it..

Cheers

Can anyone recommend a musical sub about RM1k?

Recently been thinking of doing this:

Lossless Audio on PC>Philips PSC805>Integrated Amp>Sub>Speaker.

Noob question, if i am connecting the speakers to the Sub, then that means i dont need a powerful integrated amp cause the sub is active sub? Please enlighten me.

The sound card will be upgraded to something else at a later time.

hmmm looks like better gau tim my front 1st

Kakaka... I tried to live with it but the main problem is... I worry my ceiling colapses...

Don't think you need an amp to power it anymore. Coz if your speakers connect to your sub, all the need is signal only.

Kekeke... I still have Mission speakers. Works wonderfully actually. And overall still cheap cheap.

i think putting in bass traps and acoustic panels will help a lot. the empty hard surfaces are reflecting too much sound energy especially low frequencies

you need to do something like this:

oooh ok i just read about rattling.. ehh remember ur physics? those rattling caused by resonance lerr.. everything (matter / compound) have a resonance limit one.. like in my room my window frames resonate most at 14hz i think.. my ceiling resonate most at around 17hz.

so meaning if ur ceiling rattling, it has nothing to do with ur curtains/windows because that does not effect the resonance threshold of ur ceiling.. so.. unless u treat ur ceiling properly (by finding out what exactly is causing the rattling, if its loose fitting then tighten + insulate with good shock obsorbers, and etc..

the thing about echo as mentioned by htkaki is also a cause to the rattle as the echo could be on a diff hz which may be the exact hz that creates the resonance.. so.. room treatment again very important.. avoid bare tiled floors, naked corners, shiny walls+shiny paint job, loose fittings..

and about ur thick curtains.. u have to understand that sound is not like light.. as curtain may be effective to damp light.. it may not be as effective to damp sound.. well not all spectrum of the sound.. those sound that create resonance most probably the low freq ones.. and with those sounds.. ur curtain will be audibly invisible.. u have to use proper sound obsorber, diffuser for this low/high freq.. same thing with wall cusions and wat not it may not be effective to low freq...

hmm typed too much.. should rest now.. haha im begining to enjoy Planet Drum as my goodnight sleep song hehehehe

My Planet Drum dunno sesat where already. Still haven't showed up after nearly 40 days

Anyone got new CD by S.M.V Thunder? I was at Victoria Music Amcorp and they recommend this CD for bass showcase. Maybe good to test your sub. I'm not that bass head so I'll pass. Just fyi
