Velodyne already came with soft rubber foot. Mine sitting on marble floor but still I can't set the volume exceed 50% or every windows and glass picture frames will rattle. I think the vibration caused by sound wave and not transmitted thru the floor.

Yeah Velodyne's soft rubber foot works quite well on it's own without any additional isolating foam but 50% volume is quite high already. No doubt at high volumes the sound waves on their own can cause items to resonate and rattle but for most people, the first sign of rattling or most of their 'rattling issue' is caused by the transfer of energy and vibration through the platform that the sub is sitting on.

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 

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..

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 

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

I recently invested in a budget sub and modded it quite extensively. Its sounds a whole lot different from stock.
yes, I have plaster ceiling, I have aluminum windows and other house fixtures that can rattle. The sub is now so good it doesn't rattle anything. If it does rattle anything, its just too loud!.

hi all, newbie here..

wanna ask one question;

currently i am using pioneer AV receiver + AE speakers set + active sub.
while watching dvd (dts/dolby mode), the sub is superb.. but when listening music in stereo mode, the sub is silent.. all the bass came from the front speakers.

is my setup correct?

TQ

Set to the max la. Let ur amp control the crossover.

Unfortunately, no SVS distributor here in Malaysia. I think my_sterious has one

If its US$ price, its not exactly cheap and you still wanna consider just for side effects?.
The higher end you go on these kind of things and if you don't do something great about room acoustics, excellent spec equipment will not perform optimum or to potential. A great and expensive system in a lousy and resonant room or hall will sound shyte.

The HDMI cable from the PS3 can be used to transmit both audio and video signals.
