Wow...... This is the second case that I hear of. Do you normally listen at rather high vol?

An audiophiles who bought a PC12-NSD from me happily told me that the sub is doing its job when we were at Hi-Way Laser chatting. How? Abt a 2 feet crack appeared

Mine is about 3-4 ft crack and very visible. I like bass and the problem is some movies you don't get much of it. Other have some serious bass that really rather the whole house and you can really see the plaster ceiling taking a beating.

I have a energy saving downlight right above the sub. During those low vibration time, I can see the downlight vibrating up and down.

During Chinese New Year, I hang some lanterns on the 6 downlights in my living room and when my friend came over, i show them what my sub can do. During that time, four of the laterns drop off.

My friend who order the PC12+ with me together with the 7.1 SVS speakers just recently finish his new home and I help him setup his new system. He also mention that the HT room ceiling is vibrating too much as we can both see with powder on the floor.

That's a long crack that you have there

I never quite like plaster ceiling as it tends to vibrate easily. Mine is normal wood ceiling. My Ultra did once 'knock' down a photo frame out of the bookcase behind listening area.

Htkaki, do you think a subdude beneath the sub can help it tighten up the bass a little more?? Are we able to audition that with & without?

Any other svs owners who have more to share about the impact it cause to the surroundings.....I think it is pretty interesting to read.

yes. U r able to hear the diff with a subdude.

Best thus far wld be arj. His dad ran downstair think'g what happened when pc13-Ultra shook the 1st floor. His setup is at downstair.

How much is the subdude? Can you help to get one for me?

Posting an old pic. Do Re Mi of Auralex Great Gramma, Gramma and Subdude. Missing the premium brother SubdudeHD.

Added on March 27, 2010, 8:30 amIf getting only one subdude should be around RM290. Shipping to East should be around RM40 to RM50.
Just a rough estimate.

For the PC12-NSD with a diameter of 16", which one would you guys recommend.
My sub is located in a corner and rattles my plaster ceiling located at the rear 1/2 of my hall.
Will the isolation platform reduce or eliminate this?
Thank you.

I used Subdude for my previous PC12-Plus. It only protrude a little.

I guess it doesn't help much on the rattling but it may reduce it. Am not sure as mine aint plaster ceiling.

i have a new title to boom boom pow...PB12-Plus work out....
PS3 God of War 3...

if u thought transformers 2 was overkill wait till u getta load of this!

the subdude is not a remedy, it is meant to isolate yr subwoofer for "better" (debateable) bass production.

i have plaster ceiling at my tv area. there is a trapdoor that wud vibrate when certain sub frequencies are reached. i just take down the trapdoor, stick on some wool along all the contact points, replace it back to the ceiling, the vibration is eliminated.

Any pic to show huh?


I dun think our typical bolehland house is designed to withstand low freq wave & with plaster ceiling installed making things even worse especially you have these monster cylinders or boxes sitting inside the house & pound the surrounding like no other biz.




BTW, SVS mentions that cylinder type is their traditional way of making a sub....is that true?

Forgot to mention that the downlight right above the PC12+ already burn out twice. Not sure if its due to too much vibration or not.

Yes, SVS came out with cyclinder sub initially.

lightning69, only that particular downlight?

sorry bro, kinda cumbersome for me to climb and take down the trap door for a camera shot.

those wools, u can buy at any of the hardware shops. they are precut in rectangular/square/circle that u often use for the feet of the chairs, tables. one side is sticky tape the other is felt or woollen like material. they are cheap, about rm3 per packet. these are good remedy for contact vibration as in the case of my plaster trapdoor in the ceiling.

those with cracked plaster ceiling, are you running your sub hot & loud and by how much? just curious.

Probably due to very bare acoustic treatment. Now, I am interested to do corner trap.

Maybe you're not cranking up as high as lightning
