So am i to understand that even though my SVS PB13 ultra rests on top of concrete covered carpet, buying a gramma will yield noticeable results?

If you try it, report back. I decoupled my two PC12-NSD's from a carpet covered concrete floor and noticed NO change.

Yes most definitely, without me mentioning a thing even my wife noticed the sub now sits 2.75 inches higher off the ground. There may be noticeable results but I would think a sub rigidly anchored to a concrete slab should produce better results. Ideally you want the cone moving in and out while keeping the cabinet stationary, not the other way around.

Might be the case. I just received my Auralex GRAMMA today and tried it out. My sub is in the back corner of the room and the floor is pure concrete (stained concrete floor - no carpet). I was curious to see what would happen and I get a lot more vibration (walls, windows, etc) with the Gramma than without. I'm running an outlaw audio lfm-1 ex which is a downfiring sub. Going to do a little bit more listening but I'll probably be returning the Gramma...

I received 2 Subdudes today from Tom Lee Music in Canada. Already had one for my Subwoofer these are for my towers. Total cost $240. I tried to get the Grammas thinking I'd need them for the length of the towers but they just fit. This is for a small bedroom in an apartment my towers put out far too much low frequency sound to use without Subdudes. I can't wait to try these out!

Alright I've been reading this thread almost from the page 1 and don't see anyone talking about these moving pads. They're under $10 at Lowes or HD. I mean ok spend the $50 get the subdude, but if you're going to go the DIY route why break all the sweat buying all those materials in making one which end up costing almost as much as the subdude anyways. And they don't take up any space hardly at all like the subdude, almost invisible underneath the sub and come sizes from a nickel to coaster. When you can just pick up 4 of these things which btw come 4 in pack. As Gordon Ramsey would say...subwoofer decoupled: done!

Just get 4 rubber/foam hockey pucks and place them under the sub. The idea is to decouple. Any semi stiff absorbant material will do.

I went with these. At the the time they were $9 for a set of four EDIT: They are $7.99 now.

HA! Subjective wife input backed by measurements.

This is why I never bothered with a Subdude or Gramma. I want my cabinet to BE STILL. This is also why my mains sit on stands spiked to the floor. The speakers rest on the top platform on more spikes and Blu Tack. My mains are PLANTED.

Unfortunately in a double blind test she failed miserably so guess it wasn't so, sigh.

I purchased a great gramma to isolate my Ultra 13 which sits in the rear of my room on the riser that wasn't damped properly, there's no question the unit works for isolating mechanical energy from the surrounding structure but these two wrongs make a right in a very compromised way. Actually the sub directly on the riser kind of acts as a one of those seat vibrator devices, the effect offers more positives to the viewing experience than negative.

I didn't feel like spending $50, so I headed over to Lowes and bought these:

http://www.lowes.com/pd_235483-255-4...0051&langId=-1

I placed the carpeted side down and there's a dimple that allows me to center the spikes perfectly.

In my case (pair of HSU VT2-MK3's), the spikes had poked through my thick carpeting and padding and there was only 1/2" space between the floor and the downward firing driver. (too little)

The Caster Cups allow the full 2 inch gap and also isolate the floor, so no noises from direct contact with the floor.

Im looking at getting a new sub. Problem is I live in an apartment on second floor. How do these things perform in not bothering my 70 year old neighbor downstairs?

Well I also live on the second floor in apartment - and I got my first sub two months ago - and a subdude one month ago. I've not gotten any complaints - but I know my up- and downstairs neighbour can hear it. The deep bass is hard to stop travelling all over, but the subdud did certainly help the bass from causing the wooden floor to vibrate along with sub - it really does (in my case) decouple the sub from the floor - which helps a lot.

Do you get complaints now?

I was only really considering one of these because my soon-to-arrive Captivator has NO feet at all and I'd rather not place its finished oak bottom on my bare hardwood floor and risk damaging either.

Well, after reading a large sum of 50/50 reactions to it on this very thread, there's no way I'll be spending 50-$100 on one which is absolutely absurd to begin with, IMO.

I constructed a riser with a nicely padded base and rubber feet for under $20, so anyone who thinks they'll end up spending as much as a subdude constructing their own must be shopping at some strange hardware stores. Surely my version has to rival this thing from an isolation standpoint and I KNOW it's a 100% improvement, aesthetically. I'll post a pic w/materials if anyone's interested.

I found a solution to this problem. I recently purchased dual 18" subs. These were shaking the heck out of my house. Walls, kitchen cabinets, doors, you name it.

Now they are sitting on 16x16x1 inch rubber deck tiles for isolation. They fit far enough under the 20x20x20 enclosures that they are not visible. The tiles are made of recycled tires and used outdoors on wooden decking to dampen footfalls.

I got them for $5 each at a hardware store. It GREATLY reduced the transmission of energy from the suspended floor to the walls, and the subs enclosures are planted, they can not move.

Probably the best tweak I have ever discovered, cleaned everything up and I can even hear my mains better. Neighbors don't hear me as much, either. Put simply, they work.

I did lose that some of that visceral thump that comes up from the floor. I do miss it but I gained so much more.

It is pretty cool when you can make your hardwood floor ripple, but is it accurate? Probably not but it sure is fun to see peoples' faces when they feel the floor move under their feet.

No i dont get complaints but thats due to not having a sub at the moment.

Then just go for it (with a subdude - or something like it) - remember there's a big difference between being unconsidered and wanting something for your own sake - just don't watch Tron or War of the Worlds to late (on a weekday). You have to be able to have a life - even though you live in an apartment.

Here's my solution, sorry for the iphone pics, I'll try to post improved ones later.

Mine is slightly "undersized" in relation to the depth and width of the sub as I wanted to create a stealth, "floating" look once it's atop of the base. I'm stacked 300+lbs on it with nary a creak or disturbance.

The base lengths/rails are composed of 1 1/2 square stock poplar with a 2" center block for added stability. The top is a piece of 3/4 laminated pine. You could use oak or whatever you like, but I was painting mine black anyway and have found a small piece of lam pine to be amply strong when properly supported. All this, nevermind the fact that you hardly see it anyway once the sub is mounted.

The pads atop are much more rigid/susbtantial than they appear. Then I also have plastic threaded inserts tapped into the poplar base that further isolates resonation.

The adjustable steel feet have "glider" caps that finish the damping and also work amazingly well sliding it around like it's on ice.

$20.

I have someone using a bedroom that is in a different unit than mine and directly under my living room where my sub is. It is an old building that was originally a school that was converted into condos. My DSP-3400 is 19x16 (20x16 w/grill) Im guessing that the subdude will solve that problem...hopefully. Do you think I could get away with one subdued to fit under it without it tipping.

And is there a significant compliance somewhere to actually provide some isolation?

Besides the 1/2" foam pads, plastic inserts and rubber feet? No.

But try as I might, I could not discern a difference between it and a friend's borrowed subdude.

Thanks, I realize it doesn't appear to be nearly "spongy" enough to be effective, but after REALLY over building (read soft-city) two others I found that the "secret" is putting together a rigid platform and implementing just enough absorbtion here and there.

And the ability to slide it around like it's on glass is nice with my 200+lb monster.

The Subdude is 15"x15" - so if the subs feet can stand on it - you're safe - if not look at the Auralex Gramma, which is 23" long x 15" wide (it's the same product in different dimensions).
I'm not sure it will solve all you're problems, if there currently is a situation with you're the neighbours downstairs - but if not, it should improve decoupling of the sub - and then less vibrations to the floor, which helps alot (it did in my appartment.

I guess I'm too late to answer this, but I've been using a subdude with my Epik Valor for almost three years now with no problems. The base measurements of the Valor are about 22" x 16.5" so it's quite a bit bigger than the subdude but like I said, I've had no problems and actually I prefer that to having a gramma sticking out from the sides. With mine you don't even see the subdude.
