Sub Platforms

[Irvrobinson]

Hi Guys

I have a carpeted room and have just improvised a platform to try and stop the sounds being absorbed into it by used about 4mm thick ply wood.

Should this be adequate or will the sound still be getting absorbed in to the wood as well?

Thanks

Am I missing something? I thought isolation platforms were for use on hard floors, not carpeting. If you have reasonably thick carpet with a pad underlay, why not just use ceramic tiles under the rubber feet of the sub on the carpet?

Isolation riser works no matter what type of floor you have.

Got one for $40 shipped. Be here next week. We will see if there is a big difference.

Yeah, I'd interested to hear about any improvement on carpet. (Though my sub is so big I'd have to make a platform. It won't even fit on a Great GRAMMA.)

Use two Doesn't need to fit, a little overhang does not affect performance. The only thing would be weight IMO, but I think these things are good to 300 or 400lbs.

Mine was on carpet over concrete slab and it still made a noticeable improvement.

Interesting. Weight isn't an issue, but the DD18+ is 21x26, and the way the feet are installed it needs most of that area on a platform. So, I'd need two Great Grammas. If these platforms are really such an improvement it would seem the mains could benefit too, but I'm loath to raise the height of the tweeters, which are already a couple inches above my ear height.

I admit, I'm still a skeptic about improvement of a platform on padded carpet, but I'll think about it. Maybe afterlife2 will convince me, as he did on the Roku.

 

[j_garcia]

I was skeptical that it would help on concrete too, because I felt it would be more beneficial to me on a suspended wood floor. So I was surprised when it made a very audible difference to the upper end of that sub (Adire Tempest). The Gramma made no difference with my Empire though, due to the dual opposed design. We aren't talking about a night and day difference either, but it definitely cleaned up the lower midrange, or upper end of that sub in my room.

Thanks Guy for all the advise.

I need to accept the fact I need to spend more money that I would have liked to originaly

I think it probably wise that i live with my sub directly on the floor untill i get my new sub then buy them together just in case I decide to get a bigger sub that way I don’t won’t have to spend anymore that I have to.

that's pretty much what we all here seem to live by ! LOL

Yeah if your sub is not a very good performer then an isolation platform won't work miracles for you.

You could do your research on which sub you WILL get down the road & get the size isolation platform for THAT sub to use with your current sub. As long as you don't change your mind on that future sub hahaha...

Prob best to wait!

 

[afterlife2]

Got the subdude and really like it. The bass seems to be alot tighter now. Get one.

 

[timoteo]

Glad you like it!!!

There has been some debate as to whether or not the isolation platforms actually effect the way the bass sounds in the room while your listening to it. Nobody disagrees that it helps with the transfer of bass into other rooms or other parts of the house. But some don't think it "tightens up" the bass IN the room.

When I got my first SubDude I noticed that bass in the rest of the house was lessened. Vibrations & things were not as bad or had gone away. I was happy about that. But I was also impressed with the improvement I heard setting at my seat enjoying a movie or some music. I like hearing that others notice this improvement as well...confirming im not crazy!! Well, I doubt that will ever be proven

Enjoy the tighter bass!!!

 

[j_garcia]

I don't think it tightens anything up exactly, it just makes it so you don't hear all the extra stuff vibrating that shouldn't be.

 

[timoteo]

No the platforms don't actually effect what the sub itself is producing but it helps lessen other vibrations from interfering. That is why a platform will not make a bad sub sound good but can help a good sub sound better!!

 

[Hostility]

do these platforms work for down firing subs? I should think so as the bottom platform is still attached at all 4 sides of the box which is then connected to the ground.

Sound wise I don't know if there is a difference. Maybe there is. I do live in an apartment and it was a great improvement. I had it on spikes before and the structure of the building seemed to move ( I know it sounds crazy ) almonst felt like the whole room was bending, not anymore. Friends used to tell me, I can't belive it, but I could have sworn that floor just moved. Pictures on my neighbor don't unhook anymore, so it's all good.

If there's a slight overhang on a platform is that a big deal? As an example I was looking at getting a gramma with dimensions 23"x15" and an SVS PB12-NSD that's base is 22X17. Or would I be better served upgrading to the great gramma?

Nevermind, saw this...

and decided the great gramma was the way to go.
