I'm about to receive one of these subwoofer platforms and was wondering if anyone has used one of these yet (they are pretty new). It's supposed to bring more of the sound/energy into the air as opposed to sending the sound/energy through the floor. I have a sunfire sig sub and I think the effects are going to be great, especially in my acoustically poor room.

where did you order it from? I've been seeing talks about the GRAMMA pad which were mainly used for amps and stuff. I had Auralex sent me a brochure but still has no info on how to order one. The GRAMMA cost about $50 i heard, how much is the Subdude?

The "subdude platform" is a new product so it won't be in their brochure yet. It retails for $59 but I got it cheaper from a guy on AudioGon brand new. The dimensions are 23"x15" and, while it is a little long, the width is just right for my sub. It can hold up to 300 lbs! Oh, and you can use your sub spikes too.

Sounds exactly like the Gramma. The Gramma is 23' x 15', can carry upto 300lbs and you can use your spikes on your sub with it!

I use four Gramma's, two for each Velodyne 18' sub. They are a revalation, especially on wooden floors.

I'm waiting on one too. Sub is 22"x15", so it should fit fine.

I notice also that tower speakers can be put on the Subdude. I have Def Tech towers for fronts and rears (obviously with a sub in each). Would using these under my towers and REL sub give me an improvement?


And I also would like to know how to order.

I e-mailed Auralex, who manufactures both the GRAMMA and the Subdude. They are IDENTICAL except for the color of the foam underneath and the giant logo on the top. No structural differences.


I'm using the SubDude right now, but I have not had a chance to really run the sub hard to see what kind of difference it makes.


As DMF said, sweetwater.com is a good source.

Kal,


Do you need two in most cases or are you just being safe?


thanks

I see no need for two unless the weight excedes recommended load (300lbs, iirc) or the sub is too large to be comfortable for the small platform (my case).


BTW, if you put them under tower speakers, be aware that the tweeter axis is being raised significantly.

I have an uneven floor under my subwoofer. Is the foam base of these platforms flexible enough to provide smooth coupling to my lumpy floor? Right now, the sub wobbles a bit because of the floor. I was planning in using a three-point spike system, but perhaps this is better????

Kal,


Thanks for the tip on the tweeters. Although the Auralex website and other music sites suggest it, it does not appear anyone here is familiar with actually using/hearing either the Gramma or Subdude with tower speakers in a home theatre environment (or at this point anywhere).


I assume there is a benefit because the Gramma was around long before the newly marketed Subdude. But I do not want to assume.


Anyone??

Kal,


I have Def Tech 7002's as fronts and 7006's as rears and a Rel Strata III subwoofer that I would also place on the Subdude. So as you know the Def Techs have built in subs.


Do you feel there would be an advantage with my setup which is sitting on low carpet?

Depends on what is under the carpet. If it is a live wood floor, probably.

Kal
There is wood under my carpet which are basically joists as I have a basement directly underneath.


I guess I am just trying to understand the true application of the Gramma/Subdude and how one can experience it's benefits.


Kal, what was the "good advantage" you experienced and what type of floor were your speakers on? I am all for investment if there is a practical application....

Same floor construction as yours but my sub is separate. I found SubDudes more effective on the sub but the real issue is whether one needs to prevent the speaker from directly (not acoustically) vibrating the floor boards. That's the job for the SubDudes.


Kal (who acknowledges that SOME people want the sub to move the floor)
