Auralex SubDude HD Video Review

[admin]

The SubDude HD is a platform for your subwoofer. Why would you want it? Well, a subwoofer, as you may know, generates a lot of vibration due to the fact that it puts out low frequencies and has a larger driver than most speakers. Well, these vibrations move into your floor and reduce the actual efficiency of the sub. After all, if it's expending energy into moving your furniture around the room, its not putting all of its energy potential into making sound waves. Plus it can just be a nuisance - as anyone who has experienced dishes rattling in their cupboards during a bass-heavy scene can testify.

Cool video. First time seeing one on this site.

True, it is a cool video. I just wish he would have explained what the tiny graph means and how it relates to the Sub-Dude's performance.

I mean, as I look at the graph (as tiny as it is), it appears to me that the vertical axis (okay, the Y axis) shows a loss in the sound measured in dB, and the X axis (horizontal) has key points along the frequency spectrum.

Now, I'm sure my interpretation of this chart will be wrong, but I see one of two things possibly represented on this chart:

• As you go up in frequency, the Impact STL increases, meaning that you lose dB as you go up in frequency
• OR... you see a huge drop off in dB as you move down the spectrum.

Like I said, the chart's not that clear.

I don't think the graph in this article is small enough.....

You can only see it if you are detail oriented. Everyone knows detail oriented people can see very small print. This article is clearly not for you.

Video is basically a rehash of the article(or the other-way around?). I have to agree with the previous posts, graph is way too small (even with reading glasses) and not well described (picture or graph in this case speaks a thousand words...).
Just wondering if the "value" of the stand justifies $60; looks like a pretty easy DIY (certainly compared to DIY speakers, cross-overs, amp...)

Actually, I don't have the SubDudes, but Auralex GRAMMA's under each of my Paradugm Servo 15 subs. They make a huge difference in my living room with its old wood floors.

Could you DIY these? Yeah... maybe. Honestly, though, when you can get a 4 pack of GRAMMA's (which are just about exactly the same as the SubDudes) for $143 from AValive.com, why bother making them?

Just so you know, generic foam is not acoustic foam. For the purposes of isolating a sub or instrument amp from the floor, it's pretty doubtful you're going to find foam that will work anywhere nearly as well as Auralex's.

You really can't go wrong with these things.

The explanation of how the SubDudes work in the video is incorrect. Using that explanation, you might get the impression that the SubDudes will increase your sub's efficiency.

The SubDudes do indeed decouple your sub from the floor underneath them and they do it by absorbing energy that would be transmitted into the floor by the subs feet and whatever is radiating through the bottom of the cabinet. While spikes could possibly achieve this, the SubDudes/GRAMMAs will most definitely do as good or better a job and won't press holes into your floor.

The guy in the video did an excellent job explaining how it works for people the audience it was aimed at. Whether they do a better job then spikes is debatable since there isn't a scientific study on this published anywhere that I'm aware off. I can say that from my own hearing I definitely noticed an increased in subwoofer tightness(kind of like a lowering in tuning) and less sound transmission to other rooms. Of course if I crank it it doesn't matter what is underneath the sub it will transmit. It's also much easier to move my sub and saves me from having to drill into my sub for spikes.

Some people like building things and you can certainly save money by building your own if you know what you are doing.
