Auralex SubDude-II™

D. from Alhambra, CA on 7/18/2018

Crutchfield Customer Review (What's this?)

I was skeptical of the benefits this product claimed but was intrigued by the positive reviews. Gave it a try for a good price, a small price relative to the B&W DB1 sub it's supporting. A notificable improvement with tighter, refined bass all around. The floor still rumbles at high volumes but bass definition is better. Getting more enjoyment out of action Blu-rays. Unexpectedly, it also looks great showcasing the sub. Strongly recommended for audiophiles. With Crutchfield's satisfaction promise, doesn't hurt to try.

Pros: Nice improvement on sub with fair price.

Cons:

Cleaner results on your sub and environment

Adam from Lynnwood, WA on 6/27/2018

Crutchfield Customer Review (What's this?)

If you need this, you'll love it. Will it fix everything? No. A sub causes rapid vibrations and sonic frequencies that at higher volume makes things vibrate. But it will reduce the vibration and unintended noises caused by those vibrations transferring to floors. When my sub is really loud, there are still vibrations felt, but they feel softer and less hard on the floors. Especially if using a sub facing down, which causes the harshest vibrations. But I'm also talking about when you are pushing a sub at a pretty decent dB rating for the room (rememeber watts don't equal volume). Unintended benefit was by moving my sub a little (to a position I previously did not like due to the muddying of sound), it sounds really clean. Sure, I lost some volume by not having the floor react to the sub, but it now sounds like clean bass. Just remember some of the bass perceived volume is not just coming from the driver.

Pros: Cleaner sound from the sub Less vibrations overall, noticeably Looks really nice

Cons: Pricey depending on your setup Doesn't remove all vibrations (that was expected)

Works well

NeoTheOne from Elk Grove, CA on 6/5/2018

Crutchfield Customer Review (What's this?)

I purchased this for my Klipsch R110SW sub and all I have to say is WOW! The SubDude drastically reduced my windows, blinds, pictures on the wall and shelves from rattling. Because of this the bass sounds a lot clearer. It worked so well in the house I decided to try it in my car for my 12" woofer, man it cleared about 90% of all the rattles in the car, I love this thing!

Pros: Reduces vibrations and is constructed well.

Cons: I think it is a bit too pricey.

This platform made an immediate difference; took the floor and walls out of the mix and the sub (ELAC S10) produced the tight clean bass it was capable of.

Pros: Simple solution that worked as intended.

Crutchfield Customer Review (What's this?)

I immediately heard an improvement in sound quality and a reduction in window vibration. The speaker is behind a chair in a corner with windows directly above it on both walls. The windows still rattle, but it takes more volume than we typically listen at. A big improvement.

Worth Every Penny

Thomas from Dallas, TX on 2/23/2018

Crutchfield Customer Review (What's this?)

These SubDude-IIs work as advertised. My home's A/V setup is in a room with hardwood floors and wood paneled walls, floor to ceiling. Great acoustics, but the vibration issues associate with the 7.2 system's subwoofers were severe even at ordinary volume levels. As promised, these bad boys disengaged the subs from the floor and the improvement in overall sound clarity and quality is, simply stated, phenomenal. Call it addition by subtraction if you want, but with the vibration and attendant audio roar associated with it eliminated the audio image now is crystal clear throughout the audible spectrum. Worth every penny.

Pros: They perform as exactly as advertised. Easy to set up (all you have to do is put them under the SWs and center them).

Cons: None

Most effective acoustical treatment

Ed from Cynthiana, KY on 12/13/2017

Crutchfield Customer Review (What's this?)

I built a home theater, or some would call it a media room because I don't have a projection television, about a year ago. It's not a large room at 12' by 16' by 8' ceiling and has engineered hardwood flooring. I have 2 each 12" powered subwoofers which some would call an overkill; personally I subscribe to the theory that there is no such thing as overkill. Obviously low frequency management was an issue. The hardwood floor became the first and closest reflection point in the room. I have learned the hard (and expensive) way that there are a lot of "snake oil" acoustical treatments on the market including "acoustical paint"! The SubDude-II made an instant and audible difference. I would rate these as the best acoustical treatment I've bought, they don't reduce the bass, just makes the bass cleaner by helping control the low frequency reflections. My test was some jazz music with an upright bass, you can hear the musician's fingers sliding up and down the strings and still get rich deep bass you would expect.. If you happen to have a down-firing subwoofer I believe these will be even more effective.

Pros: Reasonable price, work as advertised, not visually unpleasant

Cons: None I can think of

Auralex SubDude-II subwoofer isolation platform

Anonymous from Denver, CO on 10/14/2017

Crutchfield Customer Review (What's this?)

It's pretty simple, really. It's a piece of 3/4" MDF wrapped in felt with a piece of foam glued to the bottom. Seriously, that's exactly what it is. Should it be at this price? No. It didn't make a huge difference to my ear in terms of sound quality with my REL T7i sub. I did notice a slight decrease in output level, actually, but that was easily rectified by turning up the sub a bit. I really only got it because my old house has very flexy floors where the sub sits and when playing very deep bass at high levels, the sub would start coupling with the floor and jump up and down and scoot around the floor. This solved that problem completely, so it gets a passing grade.

Michael from Hilo, HI on 8/6/2017

Crutchfield Customer Review (What's this?)

Bought this as no matter the placement of a custom 13 year old 100 pound plus sub did not yield the bass I thought I should be hearing. After placement of the SubDude-2 I couldn't believe the difference. What I thought was decent bass, was in fact muddied bass tones, compared to the clean hard hitting bass I am now hearing. I am not an audiophile, but I know what I like. Mikey LIKE !!

Cons:

Improve your sub bass with little cost. No downside!

Michael from Annapolis, MD on 7/30/2017

Crutchfield Customer Review (What's this?)

This is one of the cheapest upgrades to any system with a subwoofer. Big improvement with very low cost. These really help remove unwanted sub bloat, room noise, and improves sub bass focus. Highly recommended (by me and Stereophile magazine!).

Pros: Easy improvement. Low cost. Removes unwanted bloated lower Octaves.

Cons: None.

Jeffrey from Alexandria, LA on 4/3/2017

Crutchfield Customer Review (What's this?)

Amazing product. Cleaned up my bass response, much more refined and accurate bass. It also eliminated the "wall shaking" that was driving the Misses crazy. Highly recommend if you have a quality sub!

Pros: Accurate bass response. Nice looking under sub. Best for hard (non-carpet) floors

Cons: None

Does the trick

Jeff from Pittsburgh, PA on 4/2/2017

Crutchfield Customer Review (What's this?)

I use this with a JL Audio e110 sub which fits on it just fine. It was bought primarily to get the sub off of a relatively thick carpet as it tended to sink into the carpet somewhat. The SubDude does provide a firm and stable platform for the sub and greatly reduces rattle from windows and objects in the room when the volume is cranked up. I can't say if it really provides better definition to the lower end of music as the sub sounded great to begin with but it does do what I purchased it for - very satisfied.

Pros: reduces room-rattle if you like your movies and music loud

Cons: some may think it's a bit expensive for a velour-covered board over a chunk of dense foam but it appears to be very well made

Crutchfield Customer Review (What's this?)

It's a very sturdy and rigid acoustic pad and I noticed a huge difference in my room acoustics right away. There was much less rumbling in my floor and windows, so that should help me hear the low frequencies more clearly in my music production.

Pros: Durable Absorbs low end rumbling

Cons:

Big help for cleaner bass

Cleans up the Bass

James from Bothell, WA on 12/19/2016

Crutchfield Customer Review (What's this?)

Purchased this item on a whim with a Crutchfield giftcard. Figured it wouldn't hurt, and might possibly clean up some unwanted resonance issues I have periodically when I have the volume up high. The Subdude fit perfectly under my Martin Logan Dynamo 1000 sub, and is made from decent materials (nice enough to not be an eyesore). I think it accomplishes it's mission of 'cleaning up' the bass from your sub, and I do think it tightened up the bass a bit (particularly the real low-end frequencies). Your results may vary of course. I think its a lot of money for what you get, but it works as promised (to varying degrees). Not a bad product at all.

Pros: Tightens up low end Looks do not detract from your room Fits nicely under my sub

Cons: Slightly expensive for what you get

Seems to do the trick

Scott from Santa Monica, CA on 9/19/2016

Crutchfield Customer Review (What's this?)

Ordered two of these for the subs in my living room. I wanted the impact that my subs put out without rattling the entire building. I'm in a townhouse, so I'm always looking for ways to keep the peace with my neighbors. These certainly seem to have helped, so I ordered two more for upstairs. I still have the punch and the power, but decoupling the source from the structure sure seems to have dropped the waves from rumbling the building. Totally worth it.

Pros: Inexpensive method to keep the peace and still enjoy powerful sound.

Cons: None to speak of.

Great isolation platform!

Great for protecting your sub from robot vacuums

Buford from CA on 7/21/2016

Crutchfield Customer Review (What's this?)

My main reason for buying it is to protect my sub's finish from scuffs caused by my Roomba. It served this purpose well. Any audible benefits are gravy.

Pros: Protects sub from robot vacuums, is easy to use, looks fine

Cons: It would look better if the foam bottom had a cover. I'm afraid my Roomba's brushes might wear away some of the foam over time, so I had to attach plastic buffers around the edges. Also, it's a little pricey for what you get.

2 questions already asked

Hey Brian, I currently have the SubDude-II which measures 15" square. It works really well with my Audioengine S8 Subwoofer. However, I listen to mostly classical and jazz and rarely drive the sub hard. Your Def Tech Supercube measures 14.25 square. So, it should fit fine although a little bit tight. However, the purpose of the SubDude, at least in my mind, is to elevate the sub off the carpet and provide a uniform surface density for the subwoofer to play off of so as to clarify and tighten the bass content of the music . Obviously, the SubDude HT would be a lot larger but I don't think it would be significantly better at achieving the purposes I mentioned. So, I would start with the smaller SubDude-II and see how it sounds with your setup. If not, you always have the option of returning it to Crutchfield for a refund or exchange for the larger one. One last thought is to perhaps experiment with where you have your sub placed. Moving it one way or the other around your listening area can have great effect on eliminating resonance. Good luck! [ Robert  Jun 25, 2017 ]
The Sub Dude-II should work fine. [ Michael  Jun 25, 2017 ]
Hi Brian, I have a very similar size sub and I purchased the Auralex SubDude-II and it fits on this perfectly. The Pad is slightly over 15 x 15 so it will fit your supercube. I can say that this pad did a great job stopping the issues I had prior with my sub on the floor then on a stand I built for it, the pad seems to work similar to that of what dyno-mat would do in a car and takes out ratle and other similar issues. The product code for the Pad is 927SBDDE2. Thank you [ Jason  Jun 25, 2017 ]
From what you describe about the shaking of walls and furniture, I'm a bit reluctant to say that the SubDudes will alleviate your problems. They work well for me but I don't play my music at ear-bleeding levels. What the will do, however, is allow your RELs to play as evenly and precisely as they were engineered. They elevate the subs off the floor to allow the bass sounds to radiate out rather than to get pushed down and stuck in the carpet or floor. So, given Crutchfield's wonderful return policy, give them a try and see what you think. Best of luck! [ Robert  Apr 21, 2017 ]
Yes you can, and it will tighten up the bass too. You can also try to pull the sub(s) away from the wall or corner, [ Michael  Apr 21, 2017 ]
Hi Paul...I have a REL t7i on Auralex SubDude-II which is on carpet. It's in a second floor apt. I believe it helps with the vibrations going to the first floor. I don't have any issues with wall/furniture shaking. I can definitely feel the low end in my home theater set-up when playing blu-rays but that's the way you want it to be...but not rattle the furniture. Your 2 t9i subs have more power than mine but I do think the isolation platforms will improve the shaking you're experiencing! [ LYNN  Apr 21, 2017 ]
I have a Polk 12" 150 watt sitting on mine in a carpeted room on the second floor of my home. It does a great job of dampening vibrations while providing excellent, driving lows. It's part of a 7.1 surround system connected to an Onkyo TX-NR 757 receiver. I've been quite pleased with the SubDude II. I say go for it. You never know until you try. Good luck! [ Robert  Apr 21, 2017 ]
I use this on my hardwood floor and it definitely helps send the sound out the speaker and not through the floors. My windows rattled before and now they don't, I would definitely recommend trying them. My experience has been good with using this under my sub! [ SEAN R  Apr 21, 2017 ]
