Review: This thing went from my bass shaking the whole house like an earthquake to me being able to play hip hop at 6am and nobody wakes up in the house
Review: I purchased the Subdude as my last "hail Mary" before potentially being forced to replace my subwoofer with a higher-end sealed sub. I was experiencing ongoing bothersome bass issues with one of my home theatre setups. Hardwood floors with a Paradigm front firing, rear-ported sub, in the front corner of the room, resulting in boomy, uncontrolled bass. It was like this ugly wall of loose, muddy bass was consuming the whole front wall where my TV is, then reflecting to my seating position. Due to the room configuration, I do not have other options for placement of the sub. I started looking into room treatment options but there was no way I was going to install ugly wall mounted bass traps in a main floor family room, opposite a kitchen. I was wondering if the sub was transferring too much energy to the floor, which was then moving to the walls, causing additional resonance, generating additional sound waves, resulting in the terrible sound. I didn't have these issues when the sub was in my basement. I read hundreds of postings in different AV forums and countless reviews about the Subdude and how it will 'tighten up' bass, etc. I was thinking there's no way it can tighten up the bass but if it could potentially reduce vibrations, maybe there could be some value. Some 'haters' on the forums will say the subdude is useless and people's perception of the sound is strictly psychological. After reading a review from a professional publication, where they noted they always use an Aurelex Subdude when reviewing subwoofers, I decided to take a the plunge and gamble almost $90 on this product because I had nothing more to lose... it couldn't possibly make the sub sound worse. I installed the Subdude, actually upped the volume on my sub by 1 notch, then re-ran Audyssey room correction on my receiver, so the gain would be at -4. SVS recommends adjusting gain on the subwoofer so post calibration, it's set between -4 to -8, so I took their advice for my Paradigm sub. After manually adjusting speaker crossover settings in my receiver, I was ready to test. The sound quality difference was drastic. That ugly "wall" of bass I referred to earlier is completely gone. I am finally enjoying my sub in this room. The bass is now much cleaner and is not longer an annoying distraction. The bedroom above the sub also has less bass transfer via the walls but loud low frequency soundwaves will still easily penetrate through the floorboards. Although it may be cheaper to go to the hardware store, get a piece of wood, put some foam under it and built it yourself, I'm not sure you would get the same results, as this is firm acoustic foam and not something your furniture would be shipped in. Not all rooms are the equal. You'll have different furniture, flooring material and objects that affect sound reflection and absorption, so your results may be different but this Subdude solved my issue and saved me from potentially dropping $1000+ buying a new sub and I may have ended up with the exact same issues. I was hoping the Subdude would give a marginal improvement in sound. I was shocked how much difference it made in my situation. I'm now considering buying another Subdude for a different subwoofer. No regrets.

## Questions & Answers

**Q: Moving to top floor apartment with Pioneer SW-8-K. Is this overkill or even needed for such a small sub?  Better/cheaper alternatives for an 8"?**
A: I don't think of this product as a way to prevent sound from moving through the building, but as a way of preventing unwanted room modes from 'muddying" the low frequencies. I have a number of these both the full size and the smaller version you are looking at and they do a tremendous job of adding clarity to the low frequencies, but I can still hear the bass downstairs in my basement. I would highly recommend the product, but I don't think it's going to prevent your neighbors from getting upset if you watch a Marvel film at a fairly loud level. Hope this helps.

**Q: Is there really much of a difference between the Subdude and Ampdude? Minus looks of course.**
A: I'm not sure what ampdude is doing, subdude's foam seems to be proprietary. Meaning that r and d developed for this product seem to do something with the sound waves. That being said this design seems to bring a noticeable difference when placed under the sub.

**Q: Will this reduce the amount of bass that travels downstairs when my subwoofer is upstairs?**
A: They should. If you have them on a wooden floor you can feel and hear the bass throughout the house. Resting your sub on it should reduced the boominess.I had the opposite problem. I had 2 Laradigm subs on my basement, resting in thin carpet on concrete. My bass was completely gone. The bass indidnhave was bloated and boomy. I added 2 of these and all of a sudden I could hear and feel my bass again. Best money I ever spent. I would also recommend the Auralex mopad for your center channel

**Q: If my subwoofer is 18 inches deep and this platform is 15 - is 1 1/2 inches overhang on the front and back going to be an issue?**
A: Overhang won't be an issue as long as the spikes or whatever supports are used to hold the sub up off the ground will sit on the ampdude.

### ⭐⭐⭐⭐⭐ Review
*by M***S on 4 January 2026*

Every single review who said they help tremendously in apartment use were true. I don't know about those who say your neighbors won't hear anything at all, but they will help A LOT. I have a Shockwafe 9.2.4 and with those 2 10 in woofers this system pounds. Loud. It would literally make the wall shake to a point where my landlord told me if there's one more complaint I will have to move out. Since then I would never go above 1 on my bass settings. 1!! Now I finally got my Shockwafe bacl where it belongs. It can finally breathe. I still can't even come close to half of what it can handle but believe me the bass has been up to 3 all day volume 34 and no problems. I'll try going up to 4 soon, carefully of course. I haven't even talked about the actual bass itself. Those reviews are true as well. The bas does sound better. It sounds cleaner. Like it has better resolution. Best way I can explain it. It's like listening to Spotify then you get hifi headphones get a subscription to tidal and listen to a track in HiRes audio for the first time. It's still the same song you've heard a thousand times, but it's like you're hearing it for the first time. That's how these subdudes make my subs sound. I've used them for years but it's like I'm hearing them for the first time. Enjoy everyone
