View Full Version : Get your sub up off the floor?

Curious as to what is thought about raising a sub off the floor. Subs are large and bass is omni-directional, but I have had speakers in the past, floorstanders, where if the speakers were standing on the carpet, the bass was mushy and just plain lousy. By putting in the spikes, and placing the speakers on a 1" thick pc of granite, decoupling them from the floor, the bass improved a great deal.

So has anyone experimented by putting the sub on say an Amp Stand or higher?

I ended up with an extra 7" VTI unit that I am thinking of experimenting with and lift the sub up. There has to be some difference whether good or bad. I'm hoping for better because the same theory of decoupling a floorstander to improve bass should also apply to a sub.

What say you?

Actually, I lift my sub about 2", thinking somehow that doing so will help the sound. One one hand, his is probably irrational: the sub fired out, not down; on the other, it seems reasonable, since it has been placed inside an schrank, where the vibrations already give the doors a good, occasional rattling. So far I like the sound. I haven't done an A-B comparison: most times the volume is cranked low enough to be scarcely discernible. But, I am not you, so who knows? Why not give it a shot?

Mine fires down. I do have spikes left over from another build. Do you think it would make a difference?

I do not know what a "schrank" is. :idea:

One of these days I'm going to get the nerve up to drill the necessary holes into my sub's cabinet and install the spikes I purchased from Parts Express 2 or 3 years ago.

Well, other than what happens to certain things in German schwimming pools, a schrank is another term for an armoir, Rich...

OIC. I don't think my sub will fit in there though. :nonod:

I bought a 12X12 concrete paver from Lowes, wrapped it top and bottom in padded black vinyl and sat my forward firing Sunfire sub on top of it. Without the paver, the Sunfire resonates the hardwood floor but with it, the bass is nice and tight and compliments my full rangers.

My dual Dayton subs have spikes first placed on berber carpet. But when I went to home depot and purchased 2" x 16" gray masonite pieces and placed them under each enclosure (towers and subs) still all spiked, I noticed a more defined, clear, and sharper sound with zero vibrations. You cannot dampen them any better than this I don't think. The sound greatly improved and tightened up all freq ranges. Best .75 cents a piece i've spent to make great sound.

I originally had it on a 18 x 18 x 1 pc of quarry stone sitting on bricks. I took that all out of the mix when I redid my system to the VTI racks.

I think what I will do, is put the block on top of the 7" VTI shelf decoupled with several 1/2 in thick pcs of Sorbothane...then the sub.

That is the answer I was looking for and what I experienced with floor staning Mirage Speakers I did the same thing to.

Of course he hasn't, nothing has changed since he started coming here several years ago, interestingly enough he still hasn't posted any pictures of any of his equipment either, which his excuse years ago was a broken camera, but I think or at least I would hope most people by now have caught onto the fact that he tries to talk the talk, but has never walked the walk and thus one of the reasons I left 2 years ago when I did from this place. I am shocked to see that he is still around making ridiculous statements without any support.

I put casters on my forward-firing sub. My intent was to limit how much it vibrates the floor and thus the turntable. I also put open-cell foam in the port...but hey...that's just me.

Dude, Pix had absolutely nothing to do with your leaving this place 2 years ago.
Now, I'm willing to leave the past in the past, but don't go slinging mud at members in your sunday whites, mmmkay.

Mine fires down too, and I have a high profile rug. I put a piece of wood (from an old shelf ) under mine. To me (after turning the volume down) it was more clear, dynamic, not as muffled. Spikes my do the same for you.

I think there is a big difference and a lot more issues raised (pun intended) by going from 1 or 2 inches off the floor to stands. IMO Subwoofers have been around long enough that either a manufacturer of subs or of stands would have developed the concept if there was any benefit to it.

Well since you obviously know me better than I know myself, please enlighten me why I chose to do what I did? The problem is that you (along with a few others) think that you "own this place" and therefore gang up on anyone that you feel indifferent towards in order to satisfy your pathetic life that you live in the real world.

Well wether or not Manufactures would have figured out if they sound better raised or not, they chose not to include it in the design for many reasons I'm sure. But......

It works and did for me exactly what I was hoping for. I used the 7"tall VTI shelf, placed 5 chunks of Sorbothane on the wood shelf and then an 18x18x1 slab of quarry stone on top then the sub.

I did this while it was on and Kansas Komp was spinning. Although that comp is not a stellar recording, bass was less muddy. I went to get a shower before any more listening and when I got out, I could hear that Mrs Hyfi had put on some Les Dudek at high volume. Sounded much better from upstairs even.

I was able to turn the sub volume up which allowed me to better blend with my mains while the floor, walls, pictures, and windows were no longer rattling and vibrating. The bass was clear, detailed, deep in your chest and better than I ever had it setup in my room.

Then the real bass test cd went on. Thanks to a bud here that turned me on to this disk which anyone should own if they want to see what kind of bass their system can produce.

MARCUS MILLER M2

I cranked this baby up to high levels and the bass was as tight as it could be when before with same disk it was muffled at times and the room vibrating got in the way of the sound.

I think maybe everyone may not get the same results as I did but maybe worth experimenting with. It worked for me.

BTW my sub is a Mirage OM-12 which I don't think they sell anymore.

Hey PS,

Good to see you again.

If you look around, you'll find that Pix is not the most popular guy around here. I don't think he cares to be. But you made it your puppose in life to run him out of town. That made you out as the bad guy. Let's let it all go and move on.

How do you feel about subs on the floor? I have heard about something called a "grandma" that people are using under their subs. I don't know what those are, but they could have picked a better name.

I don't have any experience with my sub Hyfi. It is used in my HT system, basically for movies and I have it set for really low bass, since my mains can handle most.

What I can tell you, is I have alot of experience with my rig for my bass. There was a time when I gigged quite often. Using a 15" with a 2 - 10" on top, I sometimes had to elevate the stack on milk crates or wood in order to get the sound to travel further down the club.

I always hated doing that, it sucked all the bass out of the floor. Took away all that "feel" from under my feet. It was great for tightening up the sound though. Higher notes really shredded, and lower notes took on improved clarity but I still wouldn't trade that rattle for anything.

Agreed.

There is no fear of crapping a thread here at AR, because the mods allow regular members freedom to post whatever. For the most part, this is great. I however don't feel the same.

When things go as directly off topic as they have here, I think the EDIT button needs to come out. When there is no value to the posts, and they are made out of spite or anger, they are useless.

At least when some people argue here, there is great info still to be had in their posts.

Not trying to play a heavy, but there has to be some limits.

I see it as almost the same as room tuning to get rid of the same effects that lifting up the sub will do.

Hmmmm. Yeah, cause I picked up on his B.S. from day one and called him out on it, which apparently was my mistake, but I refuse to let someone float on and on about stuff that they really don't know anything about. This place is to help people with our accurate experience of things and to help steer people in the right direction if they need that type of help.

Thank you for the "welcome back", it's nice to know that someone enjoys having me around.

As far as the subs go, I actually crafted my own set of legs for mine using cushions that they sell for people who have furniture on hardwood floors, it's a small circular foam bad that serves the purpose well as you can get it in a half-inch size and there is an adhesive on the back, so if you take two of them and stick them together, you can get 1" of lift and place them on the four corners of the subs. Because they are designed to hold the weight of furniture legs, they are firm and fully capable of any subs weight.

Yeah, I'm good. Just like anyone else in the world, I personally don't care for being accused falsely of something and the fact that certain people around here are saying that I am alternative users and other users from the past, is insulting and furthermore, the Mods here know it and won't confirm the truth of the matter.

There is a level of arrogance from certain regulars here who seem to think that anyone who doesn't see eye-to-eye with them (and there are lots of them) must all be the same person because how could more than one person in the world disagree with them or the antics of this site....? It's just pathetic really.

I am not going to back down, but will mostly be spending time on this site like before answer questions that I can, making observations about various posts, and healthily contributing however I can. It's a fun place, despite some dysfunction.
