Do Sub Stands make a difference?

I have a pair of JL 113. I am considering Sound anchor stands. Do you think they will make a difference. They are certainly good looking.
 
Big B.......I have my JL Audio Fathom f113 on a Sound Anchor stand. It provides a rock solid and heavy base for the Fathom and I noticed an improvement in the tonality and fullness of the subwoofer once it was elevated. It makes a fine stand and gets the subwoofer out of the way of the vacuum cleaner, too. Don't stub your toe on the Sound Anchor stand. Ask me how I know...:)

Ok I'll bite. How do you know?

I found just getting it up off the floor was an improvement and I am sure a more solid bass than I am using now would be better. I originally had it on a stone slab on tennis balls, with sorbothane under the feet and that was decent. When I ended up with an extra VTI shelf, I utilized that. Yhis is an older pic and sub is in a different spot now.

I'm sure there is some advantage to the isolation a good stand will provide, but with the subs a major benefit is getting the driver(s) further away from the floor. Just as with the walls and ceiling, there is interaction between the driver and the floor - being very close to any of these will augment the bass but at the expense of some boominess and or uneven bass at the listening positions.

I don't have any experience with stands. But I did try some Nordost pulsar points under my sub when it was located on a wood floor. With the standard rubber feet or spikes w/floor protectors, the sub vibrated. With the pulsar points the vibration disappeared.

I also have a pair of F113s on custom SA stands and highly recommend them. On timber floors, spiked on QX7 isolators works well. As others have said, it's all about getting that woofer distance away from the floor.

Try to buy directly from them if you can.
 
I've heard great improvements in sub texture and tonality when raising them off the floor. If it is front firing then getting it a foot or so high works. If it is down firing then just turning it over to fire up works (but I would suggest putting a board on those upturned feet with something heavy on it (mimic's the floor and the intended opening).

Note, you may have to turn it up a wee bit louder when doing this.

Would something like this work just as well for a whole lot less?

I did this with my F113 pair, the foam isn't stiff enough to resist the crushing weight of the F113. It was a nice try.

The Sound Anchors look good, though it's best just to say it lifts them up and keeps them off the floor (for a variety of reason). There would have to be some good testing done w/ and without the stands. Still Double-D has sound judgement, buy them like he did- you can only be sure after you did. :D
 
I have a single JL F113 that is sitting on a hardwood floor and it works well. Haven't tried experimenting with lifting if off the floor. JL is in the business of making and selling subwoofers, maybe a leader in their field especially with car audio. My question is why would a manufacturer design their subwoofer to sit on the floor if raising it a bit (e.g. by designing a taller enclosure) would improve its performance as others have stated. Of course, everyone's particular listening room will have different responses to these adjustments. Not supporting or denying that Sound Anchors makes a difference. Just wondering why JL didn't think of it first. Any thoughts?
 
Lem321....I would say cost and logistics. Those Sound Anchor stands are very heavy and nearly weigh as much as the subs themselves.
 
The sub should be closer to the floor. The further off the floor it gets, the more likely you will get a "floor bounce"; SBIR cancellation from floor. Of course, it all depends on how far the sub is from seated position. But as a general rule, bass drivers should be closer to the floor.
