Question: How much weight will each stand hold?
Document: The tube is hollow with cut-outs on both ends to run cable through, but I find it odd that you can't slip wires through the bottom of the base instead. Not a significant issue, but it would make cable management a bit more attractive.Stability is pretty decent in my experience, but keep in mind that the base only has three legs and will tip if knocked with enough force (a true statement for virtually any bookshelf stand without massive weight in the base).
These look and work fantastically well. Holds a lot of weight. Easily over 20 pounds each. The only thing wrong I found was that its height. These would use some height.
This set comes with two stands, so when you think about it you can get these for a great deal depending on when you buy.One thing to note - go to walmart and buy some strong velcro strips to ensure someone doesn't accidentally knock over the speakers. The speakers would otherwise be sitting there on a platform with nothing to hold it.
I ordered three pair of these stands to hold my hsuresearch speakers (8"x8" base, 20lbs). Of the six stands, two were entirely defective: stripped bolts, broken welds; the pillars are cheap, thin-walled aluminum. the bolts and spikes flimsy. The stands are unstable (base is too small) and poorly manufactured. i have no confidence that these stands will perform over time.
I am very pleased with this product, and the service from price pro's. the order arrived in good condition, no missing parts, and after just 4 days from placing the order.Assembly was quick & easy, directions were adequate ( no brain surgeons needed) and the stands look good. I am using them to hold a pair of Infinity Reference 2000.3 speakers, these are not tiny satellite speakers, weighing about 15 lbs. and the Sanus stands do a good job.
Really not bad for what you're paying. I've placed Paradigm Series 7 Atoms on them and they fit pretty well The color and finish of the powder coat is really unobtrusive and matches the color of the black ash speakers really well. . I'd definitely recommend  using an adhesive like stick tack (that blue stuff teachers use to hang posters) or 3m adhesive clay. It will hold the speaker down and act as a vibration absorber.
The Atom monitors weigh approximately 11 pounds and are slightly over 10" deep and 6.5" wide. Although I previously stated stability as decent, I should qualify that remark with the following: only with small speakers. I would not want to put my front bookshelves (Paradigm Studio 10s) on these stands as it would make them quite top heavy. Most bookshelf speakers should fit on the larger top plate in terms of physical size, but weight could be an issue.
I was going to buy a 24" stand but I am happy that these stands are a little higher at 28" because it is level to my ears when sitting down on the couch. Overall, I am very happy with it!
I bought these for a couple of surround sound speakers. The stand itself is fairly heavy, but with my speakers on top, it just wasn't very stable. It was quite easy to knock the entire setup over. Secondly, one of the stands ended bending at the base and I had to throw it away.
Only one stand of the two I ordered was shipped. The vendor promptly shipped me the second stand with no additional charges. They are very sturdy. Wiring can be hidden inside the stands and they have carpet studs for the base that can be removed on hard floors. The description should include the dimensions of the top platform that the speaker rests on. If your speaker is small, some of the platform will show.
Answer: My NHT SuperOnes are about 15 pounds each and the stands handle that weight fine. Much more, though, and you'd better make sure of your floor, or use the spikes.
