Question: Can these stands be used on hardwood floors or do they have spikes on the bottom?
Document: This is a great pair of speaker stands. High quality. Solid tempered glass and aluminum supports with a hidden steel bolt connecting the top and bottom. Easy to assemble. It is definitely the best speaker stand that I have found.
As some have mentioned, it would be great if they would have run the wire through the base plate, but it isn't really that noticeable running through the tube.There are also four spikes for each stand to prevent the stand from bouncing around. They worked perfectly for my carpet (a low plush).Overall, I'm happy with this purchase.
The glass plates set this stand apart from those that use steel plates. This is a very classy stand although I used only one for my center Martin Logan 8. In the end I had to re-engineer two into one, using the two small tubes stand side by side.
If you buy them;you will be very happy with these stands. The company seems to be a good company, they shipped them next day and they arrived in seven days tops. Great product and seller.
I couldn't be happier with the price or the look!Of course, if I wanted a pair of stands these would be the ones, hands down. As others have said, these are beautiful!old arkiedan
I have a very long center channel. Rather than buy one heavy duty center channel stand, I opted to get this stand pair which is just the right height, 18&#34;. The stands come in one box and appears to be very well packaged to avoid breaking the tempered glass plates.
I purchased these speaker stands for my def tech 350s; they have a great look and feel.These stands are made of glass and metal: I wish I could've found the 25"-30" style, that would have been perfect. Therefore, since I couldn't find them at those heights, these served their purpose. Assembly is straight forward and should only take about 10 minutes or less to put together and if you need them instructions are provided.
I bought these speaker stands after moving into a house where I wasn't able to install in-wall speakers like in my previous house. The basement had furring strips, and the stud depth was too narrow. I bought a pair of Polk TSi100 speakers, and needed something to place them on. I considered some screw-in wall mounts, but that would have required pulling out the floor molding to run wire. Too much trouble.
building directions not the best but not much to put together so not hard to figure out. quality seems good and durable for the money
While the glass bases have a nice heft to them, I was somewhat disappointed by how thin the aluminum posts are. That said, there is a center rod for each posts so that in totality, there should be enough strength. Definitely do not exceed the recommended weight though.
Answer: The spikes are removable. Nice stands!
