What about Dannys U-baffel with the 8" on the side. No body whrite about that project, is it a bad solution or to new project.
It is not a bad solution at all, just different. The speaker stands you are talking about ended up working like a ported box rather than an open baffle.
If you are pairing them with a ported or sealed monitor and/or need to place them close to the front wall they would be a great choice.
However, if you are wanting the open baffle sound than those stands would not be what you want while the designs discussed in this thread would be.
It's just a matter of different designs for different applications.
