Building stands for a pair of Monitor Audio r352 speakers

Hello,

I recently picked up a pair of Monitor Audio r352 speakers of eBay, but they didn't come with any stands. I like the look of the stands that came with these back in the day (see the attached photo), but I can't find any information about them online. I reached out to a couple of eBay sellers who were selling the speakers with stands, but their either didn't reply, or couldn't help. I even reached out to Monitor Audio, who after a while got back to me to say they also had no information in the archive, nor did they have a pair in storage.

It's a long shot I know, but I don't suppose anyone on here has a pair of the stands and could supply me with the relevant measurements...?

If not, can anyone recommend some rules of thumb, around the size and thickness of both the base plate and column? The base of the speaker cabinets have captive nuts, so I guess the top plate size if pretty much self explanatory. The only other thing I really need is some for some guidance over the angle the speaker sits at.

Any construction tips for stands? Is it simply a case of screwing the column to both plates and calling it done? Or is there a better way of joining everything to help dissipate, or mitigate, vibrations coming up from the floor?

Any help would be much appreciated.
 
Main thing is to get the tweeter at ear level and the rest can be scaled from the pic if you have the speakers which would be close enough. 25mm for the base is ample and 20mm for the top but use what works. The column can be whatever is aesthetically pleasing and 75mm x 100mm would be a good starting point. If the speaker has captive nuts then they can be securely attached but if not a strip can be added to the back of the top to stop the speaker sliding as well as some BluTac.

The angle I assume would be so the speaker would be pseudo time aligned. This is so the acoustic centres of the drivers are in vertical alignment. You can get close enough with the distance of the centre of the faceplate for the voice coil gap and the distance between the drivers (Tan-¹ (Hd/Cd). I did a 2 way 6" Scan Speak and it was 8°.

Use fasteners to connect the column so the stand can be modded for other speakers if desired. For the base I only use 3 point loading with gives better stability on variable floors. I don't use spikes as have hard floors and use half sphere feet.

Thanks for your reply. There's an eBay listing that shows the stands off really well. Unfortunately they haven't replied to my message asking if they'd be so kind as to measure them for me.

Other than the angle, I should be able to get close enough to all the other measurements using the photos on that listing, along with my actual speakers. I can always try and use the equation you mention to see if I can get something that sounds sensible.
 
I've kept asking on eBay, and someone has finally been kind enough to answer with measurements. I still need to turn these into a drawing, but wayhay!

Base plate: 2cm thick, 25cm wide, 32cm deep
Upright pillar: 21.5cm from back to front, 5cm across at the front, front facing height 31.5 cm, rear facing height 29.5cm
Top plate: 22cm from back to front, 14cm across and approximately 0.5cm height
