Some notes about assembly and fine-tuning:1.Full height back support for your Mag's is not necessary. It will do nothing good unless you think it look good with full height. I will recommend half height of your mag's. Also, don't use more than 4 screws to fasten mag panel in order to avoid bending the panel. Once the panel is bended, the characteristics of unique Mag sound will be altered. Four screws are enough to hold your Mag's steadily.
2.Tighten two bottom screws first. Don't over-tighten them. The holes through the tips of the back supporting legs should be big enough to allow screws move slightly. Doing this is to avoid
bending Mag panel, too.3.It is very important to use weatherstrip tape between Mag panel and supporting legs. I use ¾" width and ¼" thick weatherstrip tape from Home Depot. The proposes to apply weatherstrip tape are to avoid bending the panel and to add some sonic characteristic. Mag's without back support sound somewhat too soft. Simply adding absolutely rigid back support may make Mag's sound nervous. By applying weatherstrip, your Mag will sound somewhere in between too soft and too tight. This is what I prefer. On a low-resolution system, you may not be able to hear the difference, but you can be sure that you don't bend the panel. After tightening top two screws, you need to check the pressure by holding the tip of back supporting leg and side of Mag panel to see if the tape bounces back. If it does, you don't tighten the screw too much. If it doesn't, you need to lose
the screw. LET YOUR MAG'S STAND UP NATURALLY.4.I fill half of base with sand. Why half? Because I don't want my Mag's sound too lean and too tight. Does half make difference? I don't know. Maybe not.
5.I also cover the inner side of back supporting legs with wool fabric to reduce unwanted reflection. I think it may not be audible, but I am a perfectionist. So, I did it anyway.
6.I got my spikes from partsexpress.com. Those spikes allow you adjust the height in about ¾" range, so you will be able to tilt your Mag's. I use 4 spikes, therefore, I have ¾" to work with on the front and back. To my ear, it is enough to change the height of sound staging. If you need more, you may just place something under the spikes.
Most of people here own 1.6's. This plan is also good for 1.6's. I really enjoy my new stand and think it does improve the sound of my Mag's and they look nice as well. Good luck if you want to built a pair for your mag!

Just wondering.

It is all wood stand. I know I should take a picture of my stands. But I am lazy, to draw on computer is much easy for me.
What computer program did you create the image with.

> Full height back support for your Mag's is not necessary. It will do nothing good unless you think it look good with full height. I will recommend half height of your mag'sHow you determined this?
Let's take your stand as example. The frame, which you mount Mag on, is not perfect flat. It must be croaked. Actually, it is almost impossible to accomplish this. It is same for my stand. Now, let us look Mag panel. After it is on stock stand for while, Mag's frame, which basically is half inch MDF, will be "broken-in", too. It will form certain shape that we don't know. So, it is an impossible task to match both perfectly. The taller the stand is, the more imperfection may occur. This is why I think full height is not desirable. . If you want to use full height support, you need to have some kind of device to compensate that imperfection. I use Marine and Automotive Weatherstrip Tape. Also, in my opinion, half height of Mag panel for back support is enough to achieve rigidity of you Mag.
