Agreed, (3) points are better than (4). Not to trumpet the brand but Live Vibe espouses (3) points of contact. (3) points will always equalize whereas (4) points are prone to wobble.
I've not tried placing weights on the top of the monitors but I love the suggestion. Easy enough to try it out. Thanks.
I was worried about rear mounted woofers until I heard a couple models. Both the Kii Threes and the Dutch & Dutch 8c's have very clean bass and great imaging (a tell tale test for any box suffering from vibration issues).
To be clear, I'm not experiencing any imaging or excessive vibration issues. This project is more aesthetic than anything else. I just don't want to introduce something that would be a step backwards. I would assume most objects with a decent amount of weight/mass well anchored to the floor would suffice.
I had originally thought 1/2" or 1" steel plate would be a good material but apparently any surface that you might rightly call "plate", even a very heavy one, is prone to ringing. Take note those of you with large DACs or Amplifiers. Easy enough to test, just rap the top/side of your box with your knuckles. Thus something monolithic like a good size chunk of stone would appear to be a better option. Not perfect but better than most speaker stands I've come across.
Thanks for chiming in folks, I really appreciate the input. Always learning something new from you all.
