I needed your input in possibly designing stands for my JBL 4345 Clones.
The issue: The 4545 monitors are currently situated in our Sunroom. The Sunroom was actually an addition to our house and was constructed on top of our deck. Hence, the Sunroom is suspended in mid-air. Our deck was torn down and the new floor for the Sunroom was built using 2x12 studs + 3/4" ply + 3/4" hardwood floors. The floor itself is suspended on several 6x6 posts.
Although the floor of the Sunroom feels beyond sturdy when walking on it - the JBL 4345 still manage to send vibrations through the floor. I personally feel this effect takes away from the overall sound - as of the 18" diver is losing its sound. It might just be my imagination, but I feel the speakers sounded "better" when I had them in my basement (i.e., on concrete foundation).
I wanted to know if it would be a worthwhile venture for me to build something similar to the "Sub Dude HD" subwoofer isolation platforms. Or even wood stands like THESE with spikes to "decouple" the speakers.
Any thoughts would be much appreciated.
