Wow Karnaaj, $75 is a darn good deal on these

My 18 inchers were on sale for $84 a year ago (+ substantial shipping from Springboro, OH to Cali 'cause, as you've found, these are pretty heavy suckers) and I was sure pleased.
Fill 'em with sand (if you haven't already) and put a couple of good blobs (taller than the corner spikes) of Blu-Tak, Mortite or PlastiClay so they are rigidly 'clamped' to the stands and you have some real improvement on the cheap.
I also bought Parts Express constrained layer damping sheets and covered the (underside) bottom of each stand (top and bottom plates) to really eliminate ringing that might interfere with the tunes. You don't see the damping sheets if done on the underside.
Hard to beat the deal with these Parts Express sometimes. They buy containers of stuff from China and we all save big on the direct-made stuff they bring in. Most other places you buy from are so small that they have no economy of scale in costing/pricing.
Enjoy the tunes...
