Speaker listening position higher than tweeter


I purchased Spendor Speakers 1/2E with speaker stands. The stands are pretty low. Even with the stands, the speakers tweeter is below my position on my bed in the bedroom. I believe these stands were recommended for these speakers. I am not the original owner. In any event, is getting a higher stand my only good option or can I put something under the stand to elevate them further?

Michael,

Here's the link to the stands I think work well, and they are not bad for $100 shipped. I have them and have been very pleased:

My splendor 1/2e speakers are big but not floorsstanding and looking to raise 20 inch off ground. The current stands are only 12 inch high. I thought of finding a way to tilt but think might be unstable
Is it a dumb idea to leave each speaker on it's speaker stand and put the stand on a low height coffee table to get tweeter near ear height?
