Increasing height of stand-mount -- what to expect


I'd like to increase the height of my stand mount loudspeakers, perhaps by putting something on the floor and then setting the spiked stands atop that piece of stone or whatever. (They are dedicated stands, so I'd not want to put something between them and the speakers.) What I'm after mostly is getting the tweeter more on a level with my ears, but I'm wondering if increasing the height of the speakers would have other effects, mucking with the bass, for example.
Yes, I know I could just try it out and listen to find out what happens, but I'm wondering if there's some rule of thumb, something to anticipate.
Thanks.

Usually speaker manuf design speakers such that the woofer distance from the floor is a specific amount. This relates to the woofer coupling to the floor for the intended bass response. Moving the speaker up chnages this distance & chnages the bass response. You might want to contact your speaker manuf to see if they have such a desired woofer-to-floor distance or not.
Yeah, sonics are not that good when your ear is above the tweeter since for most speakers the vertical dispersion is terrible (you can see this in almost every speaker tested by Stereophile). So, your idea to get your ears below the tweeter is a good one.
Usually the best sound is when your ear is 1" below the midrange driver in a 3-way & in between the drivers in a 2-way. So, it might actually be better for you to lower your seat.
