Raising Speakers

I would like to recommend a slightly different method for you. If you raise just the front of the speaker very slightly, so as to create a small backward tilt, the drivers will be angled to aim at your ears with very little elevation. Usually, a slightly longer set of adjustable spikes on the front will handle this. You see, a small angle at the speaker creates a much larger height change at the listening chair. Also, since you only have to raise the front a little, you may retain the floor boundary reinforcement for your bass response, which you would probably lose when placing your speakers on stands.

A while back there was a similar discussion here. I think the consensus was not to use granit but marble (rough unpolished side up). It was said that the granit 'rings'. You might want to search for it in the forums.

Agree with TWL: A very "slight" adjustment to the angle will raise/lower the image quite a bit. I even do this with stand mount speakers (adjust the stand spikes to raise the front a tad, which gives a more spacious sound in my setup).

Okay don't laugh.
I own a pair of Rev 3s myself. I love "em. But, I'm 6'4" and sit in a rather large rocking chair to listen. Here's what I've done. Four hockey pucks on the floor supporting a concrete paving block 12" square and about 2" thick. Not only Have I raised the Hales up, but the bass got tighter as well. And of course my investment in all that is small.
Good Luck

As usual, Twl and Dekay are right. However, I am not familiar with the Hales speakers (no web site either I guess) and there may be one caveat. If the speakers are designed with the bass slightly forward of the midrange which is slightly forward of the tweeter, they are already adjusted so the signals arrive in phase. By "slightly forward", I mean that the bass is physically closer to the listener than the midrange which is, in turn, physically closer than the tweeter). Tilting them may reduce the predesigned phase correction and may offset the sonic advantages of aiming them at your ears. If the front of the speakers are flat with the speakers equidistant to the listener, you may pick up two advantages by tilting so it is an additive benefit.

Simple enough to find out. Use some dimes, quarters and double stacked quarters under your front cones to see if it helps -- you may also "unscrew" the front cones for some more height (leave enough thread for a solid connection though). If that sounds good, play around with different cone sizes for a more solid connection. Don't forget that pucks can also be used to raise the speakers. They can sound quite good on carpet and will also offer more height (carpet + pad thickness plus puck thickness) -- probably 3/4" to one inch for the standard 1/2" thick puck. Good luck!
