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!
