Spread the Daf!
yep but one caveat ...... there ARE speakers designed to not be aimed at your head and they can be a bit too bright if you aim them there.Tweeters are very directional. As the frequency goes up, the dispersion decreases. By toeing them in to where they're pointed at you, you finally heard a flatter response and more high end - it's that simple. If you toe in any speaker so that the tweeter is more or less pointed at you, you'll get more accurate sound. Duh !
Perhaps that's more in audiophile stuff but the lobes of dispersion from that tweeter are sometimes taken into account during a speakers design and they'll voice it to be heard off-axis.
So it's not ALWAYS the case with every speaker there is that on-axis is the most accurate spot.
