The short answer is to move your chair closer to the speakers. Measure from tweeter to tweeter, multiply it by 0.83, and use that number to determine the optimal distance from the right tweeter to your right ear. (Jim Smith’s method, it works)
The longer answer involves optimal ear height (often a foot or so higher than the tweeters on two-ways, easy to check), optimal speaker distance from the rear and side walls (different depending on speaker type and room layout, and much harder to get right), and not using that questionable super-toe-in method that’s become popular for reasons that escape me.
It’s also worth bearing in mind that if the room has no opening to release pressure the long bass frequencies will create a mess of reflected sound and the midrange will suffer, which is where the holographic magic happens.
