I second Musicnoise. Unless you have a problem with your setup then you are experiencing the prototypical midrange scoop - the VR4, like many audiophile speakers, is crossed over at 3.5 KHz - this is similar to most B&W's (for example). The large midrange will start beaming at around 1 KHz - so you tend to get a "scoop" or hole in the off axis response from 1 to 3.5 Khz...this is detrimental to voice intelligibility. This is well known in physics of speaker design but manufacturers prefer to build a speaker with boosted bass, recessed mids and boosted highs - it is cheaper to make and it sells....boom boom tizz sounds really good with music and will sell over a flat response in a shop floor A/B comparison (with untrained listeners)
Figure 1 is your problem and you need a speaker like Figure 2.
"Midrange beaming can be reduced by lowering the crossover frequency. The high-frequency drivers lower range will then provide wider dispersion and the bass/midrange drivers output can be rolled off before its dispersion narrows."
