Bingo!

As a coherency freak, I find that flaw immediately noticeable. A friend and I were comparing his modified Advents to JBL L-110s - the more neutral sounding cousin to the more famous L-100 Century. While it was quite neutral in character and had a more extended top end than the Advent, it ran the 5" midrange up to 5 kHz. The problem is the driver beamed horribly at the crossover point - where the wide dispersion tweeter took over.

The result was an image that resembled a fun house mirror: frequency-wise it had a wide stage at the top and bottom but noticeably pinched at a critical mid point. Very unnatural sounding.
