is designed as a no-compromised Monitor. When supported
with a Subwoofer, the performance will rival speakers costing
many time more.
we proceed further, let's take a closer look at the ZA14.
Fig 1 is the manufacturer's SPL/FRQ plot. The most obvious
anomaly is the sharp peak centering at about 9kHz. This
kind of peak is cone breakup due to the use of extremely
stiff cone material, in this case, aluminum. What is less
obvious is a +3dB hump at about 2kHz. Bear in mind that
this response plot is with the ZA14 mounted on an Infinite
2 is a SPL sweep with the ZA14 mounted onto a box with a
baffle of 8.5" width. Disregard the region below 300Hz.
The measurement is inaccurate due to room interaction.
cone breakup correlates to Fig 1. However, the rise in the
mid frequencies is now greater. We can see clearly the climb
starting from 400Hz and peaking at about 1.4kHz. The difference
between these two points is +6dB. This is the classic case
of Baffle Step at work. If this effect is left uncorrected,
it will result in a response with heavy emphasis in the
mid-range, leading to speakers that some describe as "shouty".
