Specifications
† Typically, in-car response including vehicular “cabin gain”, or the gain expected
with midbass coaxials installed in the vehicle, will result in an extended midbass
and upper subbass response. This is a result of these frequencies being below the
lowest resonance in the vehicle (typically around 50-125 Hz in most vehicles). In
more practical terms, install the Mirus coaxials into your vehicle and you will see
a dramatic improvement in midbass and upper subbass output, much more so
than just simply listening to the Mirus in a large room, or worse yet, “free air” (we
don’t recommend even trying the Mirus speakers in “free air” without some form
of enclosure or infinite baffle for the coaxials).
