There's been talk here and again about having the empeg digitally compensate for the shape of the car's interior or inadequacies in the speakers, etc... Here is Alpine's shot at it: http://www.alpine1.com/html/D2_n_1_n_n.html (click the first link). Here's a quote:


The car interior is an acoustician's worst nightmare.

From the hard dashboard and windows to the plush seating - not to mention the irregular shape of the interior itself - the physical elements inside the car obstruct and disturb the sound in extremely complex ways.

High-quality sound reproduction is impossible when the various frequencies in the music reach our ears at different times. Imagine if the members of a band or orchestra played ever- so-slightly out of time with each other!
More importantly - and more devastating - is that this time lag adversely affects phase relationships, cancelling some frequencies while unnaturally emphasizing others.

Worse yet, each vehicle interior is different. Which means there is no solution that can cover every car.

Or so we thought.

Alpine engineers came up with a digital system so advanced, so sophisticated, and so powerful, that it accurately measures your car interior and automatically time-corrects the various frequencies - as the music is playing!
