[QUOTE="squeak9798, post: 2644438, member: 555320"] The "dispersion" isn't the primary reason for not having door mounted mids. The "dispersion" will affect the aiming of the speaker. And yes, some domes (but not necessarily all) have better dispersion characteristics than cones which allows them to require less "aiming" of the speaker itself. But the reason for kickpanels as opposed to door-mounted mids is due to pathlength differences. The midrange frequencies are sensitive to [I]both[/I] speaker aiming (intensity differences) [I]and[/I] time arrival (pathlength) differences. Additional note; Midbass frequencies are rather insensitive to aiming but [I]are[/I] sensitive to pathlength [time arrival] differences and "tweeter" frequencies are sensitive to intensity differences but rather insensitive to time arrival differences. The only way to "fix" time arrival differences are to either equalize the pathlengths or use time alignment....and time alignment will typically narrow the stage as compared to optimized pathlengths. Also, typically kicks will allow you to more optimally aim the speakers as opposed to doors where some oddly-angled drivers sticking out of the door may disrupt comfort while sitting in the vehicle or may look hideous aesthetically. The main downfall of qlogics is that the aiming may not be optimal for your particular speakers. However, if you the imaging from the aim is good with the speakers you are using....solidifying them shouldn't pose any issues at all and should be just as good as "custom built" kicks of the same aiming/size/shape. As much as it takes to eliminate pod resonances and sturdying up the mounting surface. [/QUOTE]
