[QUOTE="Doxquzme, post: 8891818, member: 689267"] I think that is a bit of an oversimplification. This truck door has nearly 1.25 cu ft of airspace so even if the OP was using this for bass (below 80hz)it would be sufficient if any of the drivers were optimized for that output, which most all 6x9's are not. All the models listed here have decently low modeled EBP spec of 45 to 52 and their Qts are high at .6-.9 which points to them being geared to IB (door or package/parcel tray), and don't do well in enclosures, comparatively. He's also combining these with the 6.5 coaxial versions from the same models. ALL the models he is considering are designed to reproduce midrange to around 5k so he will be fine. Using a 6x9 is a great option as it picks up the 70-100hz bandwidth much better than a 6.5" as it is closer to an 8" driver. Additionally, the sets he is looking at with the metal domes, should he go that route are crossed at under 3k. Having built and repaired a multitude of pro guitar and PA systems, 8" midrange drivers are pretty common. It's more about the driver itself as most any well designed midranges between 5 and 8 inches can do quite well up to around 8k. I would agree that inexpensive metal domes on passive crossovers can seem harsh compared to inexpensive silk domes but metal domes as a whole, tuned correctly, can be just as smooth and are often more articulate than their silk counterparts. The ZCH line the Pioneer offers have an alloy tweeter (to 96k) that provides a flat, -3db and -6db setting to compensate for their efficiency and percieved attenuation differences at 12k and 20k which can make many metal domes "ring" which is interpreted as "harsh" as it messes a bit with upper stage harmonics and creates ear fatigue. In a dash, facing upwards, this can be an issue for some applications (passive versus active). Very good metal domes, tuned correctly, can exceed the accuracy and articulation of their silk counterparts. All of this metal dome talk is still quite subjective.
