Calling the Neo Pro's pro audio is being very generous. Sindown (typo, but I kinda like it and am going to keep it) calls them "pro audio" so everyone else followed suit, but really they are bastardized drivers. He used really light soft parts with a stiff suspension to give them that "pro audio" look and Fs. But pro audio drivers notoriously suck in the midbass without a ported enclosure because, well, that's the trade-off to gain efficiency (Hoffmans Law being what it is). Since this feature doesn't sell speakers very well to the car audio market, he weakened the motor to raise the Q to bring some midbass back to the performance. The trade-off here is that efficiency drops back down pretty much to that of a standard driver because of the weak motor. All said and done what the Neo Pro's basically amount to are a standard driver with really shitty T/S parameters (and hence, performance) and no real usefulness, but good sales because they are cashing in on the "pro audio" craze. Moral of the story.....I wouldn't try to fit them into your plans.
