[QUOTE="tommyk90, post: 6329669, member: 545293"] Wow what a trainwreck. I don't fully comprehend the 10 mm vs. 10 mm discussion. So you're trying to tell me that a cheap sub moving at full xmax versus a DD 95xx moving at full xmax (they are known for minimal travel) will produce similar numbers? I'd beg to differ. Sounds strange, but isn't the FORCE that the motor is producing going to create higher SPL given the same amount of xmax? It's kind of hard to explain, so hopefully somebody more technical understands what I'm trying to say. On to the dante discussion (which shouldn't have happened in the first place), all he did was test and tune his vehicle to the max. If you go back 15 years ago, people were saying how impossible 170 dB was. 10 years ago it was 175. 5 years ago it was 180 dB. His car is not some SPL anomaly, it's just a very finely tuned speaker enclosure on wheels. To use any extreme car in a discussion about efficiency in a real world situation is an effort in futility. Those cars are literally speaker enclosures. There's no "cabin" in a real world sense. Anyways, I'd be interested to see some of these super efficient speakers at least tried in today's SPL vehicles. If somebody wants to send me one I'd be more than happy to test one out. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Hell IDK.
