This is a difficult concept to truly grab and accept but because of my experience in audio in other arenas I have to agree. But //content.invisioncic.com/y282845/emoticons/graduate.gif.d982460be9f153bb54e5d4cb744f6ae8.gif
Finding quality 8" drivers that can handle the power and abuse that we tend to subject these drivers to in car audio, has been nearly non existent. This really has changed recently. TC sounds epic 8" and American Bass (examples) have impressed many with there sound quality and thunder but still not quite what we like. Look at Sundown X8 and Digital Designs SW2508 (examples) and wow, now we are actually seeing progress. These 2 examples can easily prove what you are saying.
Thanks for the article bro man, it was a good read.
