[QUOTE="Immacomputer, post: 8289039, member: 570419"] This isn't entirely true. True that if the response is flat, you're sacrificing max spl for bandwidth but enclosure efficiency has a lot to do with output. A properly designed transmission line (one that fits the driver AND the vehicle) will be much more efficient than sealed enclosure and more efficient than a bass reflex enclosure. That means there will be acoustical gain even with a flat response curve. My tline in my old Integra was leaps and bounds louder (a good 4dB) than any of the bass reflex enclosures I had it in, louder than a ghetto 4th order BP, and louder than a DCTV box I put it in. It was also flatter and had WAY more low end extension while still being able to play very well above 60hz. And that's also ignoring the amazing transient response that was achieved vs the nasty port delay some of those boxes had (my god the DCTV was sloppy as all hell). [/QUOTE]
