[QUOTE="nineballsafety8, post: 3759247, member: 583462"] thats a pretty bold statement there george... i would agree only if they were both sealed in .707 Q box... if you go ported... there are WAY to many factors that could go awry. in a perfect world they should sound very similar... but mathematically two HDC315's in the same box will technically sound different. its IMPOSSIBLE to have exact specs across the board... but then again car audio is anything but a perfect world. in my experience (contrary to popular belief) the more cone area you have for a given amount of motor force to more accurate you will be for a given amount of power applied (within reason) so if you have a single 15 and a single 12, both with the same motor structure... the 15 only has to move roughly 65% as much as the twelve to pressurize the same amount of air. so basically as long as you have an adequate amount of power to control the cone of your sub... more cone area in a well built box will sound better than less cone area with a more efficient box to compensate for the lost output from lack of cone area. just my thoughts though [/QUOTE]
