[QUOTE="VWBobby, post: 7368011, member: 624844"] Sounds like we are on the same page now. Yes, you are correct in assuming that I feel a smaller sub is more accurate, therefore reproduces sound more accurately (less distortion). The exception to the rule however, is extremely low frequency productions (~20-35Hz). A larger sub definitely shines in this regard. It also doesn't have to be very accurate to reproduce a 20hz tone, compared the amount of movement at 60hz or higher. Imagine trying to precisely control 300 grams (for example) compared to 100 grams at 60hz and back to 40hz, etc. Most music is very dynamic and trying to control a heavy mass to react exactly the way you want, right when you want, is a very hard thing to do. This is where the LMS motors and other extremely linear motors shine. However, even the best motor can't control a cone that isn't stiff or light enough to control. The part about the enclosure refers to how a sensitive speaker usually performs best in a larger enclosure. A sensitive speaker is usually a better sounding one. A long time ago, I came up with a working model of a tymphany array type design....before I even knew there was a term for it (~1996). What I found was that it is much easier to control a cone when there is little room for it to go. In other words, the problem with conventional speaker designs are the lack of support for the coil and cone while still allowing the cone to move freely. This is why its better to have several smaller cones to reach the same effective displacement as 1 larger cone.....imho. [/QUOTE]
