Abstract
An acoustic device includes a resilient surround having a proportionately unequal distribution of half roll and inverted half roll segments. Half roll segments may be sized and located to provide additional clearance for internal components. Regions of transitional concavity may be sized and located to provide increased stiffness in one or more dimensions. Transitions between inversions of concavity may be smooth and free of localized inflexions.
