An acoustic shell system includes a frame comprising a first column, a second column, and a base. The first and second columns each comprise a circular portion with a channel along the length of the column where the circular portion is configured to attach to one or more panels. The circular portion is coupled to a noncircular portion opposite the channel having at least one channel along the length of the column and configured to attach to one or more components. The base comprises first and second arms coupled to opposing ends of a cross-support. Each of the arms is also coupled to one of the columns at about a ninety degree angle. The length of the cross-support is less than the distance between the first and second columns.
