Heavy duty cover that fits the Zx4 and Zx5 loudspeakers is designed to protect the enclosure during storage and has heavy duty padding on all sides. It utilizes durable 1000D black cordura laminated to foam. It has built-in hard top so that one enclosure can be safely stacked on top of another. This is accomplished with two-ply corrugated top structure with internal rubber protective feet. The rear of the HDC-5 features transparent vinyl pocket that accepts normal cardstock inserts to help identify model and/or serial numbers. This is especially helpful with Zx5 as it is available in different horn patterns. The side of HDC-5 has circular opening that gives access to the handle on the enclosure. This makes it easy to transport the enclosure with HDC-5 maintaining its protective capabilities.
