This is a custom-made collapsible speaker cabinet for a 15" speaker. 

• It collapses to nearly half its depth for carrying.  This gives you more internal volume, needed for many bass speakers.

• The front panel can be changed if you want to set it up for tuned operation (a port) or a different size speaker. 

• Finished in black vinyl with aluminum trim.

• Panel in back with one 1/4" jack.

Dimensions:

H: 24"

W: 24"

Depth collapsed: 12.75"

Depth expanded: 22.5"

Internal volume (expanded): 5.4 cu ft.

There is no hardware to hold it in its expanded state -- we never got that far.
