Box was used for 2 Dayton Reference HO 10s and is tuned to about 30hz with one side-firing 4" aero port. Very well built, IMO. Carpeted and all as u can see from the pics.
^that pic just shows where the amp was mounted on top of the box
EDIT: I found my tape measure, then broke it...and attempted to fix and got these outer dims of about 30.5 wide x 12 tall x 13.5 deep Box is fairly compact.
asking..... $115 shipped
