How about this for those who build their own 5F1 Champ, etc.? We are in the furniture making business. In our spare time, we build amplifier cabinets and speaker cabinets. This is a cabinet previously made for a 5F1 Champ. We selected commercially available SPF lumber with few knots. Speaker: 8-inch specification Body: SPF lumber (18mm thick) Front panel: Oak (10mm thick) Back panel: Lauan plywood (9mm thick) Grille cloth: Guitar Amp Baffle board: MDF (12mm thick) Speaker mounting screws (4-point mounting, 5 x 20 truss head small screws included) Speaker mounting screw position (197mm) Rubber feet: Commercial product Paint: Oil stain (mahogany color), urethane sanding sealer base coat, urethane half-flat finish coat Dimensions: W330 x D200 x H340 (including 10mm rubber feet) Weight: 3kg We put in the effort to build it carefully, so it has a solid construction, which also affects the sound. It also has some weight, so it doesn't feel flimsy. Since the boards are assembled in sequence, the wood grain is continuous. The older growth rings (the outer side of the tree) are on the outside of the cabinet, just as they were when the tree was alive. The body is joined with half-blind dovetail joints. We try to be as careful as possible in the manufacturing process, but there may be scratches, dents, warping, chips, cracks, color unevenness, paint unevenness, and speaker mounting marks that occurred during the manufacturing process, so please judge from the photos. This cabinet does not include a speaker. Please note that this is a listing for the cabinet only. How to install the speaker: Remove the back panel and attach it from the back with the included screws. Be careful not to overtighten the screws. The speaker mounting screw position is (197mm), so please check if it can be installed before bidding. If the screws don't fit due to a slight difference, enlarge the screw holes of the speaker. How to install the chassis: By looking at the drawings, you should be able to determine whether the dimensions of the chassis can be installed. The chassis mounting screw holes are not drilled, so please process and install them yourself. There may be some dimensional errors compared to the actual product.
