The prompt

Create a solid box with a width of 180mm, a height of 280mm, and a depth of 220mm. Shell the box inward to create a hollow interior with a uniform wall thickness of 15mm. Select the front face. Draw a circle with a diameter of 125mm, centered horizontally and positioned 180mm from the top edge. Extrude-cut this circle entirely through the front wall to create the woofer hole. Draw a circle with a diameter of 75mm, centered horizontally and positioned 65mm from the top edge. Extrude-cut this circle entirely through the front wall to create the tweeter hole. Select the rear face. Draw a rectangle that is 120mm wide and 160mm high, centered horizontally and positioned 30mm from the bottom edge. Extrude-cut this rectangle entirely through the rear wall for the amplifier plate. Draw a circle with a diameter of 45mm, centered horizontally and positioned 50mm from the top edge. Extrude-cut this circle entirely through the rear wall for the bass reflex port.
