The prompt
Here is the Text-to-CAD prompt for the passive companion monitor. Since this is the passive unit, this prompt removes the side control knob and swaps out the massive rear amplifier cavity for a smaller, standard terminal cup cutout to wire it to the active unit. **Text-to-CAD Prompt:** > A rectangular passive studio monitor enclosure with exact outer dimensions of 285mm height, 175mm width, and 225mm depth, featuring a material shell thickness of 15mm. The front baffle features a 10mm radius fillet on all outer edges. The front face includes four specific cutouts: a 45mm diameter circular cutout centered horizontally at 220mm from the bottom edge for a tweeter; a 120mm diameter circular cutout centered horizontally at 110mm from the bottom edge for a 5-inch woofer; and two 25mm diameter circular cutouts positioned 35mm from the bottom edge and spaced exactly 90mm apart for front-firing bass reflex ports. Both the left and right side panels are entirely solid with no cutouts. The rear face features a smaller 75mm width by 50mm height rectangular cutout, recessed by 3mm and centered horizontally at 60mm from the bottom edge, designed to house a standard speaker wire terminal cup. The bottom face includes four 15mm diameter, 5mm tall cylindrical extrusions positioned exactly 20mm inward from each corner to serve as mounting points for rubber feet. > **Measurement Changes from the Active Unit:** * **Side Knob:** Completely removed (solid left and right side panels). * **Rear Cutout:** Reduced from the large 250mm x 145mm amp cavity to a compact 75mm x 50mm terminal cup cutout for speaker wire binding posts. * **Front Baffle & Dimensions:** Identical to ensure the pair perfectly matches.
