The prompt
Create a parametric dual-12" 6th-order bandpass subwoofer. External size: 615W × 435H × 615D mm. All panels: 15 mm plywood. Drivers: 2 × BMS 12N630. Cutout Ø284 mm, frame Ø318 mm, depth 159 mm. Use diagonal internal driver baffles in the 615D × 435H side plane. The two drivers face opposite diagonal corners. Both driver rear sides share one central rear chamber. Each driver front side has a separate isolated front chamber. Each FRONT chamber must be 12.0 L NET air volume after subtracting driver, port and panel displacement. 4 triangular corner ports. Each port has a right-isosceles clear air cross-section: 245 × 245 mm legs = 300 cm². The enclosure corner forms two sides; a 15 mm 45-degree panel forms the hypotenuse. Side-view port positions: upper-left = FRONT upper-right = REAR lower-left = REAR lower-right = FRONT Front ports: 230 mm long. Rear ports: 560 mm long. Front port volume is displacement: do NOT include its 6.9 L inside the required 12 L NET chamber volume. Increase gross front chamber size so 12 L net air volume remains. Keep all 3 chambers acoustically isolated and make the geometry symmetrical and manufacturable from flat plywood panels.
