It's just a dual basreflex cabinet with one of the drivers inverted. The inverted driver has a small cavity surrounding it, which only purpose is to protect the driver sticking out, simulation-wise it can be ignored. 

Learn WinISD (online or download), simulate the drivers in a reflex cabinet, then build that cabinet. AI can help a great deal in this proces but check back with a human before you start building
