[QUOTE="DNick454, post: 5923576, member: 600755"] Did he recommend 40 sq inches of aero port or slot port? Because 40 sq in of slot port seems way too small for an 18". Even if he is the owner of the company, that just doesn't seem logical to me to be honest. Also, I don't see why you'd lose musical ability by making the port larger in area because you also make it longer to keep the same tuning so the resonant properties of the port are still the same. I've never used RD products so I'll just stay out of this for now I guess, but unless RD subs are some crazy never before used concept in woofer design, I would say the port would be a tad small.
