Interesting...what kind of power were they getting? And do you have any idea the tuning? Cause from what I hear the type r's are def. loud if you tune like mid to high 30's but the AP are designed to play lows very wellI dont remember the exact specs but its a pretty big ported box. I dont have this system anymore but i personally rather the type r's. Not trying to knock down your opinion or anything like that just my personal experience with them
