A lot easier and cheaper to get recones for is the aqs. On the getting loud part. It's all about the box. I've seen pair of hdcs put out insane numbers on twice rated power. Orion on the other hand will give you more of advantage if you are limited on space. Them hdcs shine in huge boxes and will play lows. Whoever says they can't are full of shit and prolly clipped one to death before.
