I've been recently turned on to Fi by how well people talk of them. From the spec side they look awesome, and from the design efficiency side it seems to be awesome as well. Im setting up a new sq system in a 1991 lexus ls400 and im either going to go 1 15-or 18 or 2 12's mostly because of limited trunk space. Im looking at the q's mainly because their supposed sq prowess. My first question is Can the Q's be mounted free air. And even though the q's are more of a linear bass response sub, do they deliver enough punch to respond well to the lows of a rap/electronic beat. Any comments or input would be greatly appreciated.
