Powered Subwoofer & Box Build
Kicker’s Free Airs left a legacy in the market. They have almost no enclosure requirements and are often drop-in upgrades. I picked up two used 6.5″ Kicker Free Air subwoofers. “Free Air” is a misnomer, they still need an enclosure. However the enclosure space can be relatively large. The trunk of your car could be considered an enclosure, as long as the space in front of these speaker is sealed off from the space behind these speakers. I don’t plan to put these in a car, they are going to be for a home sound system. I like the early 2000’s sub look that these Kickers have: thickly stitched cones, paint chipped rusting frame, rotting seal, and corroded leads. At one point they were very nice, now they are fair. I can deal with fair speakers if they are free. ...
