Fi Car Audio Subwoofers
Fi Car Audio is an American manufacturer based in Las Vegas, Nevada, founded by Scott Atwell (also the creator of RE Audio). Each subwoofer is custom-built in-house using CNC-machined US steel components with 10-14 day build times—no mass production. Their BTL (Blow Through Loud) series dominates daily driver and SPL competition alike, while the Neo series offers refined sound quality with extreme power handling. In August 2024, Fi transitioned to new ownership including leaders from Sky High Car Audio, Limitless Lithium, and SoundQubed, with Scott Atwell remaining as lead designer. Fi subwoofers are built by competitors, for competitors.
